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 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.

    • 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 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.

  • 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.

    • 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 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.

  • From Lindsay at 5/25/13 7:47 AM
    • I see that most of the posts on here are from people using for everything buy vegetable gardens. I know you say it is food grade and safe to use around gardens. If that's the case, why aren't more people using it for that purpose? The idea makes sense to me and I have a big problem with slugs/snails and earwigs. My garden is organic and would like to keep it that way.
      Just a little skeptical...
    • Hi Lindsay,
      DE is safe and effective for use in gardens. We use DE throughout our organic vegetable gardens for slug and earwig control, and especially for our persistent pests - sow (pill) bugs. DE is less effective when it gets wet, but after it dries out it regains full effectiveness. We have been using DE in our gardens for over 20 years, and there is no reason to be skeptical - it is safe, organic and inexpensive for insect pest control - and very effective!

  • From M. Summers at 6/24/13 11:59 AM
    • We just found we have bedbugs this DE stuff sounds pretty good... I have indoor dogs will this cut up thier feet
    • No. DE will not irritate your pets' feet. DE is harmless to pets.

  • From Tj at 7/17/13 6:16 PM
    • When sprinkling on carpet ,you must let it set for couple days to help rid of fleas. But what if I have a 8month old baby who crawls around do I need to be careful of the baby getting this on him and what about petting your pets and getting on your hands?
    • Diatomaceous Earth will not harm your baby if he comes in contact with it, and it is also safe for pets. If you get DE on your hands it is no problem, you can just rinse it off.
      DE is a fine powder, like talcum. You should not apply it too thickly on a carpet or any area where it might rise up into the air when disturbed. Any fine powder can be an irritant to the lungs, even more so with a baby.
      We recommend applying DE in areas which have lower traffic, such as under the couch, behind appliances, furniture and places the vacuum cleaner doesn't reach.
      If you have a problem with fleas on the carpet, we suggest you augment your DE treatment by using an electric flea trap in the suspect areas.

  • From Deborah at 8/2/13 2:14 PM
    • Have read each one of the posts, but have not seen anything related to CHINCH BUGS, found in our clover lawn, killing it. Does DE work on Chinch bugs?
    • Yes. DE is an effective measure you can take to control chinch bugs in your lawn. DE acts as an abrasive. It cuts the outer layer of the chinch bug's body causing it to dehydrate and die.
