Diatomaceous Earth (DE) is a naturally occurring type of silica rock that is razor sharp on the microscopic level. It is comprised of 90% silica and is the result of fossilization of hard shelled animals called diatoms that lived many years ago (>100,000).
DE is used as an insecticide as well as a source of Silica for soil mixes. The ultra fine powder (DE) absorbs the waxy outer layer of the insects exoskeleton causing them to dehydrate / water pressure issues.
