Use Insect Dust to eliminate crawling insects around your home. Diatomaceous earth comes in the form of a chalky powder, and is the natural fossilized remains of diatoms, a type of hard-shelled algae. Diatom particles are very small and sharp – but only harmful to the small exoskeletons of insects. Because it is a light dust, diatomaceous earth easily clings to the bodies of insects as they crawl over it. The tiny diatom particles then cut into the waxy coating of insects and they dry out and die of dehydration within 48 hours. Insects cannot become immune to its action, as it is a mechanical killer – not a chemical one.

Food Grade Diatomaceous Earth is an all-natural product that is so safe it can be sprinkled into your vegetable patch, or rubbed right into your dog's fur.

What insects does it control?

  • Fleas
  • Ants
  • Ticks
  • Cockroaches
  • Bed bugs
  • Silverfish
  • Beetles
  • Earwigs
  • Grasshoppers
  • Spiders
  • Aphids
  • Spider mites
  • House flies
  • Tomato hornworm
  • Slugs

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 floor, carpets and bedding in and around pet's sleeping areas, as well as surrounding baseboards, cracks and crevices. Safe to use around your pets - it can be rubbed right into your dog'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, along baseboards, and wherever else silverfish are found.

Carpet Beetles

Dust along baseboards, carpet edges, under carpet, furniture and inside closets.

Outdoor Use:

Lightly coat a thin layer of diatomaceous earth on areas where insects are found such as patios, window sills, door frames, foundations, sewer pipes and drains. Apply as a barrier around plants, trees and garden beds. Diatomaceous earth is most effective when kept dry. For best results, reapply 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.

Slugs and other garden pests

Apply as a barrier around plants and garden beds. Reapply after rain. Any diatomaceous earth that washes into soil will continue to benefit your garden, since it acts like vermiculite in retaining water for future slow release. Insect Dust is 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 disease. Set a "dusting box" of DE in the corner of the coop and chickens will continually apply themselves with DE. This will reduce or eliminate lice within a few days.

Insect Dust Diatomaceous Earth comes from a naturally occurring freshwater deposit in the USA. Our diatomaceous earth is uncalcined amorphous silica, which is harmless when ingested and commonly used in animal feed.

Insect Dust Diatomaceous Earth is certified for organic use by the Organic Materials Review Institute (OMRI).

The FDA lists Diatomaceous Earth as "Generally Recognized as Safe".

Environmental Health Coalition refers to Diatomaceous Earth as one of the least toxic insecticides for household pest control.

Note: Food grade diatomaceous earth should not be confused with "Pool Grade" diatomaceous earth, which is treated with heat, causing the formerly amorphous silicon dioxide to assume crystalline form. Do not use pool-grade diatomaceous earth for pest control.

    • I heard this also is a wormer, for chickens and goats, is this true?
    • Yes, diatomaceous earth can be used as a wormer for animals.
    • Do you find this question helpful?  Yes  No
  • From Lauren at 9/22/12 8:28 PM
    • I have seen about bearded dragons and lizards, but I am curious to know if DE will harm tree frogs or toads. I'm planning to use it in the house on carpets and cats for fleas, but would LOVE to pour some into the ant mounds and garden. I am a frog lover, though so I would be devastated if I killed them instead of the ants and tomato worms!!
    • DE will not harm tree frogs or toads. It is fine to use for the ant mounds or in your garden.
    • Do you find this question helpful?  Yes  No
  • From Ann at 9/24/12 5:08 PM
    • A commenter on the natural flea control article on Mother Earth News says that DE will scratch human's or animal's eyes if it gets into the eyes. The commenter also says that water will not eliminate the scratching. Is this true?

      Also, is it okay to sprinkle DE on a sofa? My dogs sit on the sofa frequently, so I imagine that there are fleas in the sofa.
    • Diatomaceous earth is a dust, meaning that it is irritating to both eyes and lungs. For this reason, you want to avoid placing it in areas where it may be tracked up easily or may be blown into the air. It is safe to use on your sofa.

  • From gilbert at 9/25/12 6:05 PM
    • will the diatomaceous earth work on termites?
    • Yes, the diatomaceous earth is effective against termites.

  • From Shannon at 9/30/12 8:52 PM
    • I have been dealing with a flea investation with my 10 yo dog now for over a month having tried just about every way to get rid of them and I am still having problems. As my dog has free roam of my entire house can I sprinkle this down all over my carpets and sofa and leave for a few days before vacuuming? I have read you suggestion at putting it in corners, etc., but I don't think that will be enough. So what is your recommendation in my case.
    • Yes, you can broadcast DE widely for short term maximum exposure. This will impact the resident flea population. But after you vacuum, you will need to reapply DE to discreet areas, such as corners and beneath the couch to address the emerging fleas hatching from existing eggs. Since you have a dog, it is recommended that you keep some DE in suspect locations permanently.

    • can food grade daiatomeos earth be used against termites and how can it be used against them.
    • Yes, diatomaceous earth can be used against termites. You want to spread it in areas where you are having issues with termites. It can also be mixed with water and sprayed into hard-to-reach areas, and will be effective once it dries.
    • Do you find this question helpful?  Yes  No
  • From Amey at 10/17/12 12:24 PM
    • I have a couple of questions about this product. Both my cat and my dog have fleas (the cat is worse than the dog). The dog was treated with Frontline, but the cat with Hertz. I swear once I applied the Hertz (WORST PRODUCT I EVER PURCHASED), he started acting differently (he twitches/has painful sounding meows/open cuts on his neck/etc), and his fleas became super fleas. They are big and they are everywhere!!!!

      First question: Will this take care of major infestations or do I need to take them to the vet and call an exterminator?

      Second question: Can it be used if my cat has an open wound?
    • For major infestations you may need to call a pest control specialist to your home.

      For moderate infestations you can try an electric flea trap.
      This will give you an indication of the scale of your flea problem.

      DE is effective as a long term deterrent for fleas as well as other household insects. It will reduce the population and will kill emerging eggs which can lay dormant in your home for months.

      DE can be used if your cat has an open wound, but you are advised to apply it lightly in one area to see if your cat has any reaction. Your cat may be hyper-sensitve right now due to the other treatment, so caution is hte best approach.

    • I have heard from other sites that de has great health benefits is your product the kind a human can injest for those benefits?
    • Diatomaceous earth is used primarily for insect control around the home and garden. However, some people do consume it for health benefits. Because this diatomaceous earth is food grade, it is completely safe to ingest.

  • From kate at 11/10/12 12:09 PM
    • Is this product safe to use in areas that small children will be, couches, rugs. etc.? Childern are ages 5 and 2..
    • Insect Dust (Diatomaceous Earth) is safe for use around children and pets. You could sprinkle some under the cushions of the couch and on parts of the rug that are under furniture. However, DE is a fine powder and it is not advisable to apply it in active play areas, since the dust would get stirred up.
      We advise applying DE in discreet areas such as behind furniture along walls, behind the refrigerator, above cupboards, beneath beds, etc. where people don't usually go and the vacuum doesn't reach.
    • Do you find this question helpful?  Yes  No
  • From Heather at 11/11/12 5:39 PM
    • We used this product in our home. It made everything dusty and a mess. But seems to be working, My issue is that it's still dusty here.. The dust has settled but it's still on things. My 2 year old daughter will be ok to be inside right?
    • Yes, the diatomaceous earth is food grade so it is completely safe to use around the home. Because it is a dust it can irritate the lungs, so you want to avoid tracking it up when walking around.
    • Do you find this question helpful?  Yes  No
