Diatomaceous earth is a natural substance made from fossilized algae that makes up 26 percent of the earth's crust by weight. It's a rather abundant resource.

This material works as a natural pesticide by dehydrating insects due to its abrasive qualities and affinity for absorbing the lipids from their exoskeleton. It's not a poison or smothering agent.

Diatomaceous earth can be applied to the ground around your plants or even sprinkled on the foliage to control snails, slugs, and other crawling insects.

To be effective, it needs to be reapplied after every rain due to its dried nature.
