Diatomaceous Earth (DE) is a naturally occurring, soft, sedimentary rock composed of the fossilized remains of microscopic aquatic organisms called diatoms. These skeletons are primarily made of silica.
Once mined and ground into a fine white powder, DE is used widely as a natural insecticide, a filtration aid, and even as a dietary supplement.

Diatomaceous Earth exists in two primary forms of silica that determine its safety profile. The natural, unheated state is amorphous silica, found in certified Food Grade DE, which is relatively safe and contains less . . .
