An insecticide is a chemical designed to kill insects. The name comes from insect plus cide, meaning to kill insects. Fungicides kill fungi, herbicides kill plants, and algicides kill algae. In practice, insecticides are used to control insect pests that can damage materials, spread disease, or create nuisances, and choosing the right type helps protect water quality and non-target organisms.
