How It Works

Safer® Brand Diatomaceous Earth (D.E.) provides effective pest control against a variety of crawling insects. This ready-to-use powder-like insecticide is super easy to use and can be applied to places where insects spend most of their time. Once insects come in contact or ingest this dual-action powder, it immediately goes to work to completely kill them within 48 hours.

Our D.E. is non-staining and has no odor, so you can confidently apply within your home. D.E. also works outdoors to eliminate pesky crawling insects in your garden. Just keep in mind that it will need to be reapplied after watering or rain,

Kills crawling insects within 48 hours.

Once you apply Safer® Brand Diatomaceous Earth in areas where you have a crawling insect problem, you’ll notice that D.E. goes to work right away! This unique dual-action crawling insect killer uses two modes to eliminate bugs – by ingestion and touch. Now you have a two-prong approach to getting rid of nuisance crawling insects inside and outside your home.

After applying D.E., you’ll find that bugs die completely within 48 hours. If you have a large infestation issue, it may take a few days for all insects to come in contact with the powder and the infestation to be gone.

A Mechanical Killer to the Rescue

Diatomaceous earth is unlike most other insect killers on the market today. Insects cannot build up an immunity to D.E. since it works as a mechanical killer to begin killing insects on contact. There are no chemicals in D.E. like there are in other chemical elimination products that insects can build up an immunity to.

This dust-like powder is made from crushed fossilized algae, aka diatoms that come from freshwater sources. It feels like a fine powder when we rub it in our hands, but these tiny diatoms are very sharp to insects with delicate exoskeletons. When applied, insects cross through the powder or ingest it, effectively cutting their exoskeleton and causing them to dehydrate and die within 48 hours.

Sprinkle Directly Where Insects Live

Safer® Brand Diatomaceous Earth effectively kills a variety of crawling insects including bedbugs, cockroaches, earwigs, grasshoppers, ants, crickets, millipedes, centipedes, silverfish, carpet beetles, fleas, and more. For quick results, apply directly to cracks and crevices inside and outside your home, hitting these insects directly where they live and breed.

Coat a thin layer of dust underneath and behind appliances, furniture, doorways, windowsills and other hiding places throughout your kitchen and living areas. And if you see any insects while you’re applying, make sure you sprinkle D.E. directly on them for further benefit. Don’t forget to apply in nooks and crannies of attics, basements and garages as these places are known hotspots that many crawling insects love to hide in.

A Solution for Bedbugs, Fleas, and Outdoor Insects

In order to use diatomaceous earth to get rid of a bedbug infestation, it’s important that all areas of the bedroom are thoroughly dusted. It’s best to dismantle your bed and bedframe in order to reach every crevice where bedbugs hide. Dust all areas of the bed with D.E., including the edges, folds and surface area of the mattress. It’s even a good idea to dust D.E. your windowsills and openings in your bedroom too. Once the bedbugs come into contact with D.E., they will die within 48 hours.

If you’ve found that fleas have entered your home, whether they came inside with your pets or by another means, D.E. can help! Thoroughly apply diatomaceous earth to cracks and crevices, baseboards, and carpets wherever fleas are suspected. You can also use D.E. on the floor and bedding where your pet sleeps. Be sure to keep your pets out of the affected areas and off the bedding until the flea infestation is gone and D.E. is cleaned up and removed.

D.E. can also be used to get rid of crawling insects found on the exterior of your home and even in your gardens. Just remember that D.E. only works to kill nuisance insects when dry, so you’ll need to reapply after rain or watering.

Silicon Dioxide D.E. vs. Diatomite D.E.

There are many forms of diatomaceous earth out there, but not all are the same. Our D.E. is made of Amorphous Silicon Dioxide which is composed of crushed fossilized algae that comes from freshwater sources. This is the same type of D.E. that is used in food-grade diatomaceous earth and is mined from natural sources found throughout the world.

Synthetic Amorphous Silicon Dioxide, or Diatomite D.E., is another form of D.E. that’s commonly available. This kind of D.E. is manmade and doesn’t come from natural sources. It’s not a good idea to spread this type of D.E. inside your home or in areas where children, people or pets go.

Flea treatment By Davenport
If trying to get rid of fleas in the home, after applying to the carpets, can the tenants still walk on the carpets? The description is somewhat vague.

Kills bedbugs By Kara

I’m a case manager who goes to peoples homes and unfortunately brought bed bugs to my home from one of the houses I visited. This stuff is the real deal! It’s true that a little goes a long way. I dusted this Lightly around my bed, on top of my bed spring, mattress, head board, along the edges of my furniture and walls. I even dusted lightly on my carpet and entrance of my room. Slept in my living room for about 5 days, went back and vacuumed most of the dust, still leaving tiny bits of it around my bed and along the walls and furniture and no bites since! Thank God because those bites were brutal and annoying to wake up to. Thank you DE.

Not working on flea infestation By Kilo

I'm giving this product a 3 for now because I do not know how long it takes for it to kill fleas in a severely infested house. Is there a schedule I need to start making? I put this on my carpet but I still see fleas popping continuously

Livestock By Happyknitter81

I got this from a farm store and I think they gave me the wrong product. I was wanting to add this to the flooring of my chicken coop and goat house, under their bedding to help with pests. Do I need to exchange this for food grade? I don’t want to sicken my livestock.

Response From Victor®
Lauren : Consumer Relations Representative

This product is designed to be used to help control insects. It can be sprinkled around cracks and crevices and near animal bedding. We do not recommend applying directly to the animals. Our food grade DE is designed for use to prevent clumping of animal feed.

Did I do this right? By Kiri

A liberally applied the DE over the top of an ant hill and for several feet around it. The ants are just crawling over the top of it. They seem to be packing trails. Is this what is supposed to happen? It's been almost 24 hours and I havnt seen any results yet.

Response From Victor®
Lauren : Consumer Relations Representative

Hello Kiri - Thank you for reaching out. When applied, insects that crawl through the product will die within approximately 48 hours of coming in contact with the product. As they crawl around through it, it begins to break down their exoskeleton, causing them do dehydrate, and eventually perish. Please reach out to us directly at 1-855-7-ORGANIC (1-855-767-4264) with any questions.

Safe for pets By Peggy

Just applied, waiting on results for any issue. Once this has been spread in the backyard, if a dog/cat licks or rolls in it will it harm the pet?

Q.Is this product safe to be used in the house around newborns?

This product can be used around children. We recommend only applying a very thin layer along cracks and crevices, and allowing the product to settle before having chilren back in the treated area.

Q.I read that food grade d.e. can be used in pets food & litterboxes to kill bugs. Also of pets ingest it, it can kill parasites such as worms. Is this true & can i do that with non-food grade d.e.?

We can only speak to our products. Our DiatomaceousEarth is not food grade. We recommend placing it in cracks and crevices where pests are found such as beneath and behind refrigerators, cabinets, stoves, garbage cans, window frames and in attics and basements.

Q.Is this safe for cats to get into?

Pets should be kept from the area until the product has settled.

This is not meant to be consumed and should be applied in a thin layer along cracks and crevices.
