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 Jennifer at 8/24/11 10:34 PM
    • We have a cabin in the upper penninsula of Michigan, on an island. It is woodsy all around the cabin, but has a nice sandy beach. The problem is that we have ant mounds all along the edge of the woods onto the sunny sand. They are everywhere up and down the beach and the mounds seem to get bigger and bigger every year. I have even noticed that tons are crawling down a tree into one mound near the beach too. Some cottage owners have just accepted them, but they are getting on my nerves because I cannot enjoy sitting by the beach any longer. I want to kill them naturally so that no chemical will get into the lake or harm people/pets. I know this will be a process that needs to be done every spring/summer b/c the winters are harsh up there and the melting snow will wash away what we put out. Would I be successful to just shovel the ant hill into the lake? They need to be killed b/c I don't want them rerouted into the cabin.
    • I think your best defense is to secure your home as best as possible from the ants. This is achievable. The outdoor mounds may be beyond your control, since the mond is only the upper part of a network of tunnels.

      We also ahve a cabin in the woods, and we also have ant mounds in the ground right by our door. A few ant get in the house, but not often. We set out little piles of diatomaceous earth, the size of a teaspoon, in strategic areas along the ground floor of our cabin.. Every month or so we renew these piles since they get tracked off and vacuumed when cleaning the place.

      DE is not a spot kill product. It takes time for the process to work - the ants track it back to their colonies. Ant that come in contact will die within a couple days. Gradually the population diminishes. But we continue to keep some DE around even when we see no ants. It has been very effective, also for pill bugs and whatever else, and we used DE exclusively for insect pest control for many years.

  • From Kerri at 8/4/11 6:08 AM
    • I actually have 3 questions.
      1. What are the instructions for hardwood and tiled floors?
      2. We have a child care center and our outdoor summer campers appear to be bringing the fleas inside with them. How effective would this be considering we vacuum the carpets at least once a day during the week.
      3. What does it do to the flea larva and eggs?
    • 1. you can apply DE on the hardwood or tile floor, just put it in discreet spots where people will not walk on it or spread it around.
      2. DE must be applied where it will not be vacuumed. you can apply DE in corners or locations where the vacuum misses.
      3. DE kills living insects by scoring their exoskeleton and dehydrating the insect. It does not effect larva.

    • I am a wildlife rehabilitator and I am needing something very safe for the animals enclosures to control fleas and ticks. The fawns eat leaves and grass all the time. How safe is this product for this purpose?
    • Insect Dust (Diatomaceous Earth) is exactly the product you are looking for. It can be sprinkled in the animal enclosures and will not affect them. The fawns can safely eat grass that may contain DE, and they will not be affected. Yet the flea and tick population will be reduced, and if you keep at it, their populations can be eliminated entirely from the pens.

  • From Rose at 6/28/11 5:43 AM
    • I recently noticed my 3 poodles have fleas.. and my family is also getting bit by the pesky critters. Is this safe to sprinkle on wood floors and human bedding? Also, once sprinkled do I need to wipe it up? I need my house treated but I'm not sure if I can just sprinkle it any and everywhere?
    • You can sprinkle Insect Dust (Diatomaceous Earth) anywhere you suspect flea or other insect activity in your home. We put out small piles (one teaspoon) in places where insects go but the vacuum cleaner won't pick up - behind furniture, on top of cabinets, on the bed frame under the mattress, and similar places.
      It is safe to sprinkle on wood floors or human bedding.

  • From Marlene at 6/18/11 12:48 PM
    • Our neighbors walked away from their home. We are noticing cockroaches around the exterior of our property. We also have a lot of lizards which we do not want to hurt or kill. Do you think spreading the diatomaceous might harm the lizards in an effort to kill the cockroaches?
    • The diatomaceous earth will harm the cockroaches but it will not harm the lizards.

  • From Ed at 6/2/11 4:18 PM
    • Can this product be used on a beach for ants? Can it in any way cause harm to the fish or birds that are on our lake?
    • Diatomaceous earth can be used on a beach and will pose no threat of harm to any of the fish or birds. It is entirely safe to use in this application.
    • Do you find this question helpful?  Yes  No
  • From April at 5/8/11 6:58 PM
    • Is this Amorphous DE. or Diatomite DE? I read there are different types of DE and cannot find any specs on ingredients or type for this product? I understand one is known to cause cancer, can you clarify?
    • Amorphous DE is food grade, freshwater diatomaceous earth.
      "Pool filter" grade DE has been heated to the point ot melting, making it much more crystaline and abrasive. As a result it is irritating to lungs and other soft tissue, making it carcinogenic.
      The DE we sell is food grade, and safe for applications in the home, safe around children safe for use on pets, and safe for use in the garden as a slug repellent.

  • From Tabatha at 4/9/11 1:44 AM
    • We are having Carpenter Ant problems in our house, will the ants take this back to their colony killing it off or should we use something along with DE?
    • Carpenter ants will not carry DE back to their nests. DE will kill carpenter ants which come in contact with it, but the effect is not immediate. There are a few products on the market which contain boric acid, which will have some effect on the colony, but boric acid is a poison and needs to be handled with care. In some cases, products containing boric acid need to be applied professionally.

      We use DE exclusively for controlling carpenter ants. It has been effective over time.

  • From Katherine at 3/27/11 7:36 PM
    • I have a dog, cat and bearded dragons that roam free in the house, will this have any harmful effects on my lizards?
    • Insect Dust (Diatomaceous Earth) is safe for use around your house pets, including the bearded dragons.

      DE is the consistency of talcum powder. To an insect, the DE is abrasive and scores the exoskeleton, leading to dehydration and death. But to larger creatures, the abrasive particles are too small to cause irritation.

  • From Wanda at 3/19/11 8:06 PM
    • If I buy the 4.4lb bag is there an expiration date to when the bag must be throwed away if all is not used in two years?
      Or can it be used till gone?

      I'm interested because we are being invaded by tiny ants that we can't find where there coming from. My son's 5th wheel trailer is more invested that us.
      I'm all for natural since we have a 10 Jack Russell Terrier.
    • There is no time expiry on Insect Dust (Diatomaceous Earth). You will not have to throw away any unused DE because it remains viable in storage over time. It will be effective against your ant problem.
