Diatomaceaous Earth is a naturally-occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off-white powder used as an insecticide.

Also known as fossil shell flour, DE is an excellent antifungal, insecticide, filtration aid, and safe absorbent for spills, odors, and more. DE can be used in your gardening to reduce insects and add minerals to the soil, and in your home and animal care to help kill and reduce: fleas, ticks, mites, fly eggs and larvae, spiders, roaches and bedbugs.

CAUTION: Do Not Breathe The Powder In While Using.

100% pure Diatomaceous Earth from a fresh water source.

Food Grade Diatomaceaous Earth
Also called Fossil Shell Flour, has many health benefits. Diatomaceous earth consists of diatoms, a type hard-shelled algae which is a fossilized deposit of microscopic shells created by one celled plants called Diatoms. These plants inhabit all the waters of the earth, and serve as the basic food for aquatic life, just as grass is the basic food for land animals. Some of these deposits, shifted to dry land, are extremely important to humans.

Diatomaceaous Earth is a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off-white powder. It has a particle size ranging from less than 1 micrometre to more than 1 millimetre, but typically 10 to 200 micrometres. This powder has an abrasive feel, similar to pumice powder, and is very light as a result of its high porosity. It is used as a filtration aid, mild abrasive, and mechanical insecticide.

Diatomaceaous Earth is used as an insecticide, due to its physico-sorptive properties. The fine powder absorbs lipids from the waxy outer layer of insects' exoskeletons, causing them to dehydrate. Arthropods die as a result of the water pressure deficiency, based on Fick's law of diffusion. It can also be used to help control and eventually eliminate cockroach and flea infestations and has wide application for insect control in grain storage. It has also been used to control bedbug infestations, but this method may take weeks to work. DE can be used on bedding and rubbed into animals' fur to kill fleas and mites.

Uses in Gardening

  • Beneficial as a soil additive-safe for earthworms
  • Diatomaceous Earth will not harm earthworms. Earthworm farmers use it to treat their worm beds for parasites, fungus gnat larva etc. Earth worms are structurally different from insects in that they can actually digest particles of DE. The particles are then eliminated in their castings.
  • Works against gastropods and is commonly employed in gardening to defeat slugs and snails.
  • Will help reduce garden pests when used in the soil and sprinkled on plants.
  • Mix into soil for a soil conditioner. Will retain over 6 times its weight in moisture and will release it as the plants need it. It may also help with nematodes.
  • Antifungal properties – good for garden fungal growth

What veterinarians, researchers, integrated pest management, and users of quality Diatomaceaous Earth report:

  • Absorbent -useful for spill clean-up. The U.S. Center for Disease Control recommends it to clean up toxic liquid spills.
  • Reduce fly hatch. Keeps fly larvae from developing in manure, noticeably reducing the fly population
  • To remove odors – shake on manure, urine, vomit, or spills to absorb odors and moisture
  • Reduces moisture and odors in barns, stalls, coops, kennel, litter boxes, compost piles, and other moist areas.
  • Use in facial masks to absorb excess oils
  • Kills many bugs by dehydration-environmentally safe
  • Use to dust animals and animal bedding
  • Use in cat litter to absorb moisture and odors
  • Lightly rub diatomaceous earth into pets coat and bedding
  • On lawns, will retain moisture and prevent drought damage. Adds nitrogen to the soil.
  • On camping trips. Dust the ground where you intend to place your tent and camp area.
  • Antifungal properties
  • Dust under and behind appliances, in window sills, door thresholds and in attics and walls
  • Used in seed and grain storage to keep dry and mold free indefinitely. Will allow seeds to sprout after years in storage.
  • Keeps fly larvae from developing in manure, noticeably reducing the fly population. (Neighbors no longer complain about flies)
  • Sprinkle the ground liberally on and around tree trunks, also may be painted with a mixture of DE and water.

  • Debbie Osborne's Animal Deworming Recipe

    Debbie Osborne told me of a natural parasitic that she uses with both her goats and horses.


    She says, “As a rule of thumb, I use 1 cup of the powdered herbs to 2 cups of the cut herbs, except for the Cloves and the D.E.” The most crucial ingredients in the recipe are marked by an asterisk (*).

    HOW TO USE IT...

    Sprinkle the mixture on their feed in the morning and evening for 7 days straight. A mature goat gets about 1 tablespoon in the morning and evening. A mature pony gets about 1/4 cup in the morning and evening. A mature horse gets about 3/4 cup in the morning and evening. Use slightly smaller amounts for offspring.

    "Just a quick message to say that I love your site and your products. I am a naturopathic vet in training and read your animal worming recipe with interest (it is very similar to one I use myself) but thought that you might add a note for horse owners. Black walnut hulls can contain a fungus which is deadly to horses, so it isn't always advisable to feed it to them, or pasture them under black walnut trees for that matter. If the infection is caught early enough it is sometimes treatable, sometimes not.
    "It should be noted that black walnut does not always contain this fungus. It just depends and there is no good way to tell if it does or doesn't. Everything else in the recipe is perfectly safe for horses. The dangers of the fungus apply ONLY to horses. The recipe in its enitirety is perfectly safe for other animals. Thanks so much for all your great work." -Anna
