JT Eaton 203 Bedbug Powder 7oz Insecticide, Kills Bedbugs And Crawling Insects Powder, specially designed to control crawling insects ideal for the home, residential, business, and commercial areas. This powder controls food infesting and nuisance insect pests like ants, bedbugs, boxelder bugs, cockroaches, crickets, fleas, silverfish, ticks, sowbugs, millipedes, and houseflies resting on treated surfaces. This powder kills insects by abrasively removing and breaking down the oily protective membrane which covers the insects body, legs, and other moving parts. Death results from dehydration, because it absorbs up to 50 percent of the insects fluids. An insect's body body is approximately 65 percent water and when it as little as 30 percent dehydration occurs the insect will die.
