Diatomaceous earth is made from the fossilized shells of diatoms, an ancient kind of algae. As time passed, these microscopic shells, consisting mostly of the mineral silica, accumulated in freshwater lake beds and formed huge silica deposits. When mined and ground into powder, it becomes what we call diatomaceous earth. This chalk-like powder is microscopically very hard, coarse, and absorbent, which makes it useful for many things.
Pest Control Grade
DE is a very effective natural insecticide, and you can buy pest control grade DE for this purpose. DE is naturally free of chemicals, yet its mechanical structure makes it a bug killer. DE sticks to bugs, wicking away valuable moisture from their exoskeletons. If bugs encounter enough of it, the DE will dehydrate and kill them. This makes DE a valuable remedy for fleas, bed bugs, ants, and other insect infestations.
