DE Diatomaceous Earth -50 lb

DE, or Diatomaceous Earth, has many uses. The EPA has approved it as an anti-caking agent in animal feed and as a natural pesticide for indoor and outdoor crawling insects. In addition, DE is approved by the FDA for internal and external use as a Food Grade Chemical.

If you are bothered by any of the following pests, DE is a good way to fight them: ants, bedbugs, box elder bugs, carpet beetles, centipedes, crickets, cockroaches, earwigs, fleas, grasshoppers, millipedes, slugs and silverfish.

Diatomaceous Earth is odorless and nontoxic and looks like white powder. It is composed of finely milled DE of minuscule organisms called diatoms (image at right). The microscopically fine, sharp edges desiccate the insects' exoskeletons upon contact, and the pests dehydrate and die within hours. The insects also die when they eat the dust. Use the Dustin Mizer for easy application.

Indoor and Outdoor Application: Sprinkle a light layer of Diatomaceous Earth in areas where pests frequent, including under stoves, cabinets, sinks, garbage cans, window and door frames and sills, entrance ways, sewer pipes and drains, and in cracks and crevices. Repeat treatment as needed.

DISCLAIMER: Any food grade diatomaceous earth uses other than those approved by the EPA, FDA, or USDA are strictly based on what others reportedly have done. The information that follows is not intended as a substitute for a veterinarian’s advice, nor is it a substitute for your judgment. It is best if you inform yourself and make decisions based on what you learn

Since this is food grade Diatomaceous Earth, it can be taken internally. Internal and external pests and parasites tend to be worse in animals with mineral deficiencies or other health issues. DE may be fed on a continuous basis to larger livestock for both parasite control and mineralization. DE is an excellent source of organic silica and a few trace minerals. The animal’s digestive system is not harmed by its passage; in fact, it converts some of the silica into calcium. The calcium is then used by the body to build bone, teeth, connective tissue, and is also important for the strength of body cells. DE can be part of any balanced mineral program in livestock.

Parasite Control for Livestock: For effective use, the DE must be fed long enough to catch all the newly hatching eggs or cycling of the worms through the lungs and back to the stomach. A minimum of 60 days is suggested at 2% of dry weight of the grain ration. If livestock or horses still test positive, increase the dosage. More will not hurt; too little will not help.


If as much time was spent applying diatomaceous earth (DE) to insect infestations as is spent writing about it, the pesticide companies would go out of business However, if someone doesn't keep writing about DE it seems to fade into the background. This could be explained by the fact that Dow, Monsanto, Union Carbide and other manufacturing companies don't really want their profitable poisons replaced by an inexpensive, non-tonic, naturally occurring, low margin material found in many countries of the world. Diatoms are the grass of the oceans and lakes. Just as green grass is the staple food of earth animals, Diatoms (algae) are the food of the ocean or fresh water grazers. These tiny organisms are protected by a crystal shell which looks like a miniature sand dollar. When DE organisms die, the shells pile up on the bottom to form deposits. These deposits are then mined from underwater beds or from ancient dried lake bottoms. Once DE is mined, it can be milled or processed into a myriad of types for an even greater variety of uses.

DE Flour used in agriculture must be milled until it is almost completely amorphous. This means it has no crystalline form left to cause damage to larger organisms instead it has small sharp edges which can damage tiny parasites, larvae, on stored grain, in animal manure, on infected plants and in the stomachs of livestock and people. The microscopic shells in DE Flour diatomaceous earth are composed of silica and at least 14 trace minerals. Being formed under water, they will not dissolve in water. In fact, even in the stomach of animals or birds, surrounded with powerful digestive juices, they pass all the way through the body almost complete. A very small amount is leached out. As it passes through the stomach and intestinal tract, a number of important things happen. These happenings occur as physical actions, not CHEMICAL, not NUTRITIONAL - JUST PHYSICAL! AND SAFE!

The shape of these shells and the size of the holes in the surface of these shells are very important. In addition, each individual shell has a strong negative charge and it is very fortunate that many harmful things entering the body have a POSITIVE CHARGE. Acting as a magnet, the negatively charged shell attracts and absorbs positive things that are small enough to go through the holes.

Because of the strong charge, each shell can absorb a large number of positively charged substances. Whether they be chemical or in the form of bacteria or viruses. They pass on through the stomach and intestine, taking these harmful substances out of the body. In today's world, most of all food, (animal or human), all water and air contains harmful substances, which taken internally causes stress on the immune system.

Since it also has an attractive mineral composition, food grade DE flour users have reported four distinct uses on the farm: parasite control, mineralization, deodorization/absorption, and grain protection. Each use has its own folklore, facts and fiction associated with it so each will be discussed. Any uses other than those presented her, are strictly reports of what people have done with the food grade DE flour diatomaceous earth.


DE Flour has been used for at least two decades as a natural wormer for animals. It is believed that the DE Flour scratches and dehydrates parasites. Some scientists believe that the DE Flour is a de-ionizer or de-energizer of the worms or parasites. Regardless of the method of operation, farmers report definite control. For effective use, the DE Flour must be fed long enough to catch all the newly hatching eggs or cycling of the worms through the lungs and back to the stomach. A minimum of 60 days is suggested at 2% of dry weight of the grain ration. Caution: do not give to very small pregnant animals such as cats, guinea pigs, etc. and do not feed continually to babies or very small adult animals such as cats, hamsters, etc. The material may be fed on a continuous basis to larger livestock for continuous parasite control and mineralization which is the next major use.


