Features

  • POWERFUL CRAWLING INSECT KILLER : Effectively kills a wide range of crawling insects including ants, bed bugs, cockroaches, fleas, earwigs, silverfish, and spiders. A natural solution for indoor and outdoor pest control without harsh chemicals.
  • 100% DIATOMACEOUS EARTH WITH NO ADDITIVES : Made from pure freshwater diatomaceous earth, this powder is non-toxic, pet-friendly (when used as directed), and safe for use around kids and animals. A trusted choice for eco-conscious households.
  • KILLS INSECTS MECHANICALLY, NOT CHEMICALLY : Works by dehydrating insects on contact through physical abrasion. Insects walk through the powder and the fine particles damage their exoskeleton, leading to rapid dehydration and death.

  • EPA REGISTERED - Registered with the Environmental Protection Agency (No. 3-18)
  • BUILT-IN PUFFER TIP FOR PRECISE CONTROL The included powder duster features a narrow, easy-to-use puffer tip that allows for targeted application in tight spaces and cracks. Apply just the right amount of diatomaceous earth exactly where insects hideno waste, no mess.
  • TRUSTED BRAND SINCE 1928: Harris has been providing effective pest control and insect management solutions for nearly a century, trusted by professionals and homeowners alike.

    • It actually works. NO MORE ANTS!
Size: 8 oz
With the scorching Oklahoma heat, I had ants coming inside my house in 3 different places- I first tried Terro gel from Walmart, but it gets hard after a few hours and it's useless. I ordered this and put it around the inside and outside of my doors, outside around our windows, and along the ground at the back of the house where the ant hills are- and now they're freaking GONE! No trace of the little suckers. This powder works until it gets wet which is awesome. I had to cut a larger hole in the nozzle to get it to spread like I needed, but that's no big deal. ... show more

    • Works
Size: 4 Pound (Pack of 1)
I have rental property and I love this to assist in keeping bugs out and killing few that ever get in. It works, but takes few days due to way cuts bugs. Not instant results, but great for a clean up or long term control.

    • Definitely recommend for putting in the drywall to reach into far places
Size: 8 oz
Great! I had an infestation of springtails in my basement, if you don't know what they are they look like flies and jump high as well. But they don't bite humans and animals at all they survive on bacteria in water so any area with humidity they thrive in. I have a bathroom in the basement with no exhaust fan so they were breeding in the ceiling drywall. I puffed some of this in the crack between the air vent metal and drywall and along with damp rid bags and within a week they were pretty much all wiped out. I also really like that it's safe to have around animals. We get a lot of bugs in the basement so I also did in any cracks I could see that could possibly lead from the outside. It's been around 3 weeks and I have no complaints. You get alot for the price too way cheaper than bug sprays. ... show more

    • Works, but way overpriced.
Size: 4 Pound (Pack of 1)
Big bag. Comes with blower/duster thingy. Would be a 5 if they included a scoop for the powder. Refilling the puffer/blower/duster thingy is ALWAYS a mess. You can use a kitchen measuring cup, but come on, for the price, where's the dedicated cheap plastic scoop? The stuff seems to work well with cockroaches, but not so much with fleas, ticks, and bed bugs. ... show more

    • Helped with my roach problem in my apartment!
Size: 8 oz
This actually worked with my roach problem in my apartment. There is no odor from the earth at all and although it takes a while to actually work, I saw a reduction in roaches in about 2-3 weeks of use. They actively avoid the stuff so I’d recommend using it. I reapply it every 2 weeks or so just to keep it fresh. ... show more

    • Should use better packaging.
Size: 8 oz
The product itself works as advertised, but having to cut the tip of the tube with my own knife or scissors like a caveman is just unacceptable. I didn’t move out of the third world to deal with this kind of primitive packaging. Just use a better tip and charge me an extra dollar.

Messy, but works. It’s messy because of the dust but it seems to work well. I have seen no more creepy crawlers.

    • Fast, clean, simple and works like magic. Hooray for science!
Size: 8 oz
One morning my garage was filled with 100 crickets escaping the Las Vegas heat. It was like a horror movie. After a little research, I order this product with same day shipping. Spread / sprayed all along the corners and edges of the garage. The fine powder stays where it needs to be. It even stuck a bit on the walls where the bugs were. Next morning... no crickets.
