Food grade diatomacious earth


Diatomaceous Earth – Food Grade Benefits & Uses incl. Pest Control

Diatomaceous Earth is a name you probably heard of, but did you know there are several different uses for this product? This particular product is available for public use in several different forms from food-grade to pool-grade. Food-grade Diatomaceous Earth has a lot of uses and benefits that we wanted to tell you about.

What is Diatomaceous Earth?

Diatomaceous Earth is so popular and beneficial because it’s a naturally-occurring element found in nature. Specifically, Diatomaceous Earth is a sedimentary rock that is very soft and can be ground up into a fine white powder.

There are organisms in the water that are known as diatoms and Diatomaceous Earth is produced by the fossilized remains of these diatoms. Silica is the natural substance that the skeletons of these diatoms are made of, and silica itself is now mined in several locations.

You can mine the silica in oceans, streams, lakes, and rivers, and it accounts for 26 percent of the Earth’s crust if you are going by weight. Silicon is a byproduct of silica and when mixed with water and oxygen it will produce silicon dioxide. There are two different forms of silicon dioxide that naturally occur, with one being amorphous and the other being crystalline.

When we talk about Diatomaceous Earth, we are talking about amorphous silicon dioxide. Even though it’s mostly made from the amorphous version, some small amounts of crystalline silicon dioxide can also be present. Back in 1960, production of insecticides with silicon dioxide began and the industry has been growing ever since.

Food-Grade vs. Pool-Grade Diatomaceous Earth

You might have heard about Diatomaceous Earth before because it exists in two different versions. There is a pool-grade version and a food-grade version, but most people aren’t sure what the differences are between the two. In order to become food-grade Diatomaceous Earth, the product has to meet certain standards to be considered safe. Food-grade cannot contain over 10mg/kg of arsenic or lead.

Pool-grade Diatomaceous Earth is treated using incredibly high heat. The high heat actually will turn the silicon dioxide into crystalline silica. Pool-grade Diatomaceous. There is no set standard when it comes to how much crystalline silica is found in the pool-grade version, but some products can be as high as 70 percent.

This is really where the main difference is because crystalline silica is toxic to both animals and humans. It’s dangerous due to these high levels of crystalline silica and can cause severe health problems. Pool-grade Diatomaceous Earth should only be used for filtration purposes.

The food-grade version of Diatomaceous Earth does not use high heat, therefore it doesn’t have crystalline silica in massive concentrations. Food-grade does have a little crystalline silica in it naturally, but it’s less than one percent. A large majority of the food-grade version is composed of amorphous silica, which is safe for human and pet consumption. The food-grade version is what’s used in both insecticides and in some animal feed.

Where Does Diatomaceous Earth Come From?

Diatomaceous Earth comes from aquatic life, so anywhere a body of water is that is where you’ll find this product. You will find it in oceans, lakes, streams, rivers, and other bodies of water where aquatic life known as diatoms are present. Throughout the years, layers of diatoms have sat in the water and naturally turned into silica. Diatomaceous Earth is made from that silica and is regularly mined from these bodies of water.

Is Diatomaceous Earth Safe for Humans?

The food-grade version of Diatomaceous Earth is safe for humans in terms of being around it and consumption. When talking about the pool-grade version, it’s not the safest to handle and proper precautions should be taken. The only issue with Diatomaceous Earth is if you inhale it, and that goes for both the food-grade version and the pool-grade version.

Regardless of what you are using this product for, the main precaution to take is to not inhale the product as that could potentially cause you health issues. It’s always best to use a proper face mask when you are working with Diatomaceous Earth. If you are using this product in your house, make sure to have windows open and a fan going for proper ventilation.

Uses for Food-Grade Diatomaceous Earth

Food-grade Diatomaceous has many uses and benefits regardless of where you want to use this product. Diatomaceous Earth is one of those products that has benefits for both people and pets including as a flea prevention medication and a household cleaning product. Here is a list of just some of the most popular uses of food-grade Diatomaceous Earth.

Pest Control Uses

Diatomaceous Earth has been used for over 50-years as an insecticide and works pretty well as a pest control option. It’s important to note that the food-grade option is what you should be using for pest control. Diatomaceous Earth can kill a lot of different bugs and insects including slugs, worms, mites, and beetles. Spiders and many other small insects can also be killed. Diatomaceous Earth is also a great product for killing fleas both in your home and on your pets.

Using this product you can also kill crickets, centipedes, bed bugs, millipedes, and silverfish. Earwigs and grasshoppers also can be eradicated, along with many other small bugs. If you have a cockroach problem, then use Diatomaceous Earth to quickly and easily get rid of them before it turns into a full-blown infestation.

Health Uses

The food-grade version of Diatomaceous Earth has a lot of health uses and has started to become a popular trend as a dietary supplement. Some of the health benefits of food-grade Diatomaceous Earth include promoting healthy skin and nails, encouraging hair growth, and improving overall bone health.

It’s also said to help clear out the digestive tract and also aid in healthier digestion. The body also gets a small amount of trace minerals which is important for your internal organs. This product also helps improve heart health by lowering cholesterol levels.

Household Uses

Diatomaceous Earth has a ton of household uses and it’s really beneficial to use it as an odor neutralizer. You can sprinkle a small amount in the bottom of your garbage cans to help eliminate odors. It helps eliminate foot odors as well that might be hidden in your shoes. Just take an old sock and put some Diatomaceous Earth in the sock and place it inside the stinky shoes. You can leave it there until you want to wear your shoes again.

Leave a small open container of Diatomaceous Earth in your refrigerator to eliminate nasty odors from there just as you would baking soda. You can replace the small batch once a week to maintain the freshness. Diatomaceous Earth also can be used as a household cleaner and can be used on a variety of household items.

You can use this product to get out carpet stains by sprinkling the product over the stain and then letting it sit for at least two hours. After two hours you can vacuum up the powder and the stains will have been removed. Cleaning sinks, faucets, and tubs is also possible with this product.

