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. Insects cannot become immune to its action, as it is a mechanical killer – not a chemical one. 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.

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

What Insects Does It Control?

  • Fleas
  • Ants
  • Ticks
  • Silverfish
  • Cockroaches
  • Bed bugs
  • Carpet beetles
  • Spiders
  • Earwigs
  • Spider mites
  • House flies
  • Slugs and snails

For Indoor Use:

Lightly coat a thin layer in areas where insects are found or may hide, such as 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.

You can leave the 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 for a few days. It is still safe to sleep in your bed even while the dust is present.


Lightly dust in and around kitchen and bathroom plumbing, along baseboards and wherever else silverfish are found.

Carpet Beetles

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

For Outdoor Use:

Lightly coat a thin layer of diatomaceous earth on areas where insects are found, such as patios, door frames, foundations, sewer pipes and drains. Apply as a barrier around plants, trees and garden beds. For best results, reapply the Insect Dust after heavy rainfall.


Thoroughly dust areas where flies frequent, such as livestock pens and kennels. It can be applied to livestock coat as an insect repellent/contact insecticide. DE can also be added to the food of pets and livestock. The DE helps as a de-worming 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. This is an effective method for fly control, especially on farms and homesteads, and in outdoor areas where animals are present.

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. Our diatomaceous earth is OMRI listed for organic use.

Diatomaceous earth will not harm worms or any of the beneficial microorganisms in the soil.

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.

This Food-Grade Diatomaceous Earth is uncalcined amorphous silica, which comes from natural freshwater deposits in the USA. The freshwater naturally occurring diatomaceous earth deposits that are designated Food Grade by the FDA have less than 1% crystalline silica. These deposits are primarily amorphous silica which is harmless when ingested and is commonly used in feed and food industries. Insect Dust is certified organic by the Organic Materials Review Institute.

Insect Dust is registered as an insecticide with the EPA, so it is required to have a generic health warning on the bag, despite its safety.

Environmental Health Coalition refers to Diatomaceous Earth as one of the least toxic insect controls on their "Home Safe Home" fact sheet about safe household cleaners and indoor pest control.

Professor Stuart Hill at McGill University describes Diatomaceous Earth as non-toxic and feeling like talc when you touch it. He says that if you are going to apply large quantities, you should wear a face mask to avoid inhaling it. However, he mentions that inhaling common road dust is probably more harmful than inhaling Diatomaceous Earth.

Please note that food-grade diatomaceous earth should not be confused with "pool grade" diatomaceous earth. Diatomaceous earth used in pool or water filtration contains DE that has been chemically treated and heated making the silica crystalline which is a dangerous respiratory hazard and harmful to the health of humans and animals.

  • From Elizabeth at 5/22/17 6:53 AM
    • Is your product safe around bees? I have a bee hive and my yard is organic but I have roaches outside that apparently love my flower beds due to the moist cool soil. They seem to be multiplying every year due to our mild winters. I'm looking for a pest solution that won't harm my bees. Please advise. Thanks!
    • If you keep the insect dust on the ground and not on your flowers, bees will be unaffected. Roaches will perish because they have to crawl through the soil with insect dust on it.

    • When applying in a soultion, how much earth should you use to water in a 32 oz bottle
    • We recommend using a ratio of 1 tablespoon of our Insect Dust per 32 oz of water, or 4 tablespoons per 1 gallon of water.

    • How wide a band should DE be applied around outside perimeter of house and how heavily?
    • Insect Dust Diatomaceous Earth kills all insects it come in contact with it, including bees. You need to be conscious of this, especially when applying around the garden. Outside it is best to apply strategically where it is going to come in contact with the insects causing you trouble. Inside it will be best to apply it under furniture or along baseboards, somewhere it will not get kicked up or blown around. The dust does not expire, but when it looks like the dust has dispersed you can reapply. Some ways to spply it are using a spoon, fingers (it is chalky so you may want to wear gloves), flour sifter, powder shaker, ect. A light perimeter dusting is a good deterrent, if see a clear path they are using you can use a more generous amount to block it.

