Harris 8 oz Diatomaceous Earth Crawling Insect Killer — 100% Natural Dust for Ants, Roaches, Bed Bugs, Fleas — Indoor & Outdoor Use

OK I have been using this brand for many years due to its versatility and the fact its safe to use around my pets and children, it works wonders for everything from killing cockroaches, to ending bed bugs, to creating a line of ant resistance around the house. I got this one and didn't even notice it came with an application device. What a world of difference it makes. It allowed for consistent lines around the house edge while using far less than I did previous years. Its a revolution for the product

Used this in my efforts to clear out a bed bug infestation. Used it on my wall corners to leave less areas for the critters to hide, placed it around my clothes rack to also stop them from getting onto my clothes, and if they did they didn't live for long. I also placed it next to my bedframes feet so after my bed cleanings they couldn't survive reinfestations. (Used a Seekone heat gun to kill the bugs and their eggs, would recommend for killing bugs alongside this product) Application was easy, though the nozzle it came with was pretty bad. Mine would puff out powder from its sides when used even if it was tightly secured. Would recommend for dealing with bed bug pests. Was able to deal with my bad infestation in a months time. Though everyone's situation is different I think it would still be helpful in many other life's.

Bought this in 2022. Sprinkled it in “all” the corners. No live bugs and I live in FL. This stuff stays active, just as long as it stays dry. One bottle really lasts. Pet friendly. One bottle really lasts because you don’t have to reapply in the corners as long as powder exists. Now 2026. Only apply where I have vacuumed up the powder. Recommend this product and I don’t do that very often. Puffed it down a fire ant mound. Will see how that goes?

It seems as if it working very well so far. The only thing I don't like is the puffer application thing. I puffs it all over and not consistently.

This actually dries the bugs out and kills them it is a natural safe pet friendly product that is effective and works very well. It does not end the problem over night but it sure does put a halt to it.

I know this stuff works. The packaging is weak. It came with a hole in the bag and made such a mess. It's disappointing to have so much wasted product but not worth docking any more stars because this is the best bug killer I've used.

I was at my wit’s end battling an invasion of ants and the occasional cockroach when I decided to try something different. That’s when I came across this product and let me tell you, it’s been a game-changer. The product comes in a simple yet effective 8oz puffer bottle that makes application incredibly easy, especially in hard-to-reach corners, baseboards, behind appliances, and inside cracks where pests love to hide. The nozzle lets you control the flow without creating a mess, which I really appreciated. Upon unboxing, I noticed how lightweight the bottle is and how fine the powder feels—almost like flour. There's no strong odor or fumes, which makes it perfect for indoor use around pets and kids, as long as you follow the instructions. It's oddly satisfying to know that such a gentle-looking product can be so deadly to bugs. The build quality of the bottle is solid and the applicator works better than I expected. I’ve used similar powders in the past that clumped or clogged during use, but this one dispenses smoothly and consistently. It’s easy to store and seals well to prevent moisture from affecting the powder. Performance-wise, the results weren’t immediate, but after about 24 to 48 hours, I started seeing fewer ants around the kitchen and no more unwelcome roach appearances at night. I applied a light dusting along entry points and under appliances, and after a few days, it was clear that the colony had gotten the message. I also used it along the base of the bed frame and behind furniture as a precaution for bed bugs, and so far, no issues. Pros: Easy-to-use puffer bottle allows for precise application Completely natural and chemical-free, safe to use around pets and kids Odorless and non-staining, perfect for indoor use Effectively kills ants, roaches, fleas, and more with lasting results

Great to have this in the container for smaller/hard to get to spots.

Just get your beds outside to the sun it doesn't work alone you need an actual bug repellent to be acompany it

Awful packaging. Sprinkler is DEEP INSIDE and it's IMPOSSIBLE to get it outside without pouring everything out. Otherwise risk spill and ton of dust around you. And zip-lock doesn't work at all.