The same cleaning method works for spills in your garage as well, including oil spills. You will need to let the Diatomaceous Earth sit on the oil spill for 24-hours or so before you scrape up the product from the floor. Diatomaceous Earth also works as a face mask and cleaner and it works as an exfoliate. Just mix some of the powder with water until it forms a paste. Rub the paste on your face using a circular motion and let it soak into your skin for about two minutes. You can then rinse it off with warm water and you will have noticeably smoother and cleaner skin.

FAQ on Diatomaceous Earth

How Long is Diatomaceous Earth Effective For?

Diatomaceous Earth can be effective for quite a long time depending on how you use the product. When talking about storing the product, as long as it’s in a dry and cool place properly sealed, there is no expiration date on Diatomaceous Earth.

As a pest control option, it will work for as long as the area remains dry and isn’t disturbed by being blown away. Once the area gets wet, you will need to reapply Diatomaceous Earth to maintain effectiveness as an insecticide.

Can You Put Diatomaceous Earth on Dogs?

You can put Diatomaceous Earth on dogs as long as you are using the food-grade version of the product. Using Diatomaceous Earth on your dog can help as a deterrent for both fleas and ticks. Since Diatomaceous Earth is a natural bug repellent, it can stop bugs from biting your dog while out and about.

Not only can you put Diatomaceous Earth on dogs, but you can feed it to them as well to help get rid of worms. Hookworms, roundworms, pinworms, and other internal parasites can be killed off by feeding this product to your dog. You will need to feed them a certain amount depending on their size with small dogs only needing ½ teaspoon a day.

1 teaspoon for a dog that is under 50 pounds, 1 tablespoon for a dog over 50 pounds, and 2 tablespoons for dogs that are over 100 pounds. Feed them this mixed in with their food once a day for 30 days to get rid of all of the worms.

You can use this same formulation if you want to feed Diatomaceous Earth to your dog as a dietary supplement. There are many minerals found in Diatomaceous Earth including magnesium, calcium, and iron, which make it a great natural supplement for your pet.

Is Diatomaceous Earth a Carcinogen?

There are a lot of people who think Diatomaceous Earth is completely safe and that it’s not considered a carcinogen due to it being used in pesticide products. In reality, OSHA has labeled Diatomaceous Earth as a carcinogen or possible carcinogen. The IARC labeled it as a Group 3 carcinogen. This carcinogenic label comes from looking at this product as one instead of two separate products.

The food-grade version has not been shown to be a carcinogen in any way due to it having less than one percent crystalline silica. Since the food-grade version is made from amorphous silicon dioxide, it has very little risk associated with it and has never been linked to cancer in any way. So if you are worried about it being a carcinogen for household use, there is no need to be concerned. Most products use the food-grade version so on the average, you don’t need to be concerned with it being carcinogenic.

The carcinogen comes into play with the non-food grade version, which is where the very high concentrations of crystalline silica are found. The pool-grade version is absolutely a health risk to people and animals and studies have shown breathing the pool-grade version in has caused lung cancer in mice. There are still some uncertainties about the real carcinogenic risk of Diatomaceous Earth and studies are ongoing.

I have heard two explanations of how diatomaceous earth works.

One is that on a microscopic level, the diatomaceous earth particles are very sharp looking. These particles stick to an insect and get stuck between its exoskeleton joints. As the insect moves, it gets physically cut up.

The other explanation is that diatomaceous earth sticks to the insect and somehow causes them to dry out. I think this approach involves scratching the insects waxy layer which then allows precious moisture within the insect to get out. So their teeny tiny bug-innards turn into teeny tiny bug-innards-jerky.

A reader, Sue, in Washington state writes:

Both are true and connected. DE is almost pure silica (with some beneficial trace minerals); under a microscope, it looks like shards of glass (glass is made from silica). On any beetle-type insect that has a carapace, like fleas and cockroaches, the DE works under the shell and punctures the body, which then dehydrates and the insect dies. DE is totally nontoxic. There is no buildup of tolerance like there is to poisons because the method of killing is PHYSICAL, not chemical.

The important thing to us is that if an insect with an exoskeleton gets diatomaceous earth on them, they die. At the same time, we can rub it all over our skin, rub it in our hair, eat it …. whatever … and we are unharmed.

Diatomaceous earth kills all bugs. It has been reported to be the most effective solution when fighting pests like fleas, ants and bed bugs.

Farmers dump food grade diatomaceous earth by big scoops in with grains when the grains are stored. It kills the insects that want to feast on the grain. This is a great improvement over the stuff they used to put in with the grain.

Farmers feed gobs of diatomaceous earth (food grade) to animals in the hopes that it will cure whatever ails them. Many farmers swear that the stuff kills all sorts of worms in their critters.

Many people eat a quarter cup of food grade diatomaceous earth every day. They mix it into juice. I have visited with several people that are keen on living past 100 years that believe that eating lots diatomaceous earth every day will help them with that goal. I have found references where it is cited for colon cleansing, parasite control and detox.

One strange thing about diatomaceous earth is that for it to work on killing bugs, you have to keep it dry. Even morning dew can make diatomaceous earth ineffective.

I have encountered over a dozen ignorant boobs that have proclaimed “Diatomaceous Earth does NOT work!” I have read this statement in all caps. In extra big fonts. With italics. And I’ve even had it screamed at me. I’m gonna stick with “ignorant boobs”. On closer inspection of each case there is always a flaw. Usually the problem is that it was not used correctly. Diatomaceous earth is not a bait. If you put a little bit in a pile somewhere, the bugs are not drawn to it and invite all their friends. I kinda wonder if the pesticide companies pay people to go to internet forums and say this sort of thing. Diatomaceous earth is super cheap, non toxic, and generally more effective than anything the pesticide companies have to offer – so it kinda cuts into their profit margins a bit. I’ve been meaning to create an experiment to set the record straight on this topic, but a participant in the diatomaceous earth discussion, Stephanie, beat me to it:

I tried my own experiment with the diatomaceous earth to see how quickly it kills the fleas; I caught a few fleas and put them in a jar with a pinch of diatomaceous earth – all were dead within just a couple of hours.

It just doesn’t get any more clear than that.

Do you eat dirt?

