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.
- LONG-LASTING INDOOR & OUTDOOR PROTECTION : Remains effective as long as the powder stays dry. Use in basements, attics, gardens, garages, and entry points to create a barrier against future infestations.
- 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.

Great ant k*ller. Only problem is it gets washed away with rain, which we have been getting a lot of lately. Finding the ants source is difficult in our case. So working on it.

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.

Ever since I bought this the ants have stayed away from my cooler and around the picnic table. Its easy to control the flow of the powder from the bottle. Just dont squeeze to hard.

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.

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!

Works as indicated. This is not the food grade , so it isn't kid or pet friendly, however it does work well for killing unwanted insects in your areas that kids or pets do not frequent.
