Diatomaceous Earth kills a huge variety of pests, including:

bed bugs, cockroaches, centipedes, millipedes, crickets, moths, fleas, lice, beetles, sow bugs, pill bugs, twig borers, mites, thrips, ants, termites, armyworms, fungus gnat larvae, aphids, ticks, fruit flies, spiders, silverfish, earwigs, and more.

DE is a huge deterrent or barrier against slugs and snails, but does not directly control.