You may find that an odd question, but truthfully, eating dirt has become all the rage these days. Not just any old dirt, but diatomaceous earth. It can be used for any number of things.

Plus, it is really inexpensive.

So if you are puzzled about this dirt craze and how it can be used to treat and help so many different things, then you are in the right place. I’m going to share with you all of the diatomaceous earth uses.

A Variety of Diatomaceous Earth Uses:

1. Body Detox

We are slowly learning as a society that our bodies need to be detoxed because of all the chemicals we ingest on a daily basis that is really bad for our health.

Well, food-grade DE (diatomaceous earth) can help to do that. You can mix it in your smoothie or in a glass of water to help rid your body of toxins.

2. Purifies Water

DE can also be used to purify water. Many water filtration systems include diatomaceous earth in it. So it is an all-natural product that helps keep toxic items out of our filtered water as well.

3. Gives Parasites the Boot

If you take food grade DE, then you need to know that diatomaceous earth is fighting against most parasites you come in contact with.

Also, if you have animals, know that it will do the same for them. That is why it is never a bad idea to sprinkle a little DE in our livestock’s food.

4. Evicts Insects

If you have insects in your home, just sprinkle a little diatomaceous earth where they may be entering your home or on the paths that they travel. It will stop the pests in their tracks.

5. Keeps Your Body Moving

Consuming food grade diatomaceous earth is not just good for detoxing your body. It is also great for your joints, bones, and ligaments as well.

6. Armor for Your Skin, Nails, and Teeth

If you want healthy skin, healthy nails, and healthy teeth, then you need to consider adding diatomaceous earth to your regular diet. But make sure it is food grade and talk to your healthcare professional too.

7. Keeps Your Digestion Going

Do you battle with constipation? Well, then adding a little diatomaceous earth to your diet may also help to improve your digestion as well.

8. Is a Friend to Your Liver and Colon

Detoxing our liver and colon can have a lot of great health benefits. So adding diatomaceous earth to your diet can help to detox to help the liver and colon function better.

9. Gives Your Immune System a Boost

Naturally, if you are ridding your body of toxins, then your immune system is going to be boosted. So adding DE to your diet can also help with strengthening your immune system.

10. Kills Bed Bugs and Viruses

If you have bed bugs or a virus, then don’t panic on either. Instead, sprinkle DE on the affected surfaces and allow it to stop both bed bugs and viruses in their tracks.

11. Boosts Your Energy

If your body isn’t being weighed down with toxins, then everything begins to function inside of you as it should. This in turn creates a lot more energy for you.

12. Protects Rover from Fleas

via The Holidog Times

I use diatomaceous earth as a great flea medicine. I don’t like the price or ingredients of the flea meds at our vet’s office.

So I skip all of the fuss and expense by sprinkling DE on my cats and dogs to rid them of any pesky fleas.

13. Homemade Deodorant Ingredient

A lot of homemade deodorants don’t really work. We don’t want to stop sweat, but we don’t want to smell like a dead animal either.

Well, if you include DE in your deodorant recipe, it is supposed to help absorb some of the odors that our bodies naturally put out. Therefore, helping you to control your body odor.

14. DIY Toothpaste

Diatomaceous earth is also a great ingredient to include in your homemade toothpaste. It can help improve your dental health.

15. Scrubs Your Face

via Bembu

If you would like an organic option to add to a DIY facial scrub, then you might want to consider diatomaceous earth. It has the right amount of abrasion to help clean your skin.

16. Boosts Collagen Productions

Collagen is what so many women try to hang on to so their skin doesn’t get all soft and wrinkly. You can accomplish this by purchasing a lot of fancy moisturizers.

Or you can add diatomaceous earth to your diet. It helps your body to keep producing collagen which is what you are wanting anyway.

17. Helps Your Hair

There are certain items we can add to our hair to help it look healthier. I use apple cider vinegar quite regularly as it helps my hair to stay healthy.

But a new item I’ll be adding to my list is diatomaceous earth. It too is supposed to help your hair stay healthy and shiny.

18. Produces Stronger Nails

Diatomaceous earth has a way of giving our bodies certain minerals and things that it needs. This boost will obviously help you have stronger and healthier nails as well.

19. Helps with Food Storage

If you have large amounts of foods, such as grains, and you are worried about them being destroyed by bugs, then add a little DE to the mix. The same way diatomaceous earth protects your home from bugs, it does the same for your food in long term situations.

You may never have heard of diatomaceous earth (DE) before, but chances are you’ve consumed or used plenty of products that contain it. So what is diatomaceous earth and does it really work?

DE is a powder that comes from the cell walls or shells of diatoms, or aquatic organisms. It’s commonly used by humans to promote detoxification, aid digestion, and improve skin and hair health.

For example, diatomaceous earth for fleas is also extremely effective for your pets. But DE has many uses beyond that, with an astounding ability to kill insects and harmful substances in your home and purify your water.

If you haven’t used this natural substance in your diet, home or garden yet, you’ll want to experience its many benefits.

What Is Diatomaceous Earth?

Diatomaceous earth (DE) is a natural product made up of fossilized remains of tiny, aquatic organisms called diatoms. Composed of the cell walls/shells of single cell diatoms, it easily crumbles to a fine powder.

In fact, the composition of the diatom cell walls are biogenic silica.

The substances used to make diatomaceous earth are safe and taken directly from the sea, since diatom silica deposits accumulate over time in the sediment of rivers, streams, lakes and oceans.

DE goes by many names other than diatomaceous earth, including:

  • dinosaur dust
  • miracle mineral
  • fossil shell
  • ancient treasure

According to the National Pesticide Information Center, diatoms found in DE are actually skeletons that are made up of silica, a very common type of matter found in nature that makes up about 26 percent of the earth’s crust. There are various types of natural silica, many of which you probably recognize, including: sand, emerald, quartz, feldspar, mica, clay, asbestos and glass.

What are some products that contain diatomaceous earth? Diatomaceous earth is available in two different grades:

  • Food Grade — meant to be taken internally by humans
  • Non-Food Grade — used in industrial practices

Some common products that contain diatomaceous earth include dusts, powders (or a “powder duster”) and pressurized liquids that are used on the outside of buildings, on farms, in gardens, and in human and pet foods.

