Harris Bed Bug Killer is a 4 lb bag of ready-to-use diatomaceous earth powder with a powder duster packed inside. It kills crawling insects mechanically: the powder cuts the waxy outer layer of the exoskeleton, the insect dehydrates and dies, and it cannot build resistance to that action. It is EPA registered for homes with people and pets and OMRI listed, so it suits households that want a non-chemical barrier treatment. Against liquid sprays and aerosols it is slower, killing within about 48 hours rather than on contact, and it only keeps working while it stays dry.
