How Does Diatomaceous Earth (DE) Work to Kill Insects?

Diatomaceous Earth is effective against any insect that has an exoskeleton. This includes fleas, mites, lice, ants, millipedes, earwigs, cockroaches, silverfish, bed bugs, crickets, centipedes, pill bugs, sow bugs, most beetles, fungus gnat larvae, and some grubs. While it doesn’t outright kill them, many snails and slugs do not like to crawl over DE (and it slows them down), so it can be used as a protective barrier or deterrent. We add a light dusting of DE under the wood shaving bedding in our chicken coop to prevent mites and lice. 

Diatomaceous earth is not effective against caterpillars such as cabbage worms. Because of their thick gooey mucus layer that helps them travel safely through gritty soil, DE does not harm earthworms either. That means you can safely use a light dusting of DE in a worm compost bin that has become infested with mites, fungus gnats, or ants. Diatomaceous earth is considered relatively safe for bees – when it is applied correctly, in moderation, and not in direct contact with them.