It usually comes in the form of a white powder and is also used in water filtering, food manufacturing, skin products and farming to naturally eliminate free radicals, viruses, insects, parasites and other harmful organisms by binding to them and drying them out. It also has the ability to improve the body’s use of calcium, improve bone mineralization, protect joints and fight effects of aging.

Diatomaceous earth comes in several forms:

  • granulated diatomaceous earth, a raw material made from crushing silica that’s usually available as a powder and safe for human consumption (to be food-grade, it must contain less than 1 percent crystalline silica)
  • milled or micronized diatomaceous earth, a very fine form used in pesticides and insecticides
  • calcined diatomaceous earth, a heat-treated and activated form used in water filtering and explosives

You can purchase food-grade DE in some health food stores or online. DE for your garden or pest control is also available at many home improvement stores.

Silica used to make diatomaceous earth is a key common component of the earth’s natural rock, sands and clays. Silica is an important component of human ligaments, cartilage and musculature and is also abundant in plants since it facilitates their growth and development.

Studies have shown that it’s an essential mineral for the body to build strong bones, hair, nails and teeth, and it’s needed to carry calcium into various parts of the body.

According to research published in the Journal of Nutrition, Health and Aging, many forms of silica exist in nature, and compelling data supports myriad beneficial effects of consuming more silica within water. Orthosilicic acid is the form of silicon predominantly absorbed by humans and found in numerous tissues, including nails, bones, tendons, the aorta, the liver and the kidneys.

Compelling evidence exists that suggests silica is essential for health and has a strong anti-aging effect. Deficiencies in silica can contribute to:

  • abnormal growth
  • deformities in skull and peripheral bones
  • joint pain caused from poorly formed joints and reduced contents of cartilage and collagen
  • disruption of mineral balance
  • damage to the femur and vertebrae

Benefits for the Body

1. Detoxifies the Body

Diatomaceous earth — also known as diatomite — works like a natural detoxifying agent within the body, killing parasites and viruses that can contribute to illnesses while also helping to clean the blood. It’s also inexpensive, simple to use and much safer than many store-bought detox products or plans.

Some of the benefits of using DE internally include reducing odors, helping to curb gas, cleansing the digestive tract, boosting liver function and absorbing harmful toxins within the blood.

How does DE work to help with detoxification?

Silica works similarly to antioxidants found in high-antioxidant foods because it retains its traits as a stable particle even while continuously suspended in a liquid medium, allowing it to fight free radical damage. It’s broken down into a colloidal form, which acts like a detoxifier for the blood since it carries an electrical charge that attaches to free radicals and other harmful toxins.

Silica particles can then neutralize the charge of free radicals and remove them from the body through sweat, urine and feces, which slows oxidative damage and has anti-aging effects.

A study published in the American Journal of Clinical Nutrition found that silica also helps eliminate heavy metals from the body, such as aluminum, making it perfect for a heavy metal detox. In studies, it has been shown to have a high-aluminum-affinity and reduces aluminum availability from the human gastrointestinal tract.

2. Fights Parasites

A 2011 study published in the Oxford Journal of Poultry Science found that DE has the potential to be an effective treatment to help control internal worms (parasites). Interestingly enough, this was observed in hens that produce organically raised, free-range eggs.

Giving two breeds of commercial egg-laying hens DE improved production of their eggs and egg quality compared to control groups, effectively working as a parasite cleanse in the process.

The two groups of hens used in the study were found to differ in their resistance to internal parasitic infections, which was observed by examining their gastrointestinal tracts. The hens fed DE had significantly lower incidences of infections, including fewer Capillaria FEC, slightly lower Eimeria FEC, fewer birds infected with Heterakis and significantly lower Heterakis worm infections.

Those fed DE were also significantly heavier in weight, laid more eggs and consumed more feed than hens fed the control diet, plus their eggs had larger yolks and therefore were more concentrated with nutrients.

3. Improves Joint, Bones and Ligaments Health

A 2007 study published in the Journal of Nutrition Health and Aging stated that dietary silicon is beneficial to bone and connective tissue and helps prevent low bone mass (osteoporosis), which is considered “a silent epidemic of the 21st century.”

Silica within DE helps with normal bone metabolism and joint formation, with evidence over the past 30 years suggesting there’s a positive association between dietary silicon intake and better bone mineral density. Thus, DE makes a great addition to any osteoporosis diet and treatment plan.

A number of possible mechanisms for how this works have been suggested, including the possibility that silicon helps with synthesis of collagen (used to form joints, the lining of the digestive tract and connective tissue) and within the mineralization of bones. While more research is still needed, it appears that silica supplementation can be used to help support normal metabolic processes, preserve joint health and prevent bone disorders.

4. Helps Clean and Protect Skin, Nails and Teeth

Since it has natural abrasive qualities and kills parasites, DE is used in many toothpastes, skin exfoliators, polishes and skin scrubs. Research suggests that just like other beneficial clays — like bentonite clay benefits and uses — DE dries out harmful toxins and leaves behind clean, smoothed skin with little to side effects.

It also seems to have anti-aging effects by helping with the use of calcium in forming strong bones, nails and teeth.

Benefits for the Home

1. Helps Purify Water

Diatomaceous earth is used in many filtration products, including the trademarked brand name Celite, because its chemical composition makes it a great filtration aid. It’s able to filter very fine particles that otherwise pass through or clog filter papers.

This makes it a common product used in water filters to help prevent tap water toxicity and also purification practices for fish tanks. Additionally, it’s also important for manufacturing beer and wine, syrups, sugar, and honey without removing or altering their color, taste or nutritional properties.

A study published in the Journal of Applied and Environmental Microbiology found that diatomaceous earth helps kill viruses and purify drinking water. Viruses have been found to be dangerous and abundant in certain sources of drinking water, raising the risk for viral infections and having a significant impact on bacteria and algae populations in the ecosystem.

