Formulated with pure Diatomaceous Earth.
Diatomaceous earth is made up of tiny, sharp edged diatoms which are special fossilized marine plants. Insects are physically very different from warm blooded animals. Instead of skin, they are protected by a hard but porous exo-skeleton covered with an oily, waxy substance which seals in body fluids. When the waxy outer surface is scratched or punctured by the tiny diatoms, the insect simply dries up and is killed mechanically, not chemically. Because the action of Diatomaceous Earth is physical, not chemical, it is impossible for insects to build up immunity against it. OMRI listed. 200g Dust
