Diatomaceous Earth (DE)

Diatomaceous Earth is a misnomer. It is not actually soil or dirt, but the leftover exoskeletons of microscopic algae (named diatoms). The microscopic skeletons have jagged edges which poke holes in insect exoskeletons, causing them to bleed out and die slowly. It is considered harmless to most vertebrates, such as reptiles, birds, and mammals. It is frequently used as an organic means of pest control.,
