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 Debbie at 5/30/12 2:56 PM
    • How much do you add to the pets food?
    • This will depend on the size and type of your pet. Here are some estimates:

      Pets less than 10 lbs: 1/2 tsp to 1 tsp every day
      10-19 lbs: 2 tsp every day
      20-50 lbs: 1 TBs each day
      50-100 lbs: 2 TBs each day

      Particularly small pets, such as hamsters or gerbils, should get 1/4 tsp each day.

  • From Alice at 5/31/12 3:29 PM
    • I have a lot of slugs this year, after a couple of years of good control with bait, DE, and hand picking. I also have lots of plants to protect in my woodland garden. How do I apply DE adequately and efficiently for this application? Glad I found this site. I no longer feel like I need to climb into a hazmat suit to work with DE!
    • To apply the food-grade diatomaceous earth directly to plants, it might be best to mix the insect dust into a solution of water and spray the plants directly. The diatomaceous is most effective when it's dry, but this is likely the easiest way to coat the plants without making a mess. We also have the dispenser tube available, which allows you to control where and how much diatomaceous earth you are applying. You can find more information about that here: . Finally, if you have any old baby-powder shakers, those work well for spreading the diatomaceous earth on your plants and evenly throughout the garden.

  • From Paula at 6/2/12 8:29 PM
    • I have pet parrots and I know their respiratory systems are much more sensitive than other animals. I'm leary about using anything around them. Is DE safe to use around parrots?
    • DE is safe to use around pets. However, if you intend to use DE in close proximity to the parrot, e.g. in the cage, then it is recommended to try a small smaple at first and observe the bird for a week before adding more.

  • From Cassandra at 6/7/12 10:49 AM
    • Would like to know if it is safe to turn on air conditioner or fans after applying DE to carpet? My house is all carpet and that is fixing to change after rennovations. I was concerned about the dust floating about. It smells almost chalky in here. I suppose that is normal?
    • While it is safe to use diatomaceous earth in homes with air conditioning, you should avoid placing it near vents and fans, as the dust should not be inhaled.
    • Do you find this question helpful?  Yes  No
  • From Stephanie at 6/14/12 7:58 PM
    • We are having a flea problem. I'm looking for natural ways to deal with the problem as I have an 11 month old that crawls all over our floors. We have already tried a natural spray, but it seems to only work for one day and then he and my husband end up with bites again. Is your product safe for infants and how long after application would you say it's safe to allow him back on the floors?
    • DE is safe for infants when used in the home. DE is a fine powder, so it can be a lung irritant if inhaled directly and in some quantity. But you should locate DE where it is not readily accessible by an infant. We put DE behind furniture, on top of cupboards and in other discreet locations. This also keeps the DE out of reach of the vacuum which would suck it up.

      DE is not an instant overnight control for insects. It has a cumulative effect, so allow a week or so before you begin to evaalutate its effectriveness.

      Here is more information which may help you:

  • From Jane at 7/4/12 10:00 AM
    • Can I use DE on baby goats? We have a tick and mite problem. They are 4 weeks old. Will DE help for flies on cattle?
    • Yes, diatomaceous earth is safe to use on baby goats and cattle. However, it is a mechanical killer and not an insect repellant. It will kill the flies that come in contact with it, but this process is not instant and can take a couple of days.
    • Do you find this question helpful?  Yes  No
  • From Karen in Ocala, FL at 7/5/12 6:45 AM
    • Does DE have any effect on flea eggs or larvae or any other stage flea? (I imagine it would have to be applied directly to an inanimate egg if so?) Also, my cat has lost his fur & has wounds from biting at the fleas... a lot of them, poor kitty! Could the DE aggrevate those wounds or burn if I accidentally got it in one? Thanks!
    • DE will not kill flea eggs, it works by scoring into the live flea. Once the eggs hatch the DE becomes effective/ This is why it's a good practice to keep DE in discreet areas ofd the home where fleas may occur, since the eggs can live many months even if the adult population is eradicated.

      It is not likely the DE will aggravate the cat's wounds, but you should try to keep the cat away from the DE so the wounds can heal unimpeded.

  • From Diane at 7/12/12 3:04 PM
    • Hi, I have seen some DE that is cut with something, is your DE 100% or is it cut with another product? Thank you.
    • The insect dust is 100% food-grade diatomaceous earth - it is not cut with any other products.
    • Do you find this question helpful?  Yes  No
  • From Cathy at 7/20/12 1:27 PM
    • Part 1-Will this product hurt my carpets?
      Part 2- It is hard to keep completly away from vents in most rooms as they do blow across the area. I have tried to work it in and under rugs as best as I can but will it still be blown in to the air?
    • Diatomaceous Earth is a dust, and should not harm your carpets any more than other dust that could be brought into your house from outside. As for the vents, you mainly want to avoid placing the dust directly around the vents so that a large amount of the dust is blown into the air. You should still be able to operate air conditioning or run fans in your house while the dust is spread out, especially if you have worked it into your rugs or placed it underneath them.
    • Do you find this question helpful?  Yes  No
  • From August at 7/20/12 7:56 PM
    • Can I put DE on myself?
    • You can put DE on yourself in terms of safety, but it would not be particularly effective in deterring insect pests. The DE takes time to be effective, since it kills the insect by scoring the carapace which dehydrates the insect. For personal protection, you would do better with Herbal Armor or similar insect repellents.

      DE is not a repellent. It is a nontoxic form of insecticide which is most effective over time. We leave DE in small piles about the house in areas where it is not visible. This keeps the insect population down and in some cases eliminates the insect population entirely.
