Details

Food-Grade Diatomaceous earth comes in the form of a chalky powder, and is the natural fossilized remains of diatoms, a type of hard-shelled algae. These 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 like a light dust, it easily clings to the bodies of insects as they walk and crawl over it. The tiny diatom particles then cut the waxy coating of insects and they eventually dry out and die of dehydration within 48 hours. It 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. Non-food-grade diatomaceous earth is dangerous and should be avoided.

What insects does it control?

Insect Dust kills the following insects:

  • Ants
  • Ticks
  • Fleas
  • Aphids
  • Silverfish
  • Cockroaches
  • Bed bugs
  • Spiders
  • Carpet beetles
  • Tomato hornworm
  • House flies
  • Fruit flies
  • Red spider mites
  • Earwigs
  • Slugs and Snails

Please keep in mind that it may kill beneficial insects as well.

For indoor use:

For indoor use lightly coat a thin layer in areas where insects are found or may hide. Can be used in cupboards, behind and beneath refrigerators, cabinets, stoves, garbage cans, and in or around sewer and drain pipes.

You can leave the dust where you place it until you no longer see any signs of insects in that area, at which point you can clean it up. For carpets, lightly sprinkle the insect dust over the carpet, and leave for two to three days before vacuuming. Reapply the insect dust only if you continue to see signs of insect pests.

Thoroughly apply to areas of infestation. For example:

Bedbugs:

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.

Silverfish:

Lightly dust under the sink, inside drawers, or along the baseboards, and wherever else silverfish are found.

Fleas:

Thoroughly dust carpets and pet's bedding and sleeping areas, as well as cracks and baseboards. It also can be rubbed into your pet's fur.

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 other insects are found. Areas such as patios, windows, door frames, foundations, along ant trails and outdoor pipes and drains. Reapply the insect dust after any medium to heavy rains.

Flies:

Thoroughly dust areas where flies frequent (walls, straw bedding, livestock pens). It also 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 poop. Flies lay eggs on the poop 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 and saturate the mound. The ants will track the DE back to their nests where the colony will be exposed to its abrasive action.

Slugs, earwigs, and other garden pests:

Sprinkle DE over plants and around edges of garden beds. For best results, reapply after rain. DE which is washed into the soil will continue to benefit your garden, since it acts like vermiculite in retaining water for future slow release into the soil.

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 n the corner of the coop (or in a dry area of their run) and the chickens will continually apply themselves with DE. This will reduce or eliminate lice problems within a few days.

Safety

This product is Food Grade, and safe for your pets and your family. Insect Dust is registered as an Insecticide with the government, so it is required to have a generic health warning on the bag, despite its safety.

The 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 B. Hill at McGill University in Canada describes Diatomaceous Earth as non-toxic and feeling like talc when you touch it. He mentions that inhaling common road dust is probably more harmful than inhaling Diatomaceous Earth.

Diatomaceous Earth (DE) used in pool (or any water) filtration contains DE that has been chemically treated and heated making the silica crystalline which is a dangerous respiratory hazard and lethal if ingested. The fresh water naturally occurring DE deposits that are designated FOOD Grade by the FDA have less than 3% crystalline silica. These deposits are primarily Amorphous Silica which is harmless when ingested and is commonly used in feed and food industries.

Sustainability

Provides a non-toxic, safe way to control insect pests.

  • From Ellie at 5/30/12 11:20 AM
    • how do i go about killing spiders with de. my house is over run by common house spiders.
      .
    • Diatomaceous Earth is effective on common house spiders. The best way to use diatomaceous earth is to spread it in problem areas where the spiders are commonly seen, as well as near any areas from which they may be entering. This may include doorsills or window frames. You can also apply the diatomaceous earth to your carpets, but you will have to reapply it after vacuuming.
    • Do you find this question helpful?  Yes  No
  • From elizabeth at 5/1/12 10:55 PM
    • does it work for bed bugs???????????????????
    • Yes. Diatomaceous earth will kill bedbugs. You need to be strategic in placing the DE where the bed bugs will cross it. We place it on the ledge of the metal frame beneath the bed, and along the edge of the wall behind the bed. Bed bugs may scale walls in order to descend upon beds and other places to find food.

