What is Diatomaceous Earth?

Diatomaceous earth is a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off-white powder.  The powder can have an abrasive feel, similar to pumice powder.

It looks like powder but is actually a mineral dust.

How Does Diatomaceous Earth Kill Fleas?

​Diatomaceous earth is made up ​of diatoms which are the fossilized remains of a type of algae. It is the diatoms that scratch away at the waxy layer of the exoskeleton of the flea.

Moisture from the body of the flea evaporates and the flea dehydrates and dies.
