Use Insect Dust to eliminate crawling insects around your home. Our natural diatomaceous earth comes from the natural fossilized remains of diatoms, a type of hard-shelled algae. Diatom particles are very small and sharp – but only harmful to the exoskeletons of insects. When insects crawl over diatomaceous earth, the tiny diatom particles cut into the waxy coating of insects and they die from dehydration within 48 hours. Insects cannot become immune to its action as it is a mechanical killer – not a chemical one.

Insect Dust is an EPA registered natural insecticide. Safe to use around your family and pets - it can be rubbed right into your pet's fur.

Insect Dust kills the following insects:

  • Fleas
  • Ants
  • Cockroaches
  • Bed bugs
  • Ticks
  • Silverfish
  • Beetles
  • Earwigs
  • Wood bugs (pill bugs)
  • Crickets
  • Spiders
  • Aphids
  • Spider mites
  • Flies
  • Stink Bugs
  • Tomato hornworm
  • Slugs

For Indoor Use:

Lightly coat a thin layer in areas where insects are found or may hide. For example: kitchen cupboards, behind and under appliances, baseboards, or drain pipes. For carpets, lightly sprinkle the insect dust over the carpet, and leave for 2-3 days before vacuuming.

Leave the insect dust in place until you no longer see any signs of insects in that area, at which point you can clean it up.


Thoroughly dust carpets and pet's bedding or sleeping areas, as well as cracks and baseboards. It can be rubbed into your pet's fur.


Take apart bed and dust joints and channels. Dust any hollow tubing and the interior framework as well as the mattress and all cracks in the room. Use a turkey baster or duster to apply clouds of the dust over the affected area. Leave the dust to do its job for a few days. It is still safe to sleep in your bed even while the dust is present.


Lightly dust under the sink, inside drawers, or along the baseboards, and wherever else silverfish are found.

Carpet Beetles

Thoroughly dust along baseboards, carpet edges, under furniture, carpet, and rugs, and in closets and shelving.

For Outdoor Use:

Lightly coat a thin layer where insects are found. Areas such as patios, porches, window sills, door frames, foundations, drain pipes, and pools. Apply as a barrier around plants, trees and vegetables gardens. You need to reapply insect dust after heavy rainfall.

Fire Ants

Sprinkle diatomaceous earth directly on the ant mound, or mix with water to saturate the mound. It can also be sprinkled along ant trails. The ants will track the DE back to their nests where the colony will be exposed to its abrasive action.


Thoroughly dust areas where flies gather (livestock pens, kennels, corrals etc.). It also can be applied to livestock coat as a contact insecticide. DE can also be added to food for pets and livestock. DE helps as a deworming agent for livestock, and it ends up in their dung. Flies lay eggs on the dung which hatch into maggots, which are then killed by the DE. Effective method for fly control, especially on farms and homesteads.

Slugs, earwigs, and other garden pests

Apply as a barrier around plants and garden beds. For best results, reapply after rain. If diatomaceous earth washes into the soil it will continue to benefit your garden by retaining water for future slow release into the soil. OMRI Listed for use in organic agriculture.

Lice control for chickens

Lice are a common scourge around chickens and can lower their vitality resulting in fewer eggs and low disease resistance. Set a "dusting box" of DE in the corner of the coop and the chickens will continually apply themselves with DE. This will reduce or eliminate lice within a few days.

Environmental Health Coalition refers to Diatomaceous Earth as one of the least toxic insecticides for household pest control. As an EPA-registered insecticide, it is required to have a generic health warning on the label, despite its safety.

Please note: Insect Dust Diatomaceous Earth should not be confused with "Pool Grade" diatomaceous earth for pools or water filtration systems. Pool Grade DE has been heat treated, causing the formerly amorphous silicon dioxide to become crystalline, and it is not safe or effective for household pest control.

  • From Jacqui at 3/8/11 7:43 AM
    • Hi, just popped in from New Zealand and was wondering if you had a price (currency conversion) for the DE and USP for delivery to NZ? Really interested in your product.....
    • Hi Jacqui,
      We are sorry but we are unable to ship DE overseas. This is due to the cost of shipping, and our warehouse is not set up to do the paperwork involved. You may have a friend in the US who can receive the DE for you and forward it to you, but we are unable to do this ourselves.

  • From Lauren Katz at 3/1/11 7:27 AM
    • I have a tea cup yorkie, and a 15 pound cat. I would very much like to use this product on and around the area of my Tea Cup dog. However she is only 3 pounds. And does lick herself. Also.... my cat grooms herself frequently....

      so, is this safe for the teacup?
    • Yes, our Insect Dust (Diatomaceous Earth) is completely safe for the Teacp Yorkie and the cat. Licking the diatomaceous earth is harmless, as this is food grade DE.
      Just sprinkle the DE in areas where insect pests frequent, and if possible, sprinkle it where the vacuum cleaner will not suck it up too quickly.