  • From Sandi at 4/6/12 8:17 AM
    • I am looking for something that would be safe to combat roaches ON the kitchen counter. Could DE be used for this if we did not place food directly on the counter after application? Is it safe to put inside the cupboards with dishes, etc? Any other suggestions other than those already cited in the web site?
    • Yes, it is safe to apply DE in the places you have described. One other spot to apply DE is on top of the cupboards, if there is a space. Remember, DE does not kill instantly on contact, it takes at least a few days to start being effective, and if yo have a persistent roach problem then you may want to leave DE in discreet areas permanently. (In places like the tops of cupboards, one application of DE will last indefinately since this space is rarely vacuumed.)

  • From Lynne at 10/24/11 1:16 PM
    • Hi, If the cat licks his fur after I rub it into his fur, is this safe for him? How often should I reapply this after the first application? Is it safe to rub into areas where he sleeps? Will it cause any harm for him to breath this product? I notice we should wear a mask when applying, as I have a breathing problem, but what about the cat breathing this? Our cat came to us with a wheeze from the shelter, but since he's been with us it's gone away, but I still worry about dust affecting his breathing. Thank you~L.
    • Your cat should have no problem with exposure to diatomaceous earth. However, with any new product brought into your home, we suggest that you try it in a small amount first to see if your cat has any reaction. We have not received any reports of this over the years we have been selling DE.
      In our experience, the effectiveness of DE is realized mostly when it is applied to an area, such as your cat's bed or areas in the home the cat may frequent. Application directly to the fur is done by pet owners, but we believe the benefit is secondary when compared to controlling fleas in the nearby environment.
      Results of using DE are not immediate. It takes a few days or longer before you can expect a reduction in the insect population in your home. The effects continues over time. We reapply DE in certain areas of our home every 4 - 6 months.

  • From Lauren at 8/31/11 11:45 PM
    • Is DE safe to apply around children since it is "food grade"? My child may have asthma too.
    • Yes. Diatomaceous Earth is safe to apply where children are active. You should apply DE in areas where the vacuum will not suck it up during regular cleaning, but otherwise there are no restrictions to its use. DE is safe for children and pets, and will not trigger your child's asthma.
      We have used DE in our home for several years and it has been very effective at controlling insects. My son has asthma and we have not noticed any adverse effects from using DE.

  • 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.

  • From Michelle at 7/25/11 5:40 AM
    • 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.
    • Do you find this question helpful?  Yes  No
  • 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.
    • Do you find this question helpful?  Yes  No
  • 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.
    • Do you find this question helpful?  Yes  No

Worked well for me.

By Mike on 7/21/10

My cats are outdoor cats, and they bring in fleas from time to time. If I see any evidence of fleas, I'll take a teaspoon of the DE and sprinkle it over their back, then rub it through their fur. I'll also sprinkle some around where they sleep, to kill any lingering fleas. I don't like Frontline or any chemical flea killers as they can be hard on my cats.

Not satisfied

By Pamela on 9/2/10

All my reviews  (1)

I admit this product is easy , but my animals keep biting and scratching themselves. It Is only effective on them for about 15 minutes. i sprinkle some on the area that is itching and rub it into their fur but it doesn't seem do anything. Also, after vacuuming, there are fleas still jumping. I used on carpets, upholstery, cracks on baseboards, tile floor, bedding and linoleum. The flea catcher, with the adhsive seems to work better than the dust.

Safe, easy to use, and highly effective!

By Sandra on 10/5/10

All my reviews  (1)

I have used this product to treat fleas on my cats by rubbing the dust into their fur, and I've also used it to help treat parasites by mixing it in with their food. It's really easy to apply, and safe to use with bare hands. The only caution on the bag seems to be with inhaling the dust, but when I spoke with the manufacturer they said that it's no more dangerous than road dust, and that the caution is more for people with allergies.

I'll be buying more!

the best, period!

