Harris Diatomaceous Earth Crawling Insect Killer, 4lb with Powder Duster Included Inside The Bag

It's not instantaneous but it does kill grasshoppers. The nasty buggers were eating my Amaryllis down to the dirt! I've been chasing them around the yard but this is much better!

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.

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.

I’m telling you these corporations convince us that we need to use chemicals that are dangerous for our children and our pets and even us… For everything even our medication. But we don’t have to - for example this stuff will kill your cockroaches, but totally safe for pets, humans and babies. But don’t feed it to anyone this particular bag is not the edible kind.) Works better than the dangerous chemicals… Imagine that. Yet, they keep spraying the dangerous stuff.

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.

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?

Works well, I will say I have trouble sometimes getting out of the bottle with the design either nothing comes out or a big amount all at once. But the product works as intended and will buy again.

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.