Researchers tested the effects of a filter containing DE on tap water that was contaminated with heavy metals and various viral strains. The results of the study showed that DE helped absorb up to 80 percent of the viruses present, including poliovirus 1, echovirus 5 and coxsackievirus B5, which were all present in tap water even after filtration.

2. Kills Insects and Other Harmful Substances in Your Home

In the U.S., DE is classified under the Federal Insecticide, Fungicide, and Rodenticide Act as a safe substance for household use. How does diatomaceous earth work to get rid of insects?

It’s a natural insecticide, since it absorbs lipids from the waxy outer layer of insects’ exoskeletons, which causes them to dehydrate and die of water deficiency. This is why it’s also useful in food preservation, as a natural home deodorizer and cleanser, and for helping to treat livestock suffering from parasites.

Does diatomaceous earth kill fleas and ants? Research suggests that using DE can help eliminate bed bugs, house dust mites, cockroaches, ants (such as ant hills) and fleas within your home without the use for harsh chemicals.

According to the website for Pest Control Technologies, silica gels have been used by the pest control industry for more than a half century since they safely produce an electrostatic charge that helps them adhere to insects crawling over treated surfaces.

Silica gel and diatomaceous earth have been found in studies to kill insects by removing a portion of the razor-thin, waxy outer coating that helps an insect conserve moisture, which allows them to work better than other products that relay on abrasion or poisoning.

How to Use It

You may have wondered, “Is diatomaceous earth toxic to humans?”

Diatomaceous earth is safe for humans and animals to consume and it’s also beneficial for skin, so it’s used both inside and outside the body. Just be sure to check the source and make sure your product is food-grade. Skip using internally if it is not.

The Food and Drug Administration lists food-grade diatomaceous earth as “Generally Recognized as Safe,” which means that it’s legally allowed to be added to many different types of foods, beverages and supplements. Small amounts of silica are normally present in all body tissues and usually found in urine, too, so it’s well-tolerated and not known to cause many side effects.

What is diatomaceous earth used for? As mentioned previously, common products that contain diatomaceous earth include dusts, powders, “powder dusters” and pressurized liquids that are used on the outside of buildings, on farms, in gardens, and in human and pet foods.

In addition, today, there are over 150 pesticide-related products registered for use both indoors and outdoors that contain DE. There are also thousands of non-pesticide, food grade diatomaceous earth products that are used on the skin, in food, and in supplements or medications.

There are a number of ways to use DE. Some of the most popular diatomaceous earth uses include:

  • pet nutrition products
  • products used on dogs and cats to kill fleas
  • bed bug-killing treatments
  • sprays and products used for insect control, including cockroaches, crickets, fleas, ticks, spiders
  • rodent sprays
  • water filters
  • skin care products
  • toothpastes
  • foods and beverages, such as in beer and wine
  • anti-caking and clarifying ingredients used in food manufacturing
  • supplements and medicines
  • rubbers and paints used in construction
  • abrasive products used as defoliators and for cleaning

Here are the recommended steps to subscribe to for safe use of DE as a detoxification agent and to protect bones and joints (but always consult with your healthcare provider before starting a new supplement routine):

  • Take about one teaspoon of food-grade diatomaceous earth powder with water once a day. It’s best used on an empty stomach at least one hour before or two hours after eating.
  • Drink an additional cup of water after each dose of DE to improve its effects. In general, make sure to consume plenty of water with DE and stay hydrated.
  • Increase your dosage slowly over several weeks, working your way up from one teaspoon to two teaspoons daily, or one tablespoon max. Split the dosage into two parts taken in the morning and one at night.
  • Take DE 10 days on and 10 days off for 90 days to effectively and safely detox. Another strategy is to take it daily for a few weeks at a time as you track symptoms, stopping and starting again throughout the year. It’s safest when you give your body breaks and don’t use it continuously for very long periods of time.
  • As a note of caution, initially you might notice some mild side effects that can develop as your gut environment changes, yeast dies off and your body releases stored toxins. This can include mild headaches, fatigue and flu-like symptoms, which should diminish within a couple weeks.

Wondering what DE tastes like? If you’re eating diatomaceous earth, you’ll see that it’s basically tasteless and has a rough, gritty texture.

You can take it with water or mix it into another liquid if you prefer, such as juice, yogurt or a smoothie. It won’t dissolve when mixed into water, so it’s normal to see some residue.

You can stir vigorously before consumption to break it up, but it’s still going to leave behind some chalkiness and a gritty texture, which is why disguising it is a good idea.

Here’s how to use diatomaceous earth in your home:

  • Step 1: Brush and vacuum carpets or any area where you think bugs, insects or fleas could be lurking. This will improve the efficacy of diatomaceous earth for flea and other pest problems, because it aggravates them and gets them to move, which allows DE to work better.
  • Step 2: Apply diatomaceous earth powder where needed in your home, yard, carpets, car, etc. Rub the powder into the carpets with a broom. Use enough to finely cover the surface but not too much that it’s easy to breathe in a lot.
  • Step 3: Let the powder sit for about four to 12 hours before vacuuming. It’s recommended that you repeat this process once a week for a total of three to four weeks.

Risks and Side Effects

Is diatomaceous earth safe? Although it’s generally recognized as safe to use on the body or to consume, some people react to DE by experiencing irritation and other side effects.

It’s possible for diatomaceous earth to irritate the nose and nasal passages when you breathe it in, or if consumed in large amounts, it can contribute to coughs and shortness of breath.

It also has the potential to irritate the skin and cause some mild irritation and dryness. If you have sensitive skin, eyes or nasal passages, it’s a good idea to monitor your symptoms and watch out for any strong reactions.

It’s also recommended that you keep DE away from babies and small children who might be more sensitive to DE’s effects and can react to it by experiencing irritations.

As far as long-term exposure goes, in animal studies generally no health effects have been observed even after applying diatomaceous earth to animals’ skin five times per week for several weeks. In a rat study, researchers fed rats high doses of diatomaceous earth for six months and found no evidence of reproductive or developmental effects.

