Diatomaceous Earth or DE is soft, sedimentary rock that consists of the remains of a hard-shelled algae called diatoms. It is micronized into a fine powder for use around the home and garden.
According to the NPIC, National Pesticide Information Center, diatomaceous earth does not have to be consumed to kill an insect. It causes the insect to dry out and die by absorbing oils and fats from the cuticle of their exoskeleton. Because it has microscopically sharp edges (harmless to mammals), it abrades the exoskeleton which speeds the process along.
For pest control purposes, diatomaceous earth is generally used as a barrier repellent to hard-bodied insects. Diatomaceous earth is a good way to manage any of the following pests: Ants, Bedbugs, box elder bugs, carpet beetles, centipedes, Crickets, Cockroaches, earwigs, Fleas, Grasshoppers, millipedes and Silverfish.
