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 lacey at 8/10/12 3:03 PM
    • Hi i was reading this and it seems to sound like it works and im interested in trying it but is it safe for kids? I have a 14month old child and my two boxers are infested with fleas and so is the house and we hav tried everything nothing is working!! Can you clarify if its safe for kids thank you
    • Yes, the insect dust is food grade and so it is entirely safe to use around children.
    • Do you find this question helpful?  Yes  No
  • From dan at 8/4/12 8:18 AM
    • will de help with pine bettles? if so how to i apply? thank you
    • Yes, DE will kill pine beetles. The key to application is to leave DE in areas where the insects will walk across it or come into physical contact. In mature trees this is difficult., especially if infestation has already begun. For seedlings, DE can be sprinkled around the base and dusted over the seedling for protection.

  • From natalie at 8/1/12 4:32 AM
    • Can you put DE on your mattress for bed bugs or should you keep it on the floor near the walls and corners of your bed?
    • You could put DE on the mattress but it would be more practical to put it along the edges of the floor, corners and any cracks.
    • Do you find this question helpful?  Yes  No
  • From Ruth at 7/26/12 11:39 PM
    • We live in a very old building above a boiler room and are infested with brown recluse spiders. The main difficulty with killing theses spiders is that their bodies are high up off the ground so even the most potent insecticides are ineffective. Will DE work on these frightening pests?
    • Yes, the diatomaceous earth will effectively kill the spiders in your home. For best results, apply the diatomaceous earth anywhere that they regularly frequent. It can even be applied to walls using a large brush. As long as the spiders come into contact with the insect dust, it will succeed in killing them after a few days.

  • From Kelli at 7/21/12 1:16 PM
    • Was wondering when I put this on my cats and they clean themselves, is this safe?? Also, my one cat is 13 years old and has sensitive skin, is this safe for him??
    • Yes. DE is safe to apply to the fur of your cat and harmless to the cat if he/she licks it.

      For the cat with sensitive skin, it is prudent to apply DE to a small spot on the cat to see if it irritates the skin in any way. If there is no irritation then gradually enlarge the application area and observe the cat for any possible reaction.

  • From August at 7/20/12 7:56 PM
    • Can I put DE on myself?
    • You can put DE on yourself in terms of safety, but it would not be particularly effective in deterring insect pests. The DE takes time to be effective, since it kills the insect by scoring the carapace which dehydrates the insect. For personal protection, you would do better with Herbal Armor or similar insect repellents.

      DE is not a repellent. It is a nontoxic form of insecticide which is most effective over time. We leave DE in small piles about the house in areas where it is not visible. This keeps the insect population down and in some cases eliminates the insect population entirely.

  • From Cathy at 7/20/12 1:27 PM
    • Part 1-Will this product hurt my carpets?
      Part 2- It is hard to keep completly away from vents in most rooms as they do blow across the area. I have tried to work it in and under rugs as best as I can but will it still be blown in to the air?
    • Diatomaceous Earth is a dust, and should not harm your carpets any more than other dust that could be brought into your house from outside. As for the vents, you mainly want to avoid placing the dust directly around the vents so that a large amount of the dust is blown into the air. You should still be able to operate air conditioning or run fans in your house while the dust is spread out, especially if you have worked it into your rugs or placed it underneath them.

  • From Diane at 7/12/12 3:04 PM
    • Hi, I have seen some DE that is cut with something, is your DE 100% or is it cut with another product? Thank you.
    • The insect dust is 100% food-grade diatomaceous earth - it is not cut with any other products.
    • Do you find this question helpful?  Yes  No
  • From Karen in Ocala, FL at 7/5/12 6:45 AM
    • Does DE have any effect on flea eggs or larvae or any other stage flea? (I imagine it would have to be applied directly to an inanimate egg if so?) Also, my cat has lost his fur & has wounds from biting at the fleas... a lot of them, poor kitty! Could the DE aggrevate those wounds or burn if I accidentally got it in one? Thanks!
    • DE will not kill flea eggs, it works by scoring into the live flea. Once the eggs hatch the DE becomes effective/ This is why it's a good practice to keep DE in discreet areas ofd the home where fleas may occur, since the eggs can live many months even if the adult population is eradicated.

      It is not likely the DE will aggravate the cat's wounds, but you should try to keep the cat away from the DE so the wounds can heal unimpeded.
    • Do you find this question helpful?  Yes  No
  • From Jane at 7/4/12 10:00 AM
    • Can I use DE on baby goats? We have a tick and mite problem. They are 4 weeks old. Will DE help for flies on cattle?
    • Yes, diatomaceous earth is safe to use on baby goats and cattle. However, it is a mechanical killer and not an insect repellant. It will kill the flies that come in contact with it, but this process is not instant and can take a couple of days.
    • Do you find this question helpful?  Yes  No
