Use Insect Dust to eliminate crawling insects around your home. Our 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 die of dehydration within 48 hours.

Insects cannot become immune to diatomaceous earth. It is a mechanical killer – not a chemical one.

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 is registered with the Environmental Protection Agency for use as an insecticide. Environmental Health Coalition refers to Diatomaceous Earth as one of the least toxic insecticides for household pest control.

Note: Insect Dust Diatomaceous Earth should not be confused with "pool grade" diatomaceous earth used in filtration. Pool grade DE has been heat treated, turning silicon dioxide into crystalline silica, which is not suitable for household use.

  • From malorie at 5/19/13 9:23 PM
    • I have a one year old son and he is barely walking is sit safe for him to be around?
    • Yes. Diatomaceous Earth is nontoxic and will not harm your son even if comes into contact with it.

      However, DE is a fine powder, similar to talc, and any fine substance can cause irritation to the respiratory tract of people with allergic sensitivities. Use your good judgment - place small lines or teaspoon size amounts of DE in strategic locations where bugs will come into contact but your son will not. For example, apply DE to the tops of cupboards, beneath appliances, behind the couch, under the bed and similar locations around your home.

    • Will diatomaceous earh hurt my box turtle?
    • Now this is a question we've never been asked!
      We have no empirical evidence that DE will not harm your box turtle, but we are quite confident that your turtle will be safe if he/she comes into contact with DE.

  • From Jenn at 4/12/13 11:29 AM
    • How often do you recommend applying DE to the dog. With products like Frontline in areas of heavy flea and tick problems it recommends applying once a month all the time. Is that the case with DE as well?
    • You could apply DE more often than once a month if conditions warrant. If the dog gets wet, for example, then yopu may want to reapply DE after dry. You should also dust some DE into the dog's bedding, house, or areas where the dog frequents most often.

  • From Diana at 2/21/13 3:45 PM
    • We had a problem with white footed ants. Will this work based on the habits of this pest?
    • Yes, DE is effective at controlling white-footed ants.The key to getting good results using DE is strategic placement. If there are white-footed ants in your home, they will use the same trail repeatedly from their colony to a food source. By observing the ant activity you can figure where to lay a line of DE which intercepts their trail. Look for other likely places and spoon out other small lines of DE.

      White-footed ant colonies are large, so you will need to be persistent in applying DE over time. Ideally you will also locate and seal ant entry points. It is also a good idea to trim or pull shrubs and tree branches away from the outside walls of your house.

    • This is in the context of cockroaches in an apartment. How to apply the dust? By hand? Thin coating or thick? Is the dust to be removed or to be allowed to remain?
    • The goal is to get the insect to crawl through the DE. For roaches, use a teaspoon and spoon out a small plie on top of your kistchen cupboards, behind appliances or other suspect places. The DE can be out of sight and left there for some time. The pile does not have to thick, just a thin line will do. We leave DE in locations that will not be in the path of the vacuum cleaner, and in some areas the same DE has been in place for 6 months or longer.

  • From Richard at 12/29/12 8:13 PM
    • How do you apply the dust in the house? Is there a shaker (like salt or pepper or baby powder) that can be purchased along with the insect dust?
    • We broadcast DE in the home using a teaspoon to set small mounds in discreet areas (that are not likely to be vacuumed) and out of the way of normal foot traffic. Over time these little piles get spread about and swept up, to be repaced. In our hoe, this cycling happens about 3 times a year.
      Be sure to apply DE on top of the cupboards as well as the usual suspect places.

    • 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.

  • 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.

  • From greene at 11/5/12 3:25 PM
    • 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 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.