By angel b on 11/15/10

We have a cabin that has all sorts of insects, and we come back after being away there is insect debris all over but especially in a couple spots near my chair and near the phone. ( I think this is the pillbug capital of the world!) Since we started using DE a couple years ago, there is virtually no insect matter anywhere. This is a breakthrough for us cause we've been dealing with insects in the cabin forever. The bag lasted a really long time. We use it in both our homes, and I'm now happy to buy more.
Oh, one bit of advice. Put the DE in little teaspoon size piles in spots where bugs go but where the vacuum won't get it.

very pleased

By Annette T. on 11/30/10

After several months of applying this insect dust in my home, I can say the insect population is definately reduced, and in fact I hardly see any bugs anymore. The non-toxic nature of this product is what appeals to me. I'm glad I discovered this and have been telling friends about it.

works

By Dan on 12/16/10

I first tried this stuff when finding out that we had bed bugs in the house, and been using it since. It works great. A little slower in getting rid of things, but it works. I have seen dead roaches and spiders, too, from them walking through it, and not a roach in a few months now. I suggest it to anyone with a roach problem or bed bugs, too.

effective, not toxic, but can be blown around

By del on 1/19/11

I'm buying a bag for each of my rental properties based on the successful use in my home and one rental. The product is definately effective and I can assure my renters there are no toxicity issues and won't affect people with allergies. My only criticism is that it needs to be placed where a breeze will not blow it away. You can't just put diatom earth anywhere. I recommend putting it on top of the cupboards and on the inside ledge under beds (for bedbugs).

The silverfish love to crawl over this and then reproduce!

By william on 8/3/11

Does absolutely nothing! The bugs walk all over the powder, then reproduce so it does nothing. I NEVER saw a dead silverfish after.

(Editor's Note: Diatomaceous earth does not kill instantly on contact. Once the insect comes into contact with DE, its exoskeleton becomes scored, which leads to dehydration and death. It takes a few days to begin to see results of using DE.)

Fantastic for Cats!

By Heather on 1/4/12

I was a bit skeptical at first, and had to call Eartheasy for confirmation that I could use this on my cats, but I'm so glad I bought it now!

After rubbing the dust into my cats fur, the fleas started dropping off after a couple days. This dries them up and kills them real quick, and it's totally safe to use. I'm a very happy customer, and will be buying more!

Very good explanation but.....

By Cathy on 3/30/12

I would not down play the risk of breathing the dust nor compare it to "road dust". Although I have used this product for many years here on the farm to dust stalls, farm animals, dogs and cats, etc, one must take care to NOT breathe this DE dust. I have always purchased from livestock supply stores in larger quantities. Those packages note that you should wear a mask when using this product as well!!
DE DOES work! Otherwise, I wouldnt be using it for so many years, wasting my $ or time!! Gets rid of flies, knats, fleas, ticks and many other pesty insects! Just dont get in your animal's lungs or yours!! And, remember, if it rains, it's gone! So, you will need to re-apply (common sense here)

Doesn't seem to be working

By Chaplin on 11/4/12

I have a bad flea infestation. I have been fighting fleas for almost 7 months. I have used everything from foggers to frontline. A friend recommended DE and I have covered the house and the animals with it. It has been over six weeks and there is no change, we are still infested. I vacuum and re-apply every 2 days . It looks like it snowed in my house but we are still full of fleas. I dumped some on a spider in the corner...I am waiting to see if he dies.

A Must-have for Bedbugs

By Doug on 6/13/13

Lived in an apartment that had a bedbug outbreak, use DE along with double-sided tape and mattress covers and it really took care of the problem. Haven't tried it with fleas (I find that boric acid powders work well if you have carpets). Make sure you get a good hand duster to spread it, one of the bulb- or bellows-type dusters. With the right duster, you can "spray" a spider and watch it die.

liked product

By bb on 11/14/13

I had never heard of this product until a friend recommended it. Even then, I dismissed it. But then one of my indoor cats got out and when the fleas started appearing and rapidly became a big annoying problem, I remembered the name and started looking online for the product. I purchased it, applied it and waited. The wait was successful! The fleas started disappearing and then, eventually, they were just gone! I will definitely keep this product handy. And will reuse over other pesticides that are harmful to my pets. And that's another plus: it's nontoxic to my cats. I love it! I've also recommended this product to others.

I drink it in orange juice!

By Deedra on 1/19/14

I have been eating about a tbsp a day since October 2012. I'm almost 53 and feel like I'm in my 30's. The excess silica supposedly turns to calcium (which I really need). My joints feel better, I no longer suffer from IBS. There is no scientific evidence but it really is the "bug killer you can eat!" People I work with take it in the morning (they say it gives them an energy boost. I take mine at night and don't really notice anything.
