DIATOMACEOUS EARTH

Diatomaceous earth is made from the fossilized remains of tiny, aquatic organisms called diatoms. FOSSIL SHELL FLOUR

Diatomaceous earth causes insects to dry out and die by absorbing the oils and fats from the cuticle of the insect's exoskeleton. Its sharp edges are abrasive, speeding up the process. It remains effective as long as it is kept dry and undisturbed.