If you began feeding DE Flour to your poultry or livestock and noticed a gain in production, what could the gain be attributed to? The obvious answer would be that the DE Flour reduced the parasite population which resulted in decreased stress on the animal and increased food assimilation. But what about the "mineral" content of the DE Flour? If oyster shell meal provides calcium, then finely ground DE Flour may also provide a broad-spectrum of naturally occurring chelated minerals. These include calcium, magnesium, iron, phosphate, sodium, titanium, potassium and others. Numerous reports of gain have been reported when adding DE: to a ration. With lack of mineralization in modern grains, it isn't hard to conceive of mineral benefits from a finely ground natural mineral product. An Alabama study on hogs showed complete stopping of wood feeder chewing when DE Flour was added to the feed ration. Feeding at 2% of grain ration can take care of both de-worming and mineralization. Most livestock will acquire a "taste" for the mineral if a small amount is mixed in with other feed. After acquiring a "taste" for DE Flour they may take it free-choice. Test results (University of Illinois) in 1966 show that the use of the product does not harm animals or leave residues in milk or meat.


The third major farm use can be an added benefit from the first two uses. Deodorizing and absorption are natural functions of DE Flour. These will continue to happen as undigested DE Flour passes through with manure. Reduced fly hatching is usually observed in manure from livestock fed DE Flour. Some dairy and hog farmers are also spreading it in bedding (for odor and moisture control) in addition to that coming through the manure.


The last use to discuss is grain and flour storage. DE Flour offers the only easy answer to chemical contamination of stored grain. Irradiation could be used, but cost and negative health effects make it very undesirable. This writer has kept wheat, oats, and spelt in open bins for two years or more with no insect damage by applying DE Flour at approximately 7 pounds pet ton of stored grain. The DE Flour was sprinkled into the auger by hand As an examination of its effectiveness, it was compared with malathion and untreated grain on 1,000 bushels of wheat by the Agricultural Research Service of the USDA. After 12 months storage, the DE Flour treated material had 15 insects compared to 4884 for malathion and 16,994 for untreated. Although 7 pounds of DE Flour may lower the commercial grade of wheat immediately after treatment, the wheat maintained its grade longer than other treated or untreated grain. Flour yielding and bread baking qualities are not affected. The new patents allowing DE Flour to be used effectively at 1 to 2 pounds per ton instead of 7 pounds should eliminate any grade deterioration problems. Recent grain board tests in Canada have proven in the field what the patents claimed on paper, i.e. DE Flour protects stored grain without contaminating it. We prefer fresh water diatoms to sea types for several reasons. The bio-activity seems to be better and the health ramifications of breathing the fine white dust seems to be almost negligible because of its 99% plus amorphous structure compared with a higher percentage crystalline structure.


A cookie –cutter conventional approach involves using chemical wormers at set time intervals. This approach has numerous pitfalls and can actually add to the problem. Many horses that are frequently chemically de-wormed often have the highest parasite loads when tested. That is not to say there is never a time to use chemical products, but they should be considered as a last resort and only when other environmental and diet changes have been made. Used indiscriminately, chemical wormers have a number of detrimental effects.

· They over-tax the liver and can kill off beneficial gut bacteria.

· Give you a false sense of security.

· Contribute to “super parasites” that are becoming resistant to common equine wormers.

· May inhibit the horse’s ability to develop natural immunity through exposure.

· Can use a quick kill-off, resulting in impaction colics and high toxin levels from the dead worms.

· Can negatively affect the earthworms and beetles important to a healthy natural environment.

With so many people adopting a natural approach to horse care, more and more questions are being raised about parasite control. Do horses need to be routinely wormed with chemical wormers? If so, what are their drawbacks? Why do some horses carry a heavy parasite load while others don’t? Are there natural ways to deal with parasites?

The conventional approach is to “attack the worms” directly with frequent toxic chemicals, often on a daily basis, without knowing if there is even a problem. The holistic approach recognizes that worm problems are a sign of imbalance and weakness in the body, and that this must be addressed before healing can occur.

Determining if Your Horse Has A Parasite Problem

Periodic fecal exams tell you if there is a high or low egg count. They are a great tool for developing a parasite control program. They help you decide whether any worming is necessary (don’t worm unless there is a problem), and what they type and frequency of treatment (whether natural of chemical) should be. They can also help gauge the efficiency of your worming program or product by testing before and after using a wormer, and looking for a significant drops in eggs. An absence of ova. Especially after only one test, does not mean your horse is parasite free; nor does a single high egg count mean your horse is infested.

“Many of my clients now do a fecal count before administering wormer,” says Catherine Bird, author of A Healthy Horse, The Natural Way (www.happyhorses.com.au). “This way they can do a screening and know which worms they are targeting, and choose the most appropriate product. This has reduced their need to introduce chemicals to once or twice a year, if needed.”
