a chemical substance or agent that is used to kill or control insects that can cause harm to humans, crops, animals, and structures
Insecticide is a chemical substance used to kill or control insects that harm plants, crops, or structures. It comes in various forms, such as sprays, powders, or granules, and is applied to areas where insects are active. Insecticides work by affecting the insects' nervous system or other vital functions, causing them to die or stop reproducing. They are commonly used in gardens, farms, and homes to protect plants from pests like aphids, beetles, and mosquitoes. However, insecticides must be used carefully to avoid harming beneficial insects or the environment.