That being said, the National Pesticide Information Center states that there’s some evidence that inhaling a very small amount of crystalline silicon over time (the kind used in small quantities in some types of diatomaceous earth, especially pesticides) might contribute to silicosis, chronic bronchitis and other respiratory problems in a small percentage of cases. However, the risk seems low considering the vast majority of diatomaceous earth used in products for human consumption is amorphous, not crystalline.

Impact on the Environment

Wondering if garden safe diatomaceous earth can harm animals or contribute to environmental pollution? Evidence shows this is very unlikely and that diatomaceous earth is actually nontoxic to mammals, fish and aquatic invertebrates.

It’s commonly encountered by birds and other wildlife in nature, but has been found to be harmless to birds, fish or other wildlife in numerous studies.

In fact, silica is naturally plentiful in the ocean, and seawater contains vast amounts of diatomaceous earth. The skeletons of many types of sea life and marine organisms are actually made using silica, and therefore it seems to pose no major risks to most species.

As far as plants go, DE can actually be beneficial since it’s used as a growing medium in potted plants. It’s sold as natural soil additive and helps soil retain water and nutrients, while allowing for more oxygen circulation and killing off parasites.

It also helps preserve foods naturally (such as grains or legumes, which can grow mold) and helps replenish soil so more plants and food can be grown for livestock and human consumption.

Final Thoughts

  • Some common products that contain diatomaceous earth include dusts, powders and pressurized liquids that are used on the outside of buildings, on farms, in gardens, and in human and pet foods.
  • Diatomaceous earth benefits include detoxifying the body; purifying water; parasite control; killing insects and other harmful substances in your home; improving joint, bone and ligament health; and cleaning and protecting skin, nails and teeth.
  • Today, there are over 150 pesticide-related products registered for use both indoors and outdoors that contain DE.
  • Diatomaceous earth is available in two different grades: food grade (meant to taken internally by humans) and non-food grade (used in industrial practices).
  • Diatomaceous earth comes in several forms, including granulated diatomaceous earth, milled or micronized diatomaceous earth and calcined diatomaceous earth.

Nobody wants to see this first thing in the morning when they head out to the berry patch.

And if you’re visiting my homestead during the gardening months, you’ll hear us refer to “D.E.” almost daily.

The powdery substance, also known as diatomaceous earth, is one of my favorite weapons against garden pests.

It has saved my family from losing large portions of our garden to beetles, moths, and other crawly things.

What on Earth is DE?

Diatomaceous earth, the official name for DE, is not new.

A popular topic of discussion by many gardeners in recent times, it is an organic gardening pesticide that has been used by some farmers and pest control professionals for decades.

In fact, the powder is often a go-to remedy for household flea infestations as well.

The compound is made from the ground-up bodies of prehistoric diatomic fossils.

When ground, these tiny oceanic skeletal pieces are very sharp, and produce the effect of many miniature razor blades on the respiratory systems of any smaller insect or bug that inhales it. It also causes drying of the mucous membranes of breathing holes and lungs in bugs.

Effective against slugs, beetles, worms, fleas, mites, and most any spider or insect, it is not much of a concern for larger creatures. Because the particles are so small, DE is safe to use around other wildlife, children, and pets.

Anyone who is particularly sensitive to particulates (such as those with asthma or any other type of breathing condition) will want to avoid directly breathing in the dust.

My husband is one such person, and he wears a dust mask to avoid coughing fits and temporary irritation.

What’s the Best Way to Apply It?

My husband carries around a recycled carpet cleaning powder container that he uses to sprinkle liberal amounts of diatomaceous earth on plants in our garden that are the most susceptible to insect damage.

While we may have used Sevin or another toxic product in the past, DE works just as well for us – without the worry of our children ingesting trace amounts of toxic chemicals with each garden snack.

You can sprinkle it directly on the ground where slugs are most likely to reproduce. Or, you can apply a light dusting to the plants themselves.

Diatomaceous earth must be reapplied after every rain or heavy dew to be effective. It’s important to remember that wet DE does not have the drying, cutting effect that’s needed to be work against pests.

All DE is Not the Same

It is important to note that “food grade” diatomaceous earth is the only kind appropriate for use in gardens, and around pets and kids. There are other types that may contain contaminates that are harmful if inhaled or ingested.

Studies on food grade DE, however, have shown it to be relatively harmless to people, even if inhaled in rather large amounts.

As harmless as the food grade version can be for your household, the regular stuff may cause major problems.

The type that is often used in pool filtration systems is not safe to use around kids and pets. Be sure to purchase food grade only and check the packaging for this designation.

As helpful as many garden store employees can be, many are not aware of the differences. It is up to you to protect your family and flock by reading labels, and ensuring that you are introducing a safe pest treatment to your garden.

For more information on the safe use of diatomaceous earth, we like this helpful resource from our friends at Pest Strategies.

DE in the Environment

I want to keep our acreage, and the neighboring land around it, free from harmful chemicals. It’s important that it continues to be a source of food and shelter for my kids, grandkids, and their families.

Diatomaceous earth gives me some piece of mind in that area, as it doesn’t negatively affect the soil or surrounding waterways when used over time. In fact, DE is a sustainable source of silicon dioxide, an essential ingredient needed for poultry development.

Chickens that eat vegetation treated by diatomaceous earth may potentially experience significant health benefits.

Note: While I do not live near the oceans or any major waterways, runoff containing DE simply redeposits the silicon that originally came from the ocean back into it. The silicon continues, undissolved, until it can be used by certain marine life species in building their exoskeletons!

Squash Bugs: A Case Study

If there is one foe of our garden that I have despised more than any, it is the squash beetle. Our soil is perfect for inviting these destructive creatures in, and they have taken out hundreds of pounds of potential pumpkins, butternuts, and melons over the years.

Before diatomaceous earth, we would wait anxiously for them to hatch, then move quickly to harvest before they overtook everything. Now, we have a new plan:

  1. Each day in late summer that the squash beetle is likely to lay eggs, check the undersides of the squash plants. If we see eggs, we act!
  2. Using gloved hands, carefully remove the eggs, being careful not to tear the leaves.
  3. Immediately sprinkle DE on the tops of all of the plants.
  4. Reapply after each rain.
  5. Continue checking for eggs and apply DE throughout the life of the squash plant.
  6. Discontinue application when the harvest is done.

