Diatomaceous Earth (DE) is an organic and natural pest control agent. It consists of fossilized diatoms, which are a type of algae. DE looks like a harmless powder, but its sharp edges damage the exoskeleton of the insect and dehydrate it. Although this is deadly to many insects, it is safe around pets and people. As gardeners are looking for organic and natural alternatives to their gardening chemicals, DE is a great option for controlling many garden pests.
