Food Grade Diatomaceous Earth

Food Grade Diatomaceous Earth (Fossil Shell Flour) has many uses: in the household, with pets, on plants, around livestock, and for stored grain. It is totally organic and listed with OMRI. Read on for the most common uses.

Home: Food Grade Diatomaceous Earth as an Organic Pesticide


Diatomaceous Earth (DE) is used around the house as an organic pesticide for the control of ants, bedbugs, cockroaches, silverfish, box elder bugs, scorpions, crickets, and many other unwelcome pests.

Natural bedbug control is one of the biggest reasons for the usage of DE in and around the home. For complete bedbug control, simply sprinkle the area of concern with fossil shell flour . When the pests come in contact with the powder, it is like stepping on broken glass; they will be killed or abandon the area. It is an organic pesticide for ants, bed bugs, cockroaches, silverfish, box elder bugs, scorpions, crickets, and many other unwelcome pests.

Pets: Diatomaceous Earth Food Grade for Flea, Tick, and Lice Control


Getting rid of fleas, ticks, lice, and other pests that bother our your pets with fossil shell flour can be done several different ways. Take the diatomaceous earth and rub a handful into their coats. For natural tick and flea control, simply sprinkle it on their bedding, in the yard, or add it to the carpets. Use the hand held Pest Pistol Duster for easy pet dusting.

Food Grade Diatomaceous Earth is also used internally to remove parasites and worms from your pets without the use of chemicals. Feed large dogs 1 teaspoon; cats and small dogs 0.5 teaspoon per day. It has been suggested that infected pets should be fed DE for 90 straight days, and then continue feeding every 3rd day.

Plants: Food Grade Diatomaceous Earth as a Natural Insecticide


Use Perma-Guard Food Grade Diatomaceous Earth as a natural insecticide for the non-chemical control of aphids, whiteflies, beetles, loppers, mites, leafhoppers, and other insects. Sprinkle it on fruits, vegetable plants, flowers, grains, and grass—up to and including the day of harvest.

Diatomaceous Earth controls insects by using physical, not chemical, action: It punctures an insect’s exoskeleton and absorbs its body fluids—thus posing no harm to warm-blooded life. Moreover, on any surface, this natural pesticide has a remarkable repellency factor. As long as DE is present, insects tend to stay away, making a serious infestation unlikely. The more it is used, the more an environment is created which makes insects feel unwelcome.

For young plants, as little as 2 lbs. of diatomaceous earth per acre may be adequate. For larger plants, 5 lbs. per acre is probably sufficient. It applies best when there is dew or after a light rain. It is a long-lasting, natural, effective powder, impossible for insects to build up a resistance against.

Livestock: Eliminate Worms and Parasites with Food Grade Diatomaceous Earth


All livestock—horses, cows, pigs, sheep, goats, rabbits, chickens, and others—will benefit from Perma-Guard Food Grade Diatomaceous Earth. Some of its benefits include stimulating basic metabolism; converting feed better; reducing odor and moisture in barns and stalls; improving coat and hoof condition; keeping fly larvae from developing in manure, noticeably reducing the fly population; lowering annual vet bills; killing worms and internal parasites without chemicals; promoting healthier egg production and stronger eggs; and reducing overall animal stress.

We recommend feeding the following amounts of DE for a minimum of 90 days without interruption, and then feed every 3rd day thereafter:

  • Sheep, goats, and hogs ingest 1 oz. per day.
  • Cows and horses ingest 2 oz. per day.
  • For chickens and other livestock that you cannot hand-feed individually, weigh their feed, then add 2% of that weight in DE to their feed.

As an additional benefit, fossil shell flour (DE) contains over 14 trace minerals which improves animal health.

Stored Grain: Pest Protection with Food Grade Diatomaceous Earth


Just add 7–10 lbs. of diatomaceous earth food grade to each ton of grain as it is conveyed into storage. When added to grain, DE kills any bugs that are present. It also protects the grain from further invasion. And bugs cannot become immune!

Note: Though completely harmless when ingested, diatomaceous earth—just like any dust—should not be inhaled in large amounts by pets or people.

Origins of Diatomaceous Earth


With more than 600 deposits of diatomite west of the Mississippi—and only four (to our knowledge) that can be considered food grade—it is very important that people know what they are using. The vast majority of diatomite deposits are impure.

When diatomite is formed, water currents bring in foreign material that mixes with the microscopic diatom shells. This type of diatomite is absolutely without value for practical purposes, but many people tend to think that if it is "Diatomaceous Earth,” then it has the same value as other, purer deposits. There are many places where diatomite deposits can be loaded up "for free,” but generally this substance has no value. If this impure diatomite is sold for practical usage, the customer may end up with an unpleasant surprise.

For dry applications, we recommend using a garden duster.

Our Perma-Guard Food-Grade Diatomaceous Earth is mined from the purest fresh water deposits. It contains less than .05% Crystalline Silica. We are glad to furnish an analysis upon request. We also have smaller 6-oz bottles and larger 50 pound bags of Diatomaceous Earth available.

Comment: This DE I use all the time. I keep a supply on hand. I dust the yard 2 to 3 times a year and we no longer get fleas! Also, I dust the food areas or damp places like the bathroom where Silver fish have appeared and DE clears aways these critters too!

Comment: I have been using Diatomaceous Earth for about 5yrs. I started using it when I found out that it can destroy all parasites in your body. They say that 80% of people who have pets have parasites in their body. So my husband and I have been taking a tablespoon of diatoms in our fruit smoothies twice a day. I also sprinkle the proper amount on my pet's food every day. It's much better than giving them those harsh chemical wormers. I have searched the net, and you have the best price. Thanks for mak... More details

Comment: Well let me start by saying I have more than a few health problems. I have read so many testimonies from all different web sites and compared prices. First let me say the price of this 5lb bag was the cheapest from anyone else. I am only on my third day but one thing I noticed, I have receding gums and have been brushing my teeth and noticed every day they are healing, like the gums are coming together to cover the root, amazing. This alone saves me several hundred dollars because I was suppose ... More details

Comment: Have read great reviews throughout and a few have complained about how dusty their homes get when they use Diatomaceous Earth to control pests, but that won't bother me since I use baking soda to neutralize odors and am used to "dust" besides life is dusty anyway :). I do look forward to great results though I know it will take time to see them. Such is life!
