Kills Insects Within 48 Hours

Safer® Brand Ant and Crawling Insect Killer takes care of pest problems without harsh chemicals. The diatomaceous earth insect killing powder is made up of finely crushed algae fossils. Though it feels soft to the touch for us, each microscopic piece is like a tiny shard of glass to small insects. As a mechanical killer, it shreds insects' exoskeletons as they move across it or ingest it, killing them within 48 hours by dehydration.

How to Use It

Bottle has a convenient pour spout for reaching tight spaces. Sprinkle the Safer® Brand Ant and Crawling Insect Killer diatomaceous earth powder in areas where you suspect insect activity, or spread it as a barrier to entry points in your home. This includes areas such as:

  • Sidewalk cracks
  • Behind or around appliances
  • Under sinks
  • Around garbage cans
  • Around pipes and drains
  • Along window frames
  • Attics/Basements
  • Entrances
  • In gardens

After application, simply wait for the product to target the insects. Large infestations can sometimes take a few days for insects to make contact. Remember to reapply after rain or watering to replace the diatomaceous earth that has washed away.

This product does not appear to be effective for controlling ants.
May 30, 2023
Tried this product for the first time. Have used it for a couple of weeks now on my front interlock patio where there were at least 10 to 15 ant hills. I applied this product approx. 5 or 6 times over the two weeks and it is not effective. Today I went out to look and there were at least 15 ant hills still, not necessarily the same ones but still....I suppose I should somehow mark them so I know for sure. However, definitely not getting rid of them.

We moved into a house ...
Jan 21, 2022
We moved into a house that had a minor bug problem initially. We would occasionally see a roach or two in the house, but they really started to hang out in the garage at night and I could not take them coming into the house a lot. I read up and found out about diatomaceous earth and liked that it was not harmful to children or pets. I applied it around baseboards and in crevices and outside around areas they may enter. It did not take long before I totally stopped seeing roaches in the garage. I was totally shocked. I left the powder down inside as well to get any that might sneak in later. We are now in a different house and I have just dusted because I saw one big roach and a couple of babies. I will do the outside perimeter as soon as it is dry out. Hopefully this will take care of it just like the last time.

Frustrated by ant needed & safety issues
Apr 1, 2021
I bought two 3 bags but had only my hand to spread powdery substance over large overgrown area to kill fleas for cats and humans. I will need another six bags to even begin to cover area. I’m on social security and can’t afford that. Secondly I was told by local animal control that it was safe for humans and animals. Your operator said I had to remove my outside cats for 24 hrs. Which I can’t do. Now I’m not so sure if I should buy more even if I could find a way to afford. Also I didn’t initially know that I had to go thru another corporation to reach Safer until I checked my bill. I’m no computer person at 73 so really had me frustrated. Good phone service once I found it. Thank you for listening to me.

Flea treatment
Apr 14, 2020
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
Mar 4, 2020
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
Jan 14, 2020
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

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!

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.

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.


This product lists diatomaceous earth at 85% and 15% "other ingredients". How is this product different than Food Grade DE? What is in the 15% other ingredients?
Question by: Heather Hall on May 4, 2023, 10:21 AM
Our DE is naturally sourced, and therefore there will be other ingredients found alongside the silicon dioxide (minerals and oxides). These ingredients are naturally present in the DE and are not additives.

Because this product is intended for use as an insecticide, it is not considered food grade.