It seems like work, but the reward is sweet! We experience an abundant squash harvest, with no rotting or dead vines, and organic food for my family.

I can’t tell you how good it feels not to worry about chemical residue getting into my family’s meals.

Other Uses for DE

Food grade diatomaceous earth can be a powerful tool for many home and garden ailments.

Added to a sandbox filled with dirt, it makes a good dust bath for chickens, and can keep bird lice and fleas away.

For this use, look for concentrations of the product that contain less than 1% of other ingredients to make sure you are using the purest form for animals.

It is also a potent remedy for fleas in the house. After you find your first flea, liberally sprinkle DE on your carpet and other cloth surfaces, and allow to sit for a minimum of 12 hours before vacuuming.

You may need to repeat this after a week, or when flea eggs are likely to hatch. Repeat 3-4 times to rid your home of stubborn indoor fleas.

A Word on Bee Protection

Bees are our friends. Gardeners should be especially mindful of any products used that may cause issues for our pollinators.

If your garden happens to be attractive to bees, you may consider covering any treated plants with a sheet during the day when bees visit.

Keep an eye on which plants are more likely to bring the bees around, and make note for when the time comes to apply DE.

Most of the plants will be in a flowering stage, which may or may not be during the same time pests are likely to attack.

Getting the Best Price on DE

While you can order it online, be aware that the price per ounce can vary dramatically between suppliers. Your best value will often be found at a local feed store or garden center. Some Amazon sellers have also to earned the repeat business of gardeners who are looking for a more natural option for pest control.

Safer Brand Diatomaceous Earth Insect Killer

Ordering in the off-season and storing what you’ve bought throughout the winter is likely to be the best way to take advantage of low prices.

Why Diatomaceous Earth is For You

While the idea of using ground up sea creatures on your garden may seem strange to you, it’s worth integrating into your pest control routine.

The powder is a very simple product to apply, and it has proven to be just as effective (if not more so) than its toxic counterparts. Keeping a coffee can full of diatomaceous earth in my garden shed leaves me with no excuses – it’s so easy to keep on top of bugs and crawly things.

If you’re trying it for the first time, consider starting with a small project – such as your raised bed of greens. Use it in place of commercial pesticides or other homemade solutions. I think you’ll be amazed at how little you’ll need to use!

Diatomaceous earth, also called diatomite or simply “D.E.”, is a chalk-like substance that’s a naturally occurring substance mined from lake beds. It consists of fossilized diatoms, which are a type of single-celled planktonic algae that lived in oceans and freshwater lakes years ago. There are several benefits for using diatomaceous earth in an organic garden, including eliminating the need for chemical pesticides.

Aphid Control

Aphids are rice-sized green pests that feed on plant juices by piercing young plant parts and sucking the sap. This will stunt plant growth and reduce yield. Dust aphid-infested plants with the diatomaceous powder or mix it with water and spray on plants with a sprayer.

Ant Killer

Ants indirectly destroy garden plants through the use of aphids. Ants “farm” aphids by carrying them to new plants and protecting them from predators. The ants then “milk” the honeydew from aphids in return.

Dust garden plants and ant hills with diatomaceous earth to get rid of them.

Organic Pest Control

Diatomaceous earth is a safe, non-toxic way to control pests in the garden. It’s effective against all insect pests that crawl on plants because contact with the powder is extremely dehydrating.

Water plants, then dust with the powder. The moisture will help the powder stick to plants better.

Slug Away

Slugs are nocturnal pests that like to feed on garden plants under the cloak of darkness.

Protect tender plants by creating acircle of diatomaceous earth around plants. When the soft body of a slug comes in contact with the powder, the sharp particles inflict tiny cuts on the skin and they quickly dehydrate.

Fly Deterrent

Flies are an annoyance to gardeners, but they can easily be kept away with an application of diatomaceous earth.

Sprinkle the powdery organic product liberally on all plants and on the ground. Flies tend to avoid treated areas.

Maggot-Free Compost

Fresh manure and compost piles can house the larvae of many types of flies. While maggots aren’t harmful, the resulting flies are a source of aggravation.

To keep the compost pile maggot-free, just sprinkle diatomaceous earth all over it.

Reduce Rodent Population

Rats, moles, mice, and rabbits often do great damage to your garden, but can be deterred from visiting the garden with the use of diatomaceous earth.

Add a few drops of the essential oil of lemon or peppermint (rodents hate both scents) to the powder, then sprinkle it around the garden perimeter. This highly porous substance absorbs the oil and retains the scent for several weeks.

P.S. It’s edible!

You can add it into yogurt, oatmeal, applesauce, smoothies, coctails and more. It is known to be beneficial to one’s hair, skin and nails. You can learn more about the beneficial effects of food grade diatomaceous earth here:

Food Grade DE Supplier Australia

Diatomaceous Earth Online™ is a leading diatomaceous earth supplier offering superior grade products. We supply premium-grade Australian diatomite (also known as natural amorphous silica).

Our food grade diatomaceous earth has many uses and we are one of the few suppliers with a high-quality product producing diatomaceous earth in Australia.

Sourced from natural freshwater upland extinct volcanic lakes in Northern Queensland, our range of food grade diatomaceous earth is enriched with minerals and naturally occurring silica. With its combination of minerals, diatomaceous earth offers a range of incredible benefits.

What is diatomaceous earth?

Diatomaceous Earth (DE) is an extremely versatile natural product that is derived from pure fresh water sources. It is a sedimentary rock that is made up of underwater single cell animal remains known as diatoms. DE powder is in turn produced by processing these rocks. Enriched with minerals, Diatomaceous Earth offers numerous benefits and has many uses which can be found here .

Our freshwater DE is taken from the ancient freshwater lakes of Mount Garnet, Far North Queensland. We process the Diatomaceous Earth directly from the mine, enabling us to ship diatomaceous earth in Australia and internationally.