    • I have been told that D.E. is also good to use around chicken pens. How would be the best way to apply?
    • Insect Dust (Diatomaceous Earth) can be sprinkled inside the coop, especially in crevices or cracks which harbor mites. You can also sprinkle some DE in nesting boxes inside the coop. Over time, the chickens will displace the DE as they scratch the bedding in the coop, and some DE will be buried. You will need to reapply occasionally, depending on the type of bedding in your coop.

    • Being food grade, does this mean it will be safe to use in my vegetable/fruit garden? I have a terrible problem with ants in the garden.
    • Hi Jan,

      Insect Dust (Diatomaceous Earth) is safe to use in your vegetable garden. It is safe for you and for your plants.

      For best results, you need to understand how DE works. When insects come into contact with DE, their exoskeleton becomes scratched by the microscpoic sharp egdes of DE, and soon they dry out and die. So you want to place the DE in a spot which the insects will cross. In outdoor locations such as a garden, the DE will be most effective when dry. You may want to reapply the DE after a rain. Strong wind may also blow away some of the DE, so try to put it in a place where there will some wind protection.

      We have used DE at our home for years, both indoors and outdoors, and have found it to be the single best nontoxic insect control product we have used.

  • From Melis at 11/23/10 4:16 PM
    • Hi,

      The website indicates that this product is safe for pets.
      My 3-week old kittens are infested by fleas. Would it be safe to apply this product on them? What about on the mother who is with the litter all the time?

    • Hi Melis,
      Yes, diatomaceous earth is completely safe for your cats, even the young kittens. You can rub DE into their fur, and also the mother cat's fur. Sprinkle it in and around their bedding.
      DE is especially good at long-term control of fleas, and other insects as well. The insects outer skin is scored by the DE which leads to their dehydration and death, usually within a few days of coming into contact with the DE. Results are not immediate.
      In your case, since there is an infestation, you may need instant as well as long-term control of fleas. I suggest you get one of our electric flea traps and set this beside the litter. This will decrease their numbers quickly, and the DE will finish the job and keep the fleas away over time.
      Also, cats will continue to bring in fleas, so it's a good plan to sprinkle DE in areas where the cats frequent.
      We don't have cats anymore, but even now we sprinkle DE in all the rooms of our home to keep the bug population down. I can speak from personal experience to the effectiveness and safety of diatomaceous earth.

  • From Cathy at 9/29/10 5:42 PM
    • Does this package of diatomaceous earth have an expiration date?
    • Hi Cathy,
      Diatomaceous earth does not have an expiration date. DE is inert, the skeletal remains of diatoms, which have been around for millenia.

  • From Susan at 9/28/10 6:14 PM
    • How do I apply this to my dog for safe and effective flea control? Do I rub it all over his fur or do I put it on his skin? Is it effective if I just put it on the nape of his neck like the chemical flea medications? I am currently using Advantage which works, but it makes him smell bad and I don't feel good about putting poison on my dog.

      Also, I was wondering how often does this need to be reapplied for it to be effective?

      Thank you!
    • You can rub diatomaceous earth into your pet's fur, and sprinkle it around your pet's bedding. Reapply to the fur if your dog gets wet or if any flea activity is present.

  • From Paul at 8/30/10 6:55 AM
    • Is there a way of mixing this with water so it can be sprayed via a garden sprayer??? Paul in Fayetteville, N. C.
    • Diatomaceous earth is a fine powder and should be able to used as a spray, but we have not done this ourselves. For garden applications, we broadcast DE by hand. This way we can add more in trouble spots and not apply any to areas where it sin't needed.

  • From L. Hannon at 8/3/10 8:11 AM
    • My cats have fleas. I have used advantage on them- and it seems to be working. Can I use this product on my cats even though they have been treated with advantage? Also- I only have carpet in one room- the rest is wood floors. I think the worse place is under my bed, but I can't move the bed. How can I treat under the bed? Thank You
    • Yes, you can apply diatomaceous earth to your cat's fur, or around the home, even though your cat has been treated with Advantage. In fact, it's a good idea to use DE as a secondary, and more lasting, preventive treatment against fleas.

      If you cannot move the bed, use a long spoon or any method to sprinkle DE in spots. In our home we sprinkle DE along the baseboards where no one can see it. When we vacuum, we try to avoid these spots. After a few weeks, we will vacuum more thoroughly and then reapply the DE in the same spots. Our home has been free of fleas and other insect pests for yers.

  • From Aaron at 7/20/10 3:08 PM
    • I have a major roach infestation in my house. The roaches climb up the walls. How do I get around this problem?
    • Diatomaceous earth is effective for roaches, but it will take some time for you to see results if you have a large infestation. Even if you take other measures to control the roaches, keeping some Insect Dust sprinkled in areas throughout your home will help keep the population down over time.