  • From Jennifer at 7/28/16 10:25 AM
    • I am looking into purchasing this for my company property. We have an ant, roach, and silverfish problem in all our buildings. The owner is against chemicals so I am hoping this can be our solution. What ratio should I use to create a water solution that I can spray around the buildings during work hours? What places should I avoid? Will mixing it with water reduce its effectiveness? How often will it need to be reapplied?
    • You should not mix Insect Dust Diatomaceous Earth with water for application, it will become a paste. It is also ineffective when wet, when it dries out it will work again, however if it has clumped it needs to be redispersed. Insect Dust does not "expire" but if it gets blown/swept up so you will need to reapply. You want to put it under furniture, behind couches, along the wall, or on the top of cupboards. To spread it you can use something like a powder shaker, your fingers or purchase a dispensing tube. It is dry and chalky, so if you use your fingers you may want to wear gloves. Some people report the dust irritating their breathing, as any dust would, so if someone has sensitive breathing maybe apply when they are not around but we have never had any issues with it irritating people.

  • From Bill at 7/18/16 10:44 AM
    • I am looking for something to permanently kill off a flea infestation with a product that won't be harmful to my granddaughter, who has leukemia. The pet has been removed. I am looking to use in a ground level apartment with carpeted living room (apx 12x14) master bedroom (apx 10x12) and 2nd bedroom (apx 8x10)

      Thank you
    • For flea infestations you can try a two pronged approach that is safe and entirely nontoxic for your family and especially for your granddaughter.

      The Electric Flea Trap should be placed in the vicinity of the most flea presence. Use one or several of these traps depending on the extent of infestation. Keep using them until there are no captures.

      Apply diatomaceous earth (DE) strategically in areas which the vacuum will not suck it up. Place DE beneath furniture, in corners behind appliances, especially moist areas. Place DE beneath the bed on the ledge of the frame. Put it in pet bedding. DE does not expire so keep it in place permanently. Reapply if it gets spread out, disturbed or covered with dust.

      DE is not an instant killer, but it is ideal for long term flea control. Do not bother sprinkling on your carpet, it will not last long there since it is constantly disturbed. But put it along the perimeter of the carpeted area where it is not visible.

      You may eradicate the fleas but the eggs can remain viable for up to a year, so DE should remain in place even if you think the fleas are gone.

      Good luck!

    • Will DE cause problems for friendly creatures in the garden like earthworms and bees?
    • Hi Nancy,

      Thanks for your email! Diatomacous Earth is harmful to the exoskeletons of insects, which includes bees. If you can, avoid using it on or near blossoms. Earthworms have endoskeletons, so it will not cause them harm.

  • From Adi at 7/14/15 6:51 AM
    • I have tons of little green leaf insects in my garden, is your product good against them too? We do have squirrels and deer coming to our yard which I would like to keep safe. I understand the product is safe for wildlife creatures big and small, only harmful for insects?
    • Yes, the DE is harmless to your deer and squirrel visitors. It is safe for all garden applications, but to be effective the insect must contact it. Typically, one lays a small line of DE that insects will cross, or a small circle around the perimeter of plants. You can also dust the plant leaves with DE to ensure the green leaf bugs are exposed, but once they're gone give the plant a rinse with water so the leaves have full access to sunlight.
      Bear in mind that DE is less effective when wet. (It will become effective again once it dries.) So some persistent problem areas may need reapplication.

  • From Linda at 7/3/15 8:36 PM
    • Beatles are devouring my garden. Is it safe to dust directly on vegetable plants?
    • Yes, DE can be applied directly to your vegetable plants. It is better to have a small pile or line that bugs will cross, than a thin sprinkling over the plant leaves. The thin dusting doesn't hold up as long in weather. If the beetles are flying on to the leaves then you have to dust them, but if they are coming from the ground then apply small lines around the base of the plant.

  • From Vickie B at 6/21/15 8:20 PM
    • I have C.O.P.D. Will using DE add to breathing problem? Want to use to get rid of roaches.
    • DE is a fine powder which could, if used incorrectly, could contribute to airborne irritants for people with breathing difficulties. DE should be placed in discreet areas of your home where bugs will contact it, but the vacuum or general house traffic will not disturb it.
    • Do you find this question helpful?  Yes  No
  • From Caroline at 4/8/15 9:36 AM
    • Will d/earth control and kill carpenter ants?
    • Yes. DE is effective against ants, including carpenter ants. DE has nomammalian toxicity and may be blown into nests and cavities to kill the ants.
    • Do you find this question helpful?  Yes  No