Hot Tips:

No 1. Don’t be fooled by other smaller bags of Diatomaceous Earth with fancy packaging. Some of these brands make exaggerated claims that make their product look superior but in reality, their product is just regular food grade Diatomaceous Earth just like this product but sold at a huge markup, up to 7 times the price. This DE is super fine, organic, food-grade, and as good as it gets, so keep this in mind when purchasing.

No 2. Not every brand of Diatomaceous Earth has the same weight! Some brands can be much heavier meaning that you get less dust for every kilo you purchase. Our 4kg bag is about 13.3 Litres in size. Don’t be fooled by heavier and lower grade alternatives.

No 3. This DE is extremely fine in grade with an average particle size of 10 microns. This fine grade makes it far more effective at killing insects than cheaper coarser grades on the market. Coarse DE is a cheaper type of DE and is not too be compared with this super fine product. See below for a coarser and cheaper type of DE, Diatomite Fines.

International Uses: Internationally, Diatomaceous Earth has a wide range of uses in organic agriculture and household pest control and is included in products which are registered, marketed and certified for the control of cockroaches, silverfish, ants, fleas, flies, ticks, lice, earwigs, aphids, whitefly, beetles, loopers, mites, snails, slugs, leaf hoppers. Diatomaceous Earth is also popular as an animal and equine supplement.

Disclaimer & Australian Registered Uses: Please note that Diatomaceous Earth is not registered in Australia for many of the international and other uses listed above. In Australia its range of registered uses is limited to the following: For the control of various stored product insect pests in farm-stored feed grain, farm-stored seed grain, grain for human consumption not handled by or delivered to bulk grain handling authorities, harvesting and other grain-handling machinery, grain bins, silos and other storage facilities, food processing and warehouse facilities as per directs for use.

Current Australian research and product development is focused on:

  • Bed bugs.
  • Poultry pests: Red mite, Darkling beetle and Lice.
  • Internal Parasites of stock: poultry, goats and sheep.

Frequently Asked Questions:

Q. Is this Diatomaceous Earth safe for humans to eat?

A. The product is registered as food grade for specific uses, but we cannot say conclusively if DE is safe to eat because it is not registered for human consumption in Australia. However, we do know staff members and friends of ours who do take this DE regularly by mixing it with juice or water and none have reported serious ill effects and virtually all have been happy with the results.

From the Manufacturer: There is nothing about raw diatomite (diatomaceous earth) that is harmful to human health. In theory, it is perfectly safe for human consumption and many people, all over the world, consume it on a regular basis for various purported health benefits. Even though our diatomite is the purest diatomite mined in Australia (typically 90-95%) and nothing is added to the diatomite during processing, we do not recommend our products for human consumption. This is because we don’t prepare them under the aseptic conditions government regulations require for products designed for human consumption.

Q. What is the Country of origin of this Diatomaceous Earth?

A. Australia.

Q. Is this Diatomaceous Earth from freshwater or saltwater diatoms?

A. Freshwater. Mostly melosiraspecies.

Q. Is Diatomaceous Earth safe to use for flea Control on Kittens that are 3 weeks old?

A. We can’t comment on how safe Diatomaceous Earth is because it’s not registered for this kind of use. However, we have known people who have used it on young kittens without any ill effects.

Q. What is the average particle size of this Diatomaceous Earth?

A. According to the manufacturer, the average particle size is 10 microns, but it can contain particles up to 200 microns.

Q. Why does the packing of this item not mention “Food Grade” or “Diatomaceous Earth” and how can i be sure it really is food grade DE?

A. We have been sourcing this product for many years from Mount Sylvia Diatomite and they have assured us that this product is indeed Food Grade Diatomaceous Earth. We are not sure why the manufacturer decided not to mention food grade or DE on the packing but it likely has more do with marketing and to focus on their brand of DE called “Absorbacide”. The manufacturer of this item refers to this item on their website as Diatomite which is synonymous with DE.

Q. What is the amount of crystalline silica in your food grade diatomaceous earth?

A. Diatomaceous earth, which is a natural product, derived from the remains of freshwater plankton. The product contains no detectable cristoballite. It may contain up to 3% quartz.

Chemical Ingredients Powder Name CAS Proportion

Diatomaceous earth 61790-53-2 96%
Silica as quartz 14808-60-7 <3%

Note From Manufacturer: What this means is that there is no detectable crystalline silica in our diatomite. Technically, quartz (beach sand) is crystalline silica but is usually not included in estimates of crystalline silica. We commonly have around 1-3% of this in our diatomite. This information can be seen on the products MSDS, see download tab

Q. Can the DE be used for a chicken dust bath?

A. I haven’t got a definitive answer but from what I know already and from what I’ve read online it’s probably best not to use Diatomaceous Earth for chook dust baths since it may lead to too much DE dust being breathed in which may be harmful. DE is best applied when the amount that reaches the face of the bird can be minimised but I don’t think dust baths allow for this.

Q. Is this DE white or Grey powder?

A. The colour does vary from batch to batch, but it’s usually a very light grey. Sometimes it can be more white or more grey depending on the batch.

Q. Why does this DE product not include instructions for its many other uses?

A. This product is only registered in Australia for very limited uses like for grain storage pests, therefore the manufacturer is not legally allowed to put application rates for other uses in Australia. However, in the US and most other countries, Diatomaceous Earth is allowed for many more varied uses and application instructions for these uses can be found on Youtube or for more detailed information consider the book “Going Green Using Diatomaceous Earth: How to Tips” (see below)

Q. Do you have an analysis of this DE?

A. Click here is an analysis report for this DE product from the manufacturer.

Q. Is Diatomaceous Earth suitable for controlling ticks in the garden?

A. According to the book “Going Green: Using Diatomaceous Earth” there is anecdotal evidence that DE is effective on Brown Dog Tick.

Q. Is this Diatomaceous Earth suitable for use as a horse wormer?

A. Yes, apparently DE is suitable for this purpose though its not registered in Australia for this kind of use. I’ve read this in multiple places and I also looked it up in the book Going Green: Using Diatomaceous Earth How to Tips. This book states its suitable for internal parasites in animals including horses.
