How It Works

Safer® Brand Diatomaceous Earth (D.E.) is composed of 100% D.E. to provide 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 100% 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.

Rated 5 out of 5 by from SAFER Brand is excellent! We've had a bad problem with bed bugs starting back in June 2016. We're not sure how it started and were totally unfamiliar with how bad it could get. My sons had bites up and down their ankles! We hired a local pest control company and they charged us a lot of money to come in to heat treat our entire condo (which was a huge hassle too, I might add). It worked......for about a month or two. Then we found bed bugs again! I was sick about it. Spending so much money and STILL to have bed bug infestation!? I was complaining about it and my neighbor told me he had had this problem too and used SAFER Brand Diatomaceous Earth. I bought some online that very day after hearing his success story. Well, now we have another success story, I am thrilled to report. Our problems with bed bugs finally seem to be over and we have SAFER to thank....and, at a fraction of the cost of a pest control company. The SAFER product is easy to use and non-toxic too. Thanks SO much, SAFER!

Rated 5 out of 5 by from No more bedbugs I moved into a new apartment and discovered very quickly that I was not alone. The bed bugs did not move out with the prior tenant! I tried sprays, rubbing alcohol, and everything I could find after researching the internet. I was about to admit defeat and call an exterminator when I finally came across some information about diatomaceous earth. I treated my furniture, carpet, bed and bedding and after several days the bugs were gone. I've now been bug free for over a month. I'm so happy I found this product and I would highly recommend it. It works on household pests as well such as spiders and roaches.

Rated 5 out of 5 by from This stuff is AWESOME!!!! I live on Long Island and have recently experienced a tremendous outbreak of Carpenter Ants. A few months ago I demolished my old deck. It was almost entirely ground contact. Carpenter ants had attacked it and compromised the structure. In May we replaced the deck with a new paver patio. Immediately it became obvious that we disturbed the ants territory. They were crawling everywhere. I tried various brands of baits and traps. Nothing worked. Liquid baits got flipped over and left stains on our new patio. They were both ineffective and destructive. The next I discovered this product. Two days after I began "dusting" the ants and the areas that they travel, I noticed a huge difference in the amount of ants present. Before using this product I would literally see hundreds of ants within 5-10 minutes, walking across the patio. Now I have to search to find two, or three. I won't use anything else and risk staining the pavers, or waiting for an ineffective product to work.

Rated 5 out of 5 by from Really works! After battling bed bugs for about a year with 2 heat treatments we were ready to try something new and we used this monthly for 2 months and have been bed bug free for a year now. This is so much cheaper than hiring exterminators and it worked. My husband put it all over the carpet and vacuumed and there was a fine layer on everything so I think that's why it worked.

This product is very effective against fleas. Treat surrounding cracks and crevices, baseboards, carpeting, and wherever fleas are suspected. Once little to no activity is seen, the DE can be vacuumed with a filter-less/bag-less vacuum.

How long do I leave it on carpet and dog bed if treating for fleas? Can dog walk on carpet if powder hasn't been vacuumed yet?

Asked by: Kathi
DE will kill insects within 48 hours of ingestion, but the time it should be left out depends on the size of the infestation. This can be used with confidence around your pets, however we do not recommend applying it to them directly.
