Safer® Brand Diatomaceous Earth

Leave bugs dead in the dust. That’s exactly what you’ll see with Safer® Brand’s Ant and Crawling Insect Killer. And you don’t have to worry about applying chemicals to get the job done.

Kills crawling insects within 48 hours.

Once you apply Ant and Crawling Insect Killer where you have a crawling insect problem, you’ll see insect activity stop in minutes. Infestation issues in a couple of days. Dual action. Kills insects by ingestion and dehydration. You can use it inside your home or outside on patios and walkways. It lasts as long as it’s dry.

Details on how Diatomaceous Earth works to kill crawling insects.

Diatomaceous Earth (DE) is a dust-like product that contains the crushed fossilized algae (diatoms) from fresh water. These crushed diatoms feel like powder when we rub it in our hand. But it’s very sharp to insects with delicate exoskeletons. When you apply DE, dust is ingested by the crawling insect or the insect crosses through the powder. The DE will cut their exoskeleton. This causes the insect to dehydrate and die. Insects cannot develop a resistance to it since there are no chemicals to which they can build up immunity.

What type of Diatomaceous Earth is this?

Beware. Not all DE is the same. Our DE is made of Silicon Dioxide. This comes from a freshwater source. It is the same type that is used in food-grade diatomaceous earth. Other products made of Diatomite DE are made from unnatural sources.

Use DE to solve problems with crawling insects. Ants. Earwigs. Cockroaches. Silverfish. Crickets. Bedbugs. Centipedes and more.

Directions for Use:

  • INDOOR USE: Lightly coat a thin layer of dust in the areas where these pests are found or may hide such as cracks and crevices, behind and beneath stoves, refrigerators, sinks, cabinets, garbage cans, around pipes and drains, window frames, and in attics and basements. Hit insects directly where possible. Repeat treatment as necessary.
  • OUTDOOR USE: Lightly coat the areas where pests are found or may hide including windows, door frames, and sills, and outside of entrance ways. Repeat treatment as necessary.
  • For full instructions depending on indoor/outdoor use and specific plants and insects, please refer to the Instructions link to the left.

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

Response From Havahart®

It can take 24-48 hours for insects to die after coming in contact with this product. The product will have no effect on larvae or eggs, so multiple methods may be needed to eliminate an infestation. Please contact us directly at 855-767-4264 with any questions, we're happy to help!

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 Havahart®
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 Havahart®
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?

Unable to review product yet since only put down today By sannsal

I put down this product today on my lawn because of having chiggers. I also put it down on soil that I will plant vegetables in during the next couple of days. From what I've read from your comments below, I'm not sure now if I can plant these vegetables. I have tomatoes, swiss chard, herbs, and cucumbers. Please let me know asap if at all able. Thank you!

Response From Havahart®
Jennifer : Consumer Relations Representative

While this product can be used outdoors around cracks and crevices, it is not recommended for use in a vegetable garden as it is not a food grade product. We recommend watering the garden until there is no Diatomaceous Earth left behind.

Please feel free to contact our Consumer Relations Team at 1-855-7-ORGANIC (1-855-767-4264) with any questions or for additional assistance.
