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.

  • From Julie at 6/3/14 3:21 AM
    • Does Insect Dust contain any trace of crystalline silicon dioxide? I've read that some diatomaceous earth insect repellent products contain a small amount and that it can be harmful to pets if inhaled.
    • Food grade DE is safe for pets. "Pool grade", DE however, is calcined, meaning that is treated with very high heat. This turns the silicon dioxide that is present in the DE into crystalline silica. Pool grade diatomaceous earth has more than 1 percent crystalline silica. Food Grade Diatomaceous Earth, on the other hand, has less than 1% crystalline silica and is not calcined.

  • From Courtney at 6/17/14 2:17 AM
    • If I sprinkle this on my carpets after vacuuming is it safe for me to walk around barefoot in my place until the next time I vacuum it up, or should I wear something to protect my feet until I no longer need to use this product?
    • You can walk barefoot on the carpet after dusting with DE, you will not even feel it. DE looks and feels like talcum powder.
    • Do you find this question helpful?  Yes  No
  • From Amber at 6/26/14 6:44 PM
    • Since DE is also microscopic, does it work on chiggers? We cleared out an area of our "north 40" and now have a tire swing on a large tree for our toddler. When our there recently, we all got eaten up by chiggers, so we want a natural remedy that will knock them out, but still be safe enough for our daughter, dogs, and surrounding plants.
    • Yes, DE is an effective treatment which will kill chiggers. Broadcast it in areas where you see chigger activity; for effectiveness they need to come into direct contact with the DE. After rain it will diminish in effectiveness, but this will be restored as it dries. Try to locate the DE where strong winds will not displace it. It is better to place DE in a thicker amount in selected areas than with a thin application broadcast widely.

  • From Dee at 7/10/14 1:02 PM
    • I live in an apartment near a lake on the first floor and I have earwigs all over my porch. I have an 8 month old baby and was wondering if this is a safe product to use right outside my front door.
    • Yes. DE is a good solution for your situation. It is safe if the baby comes into contact with it, it will not harm or pollute the lake water, and it is effective against earwigs.
      DE is not a spot killer. It will take a few days before you notice the earwig population reduce. Be persistent and reapply DE if you think it needs it (e.g. if it rained and washed off some of the DE). Over time, you can reduce the earwig population to near zero.
    • Do you find this question helpful?  Yes  No
  • From Tammy at 7/18/14 8:53 AM
    • Is this brand food safe?
    • Yes. This is food-safe DE.
    • Do you find this question helpful?  Yes  No
  • From sherry at 8/25/14 10:58 AM
    • The ants just walk around the diatomaceous earth. What can I do?
    • DE is not a spot killer. The ants which have walked over the DE will soon die of dehydration. They will also have tracked the DE to their nest where other ants will meet a similar fate.
    • Do you find this question helpful?  Yes  No
  • From Katie at 9/23/14 12:48 AM
    • I'm using DE to treat a cockroach issue in our house, and while I see it's pet safe, will it have any negative effect on clothes in my drawers or shoes around the bed.
    • No. DE will have no effect on your clothes, shoes, or any other items around the bed.
    • Do you find this question helpful?  Yes  No
