Safer® Brand Diatomaceous Earth – 4 lb – How to Use D.E. Safer® Brand Diatomaceous Earth (D.E.) provides 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 with this powder, it immediately goes to work to completely kill them within 48 hours.

Safer® Brand D.E. is non-staining and has no odor, so you can confidently apply it in your home. D.E. also works outdoors to eliminate crawling insects as they try to sneak inside your home. Just keep in mind that it will need to be reapplied after watering or rain.

Kill Crawling Insects Within 48 Hours By applying Safer® Brand Diatomaceous Earth where you have a crawling insect problem, you’ll notice that D.E. goes to work right away! After applying D.E., you’ll find that bugs die within 48 hours. If you have a large infestation, it may take a few days for all insects to come in contact with the powder and the infestation to end.
Kill crawling insects within 48 hours
A Mechanical Killer
A Mechanical Killer Diatomaceous earth is not like other insect killers on the market today. Insects cannot build up an immunity to D.E. since it works as a mechanical killer to kill insects on contact. In fact, this dust-like powder is made from crushed fossilized algae, a.k.a diatoms that come from freshwater sources. To people, it feels like a fine powder, but these tiny fossil shards are very sharp when insects with delicate exoskeletons encounter them. After application, insects cross through the powder, which tears into their exoskeletons, causes them to dehydrate, and they die within 48 hours.
Sprinkle Directly Where Insects Live Apply Safer® Brand Diatomaceous Earth 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.

A Solution for Bed Bugs
A Solution For Bed Bugs 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. 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 your windowsills and openings in your bedroom, too. Once the bedbugs come into contact with D.E., they will die within 48 hours.
A Solution for Fleas 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.
A Solution for Fleas
Solution for Outdoor Insects
A Solution For Outdoor Insects D.E. can also be used to get rid of crawling insects found on the exterior of your home. Apply it in a band around the foundation of your home or business to kill any insects that cross through it. Just remember that D.E. only works to kill nuisance insects when dry, so you’ll need to reapply after rain or watering.

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 Safer Brand®
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 Safer Brand®
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.
