Here's some manufacturer info on Diatomaceous earth: This is in DUST form
MotherEarth D consists of 100% diatomaceous earth which is the fossilized skeletal remains of single celled phytoplankton commonly referred to as diatoms. It works by dehydrating insects through a desiccating action. The absorptive properties of the fossilized cell-walls easily remove the cuticle's outer waxy layer. This results in the loss of an insect's ability to maintain proper fluid levels-ultimately leading to death. Unlike boric acid dusts that work best when ingested, MotherEarth D only requires contact with the insect to be effective.
