Diatomaceous earth (DE) is a natural, powdery substance made from fossilized aquatic organisms (diatoms) used primarily as a non-toxic pesticide. It kills insects by damaging their exoskeletons and dehydrating them, making it effective for home and garden pests like ants and beetles.
- What it Is: A soft, white powder composed of fossilized remains of tiny, aquatic organisms known as diatoms, which are rich in silica.
- How it Works: DE acts as a desiccant. It scratches the waxy, outer exoskeletons of insects, causing them to dry out and die within hours or days.
- Pest Control: Effectively controls cockroaches, bed bugs, ants, fleas, and aphids by dehydrating them.
- Garden Use: Used on plants to deter beetles, aphids, and other pests, particularly on the base of plants.
