HARRIS

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

Editor's bottom line:

“This best insect killer powder is the best one we tested. In terms of quality, brand and price, we couldn't ask for more.”

Main Highlights

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 product is safe for use around kids and animals, when used as directed. 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.
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.
