Diatomaceous Earth



When a bug comes into contact with DE, it works under the insect’s shell and punctures the body with DE’s microscopic sharp edges, absorbs all the moisture, and causes the bug to die of dehydration.

DE is made from Diatomites, which are rough, porous fossilized mineral deposits formed near dried up water. The mineral is a result of dead single-celled algae called diatoms usually found in marine sediments. Diatoms account for ¼ of all photosynthesis on Earth. The size of each diatom is about the width of a human hair (0.5 mm). While some diatoms float by themselves, many diatoms group together and form suspended chains near the surface of water or attach themselves to rocks or plants under water.

Diatoms have hard shells that resemble tiny pill-shaped glass houses made from silica. Silica is one of the hardest solids on earth and can be found in glass and concrete. Silica makes up 26% of the earth’s crust by weight.
