Pest control is the process of eliminating, reducing, or managing pests—organisms like insects, rodents, plants, and fungi—that cause harm to human health, agriculture, or property. It involves regulating pest populations through methods such as physical barriers, traps, chemical pesticides (insecticides, rodenticides), biological controls, and integrated pest management (IPM) strategies. The goal is to protect human welfare, prevent economic losses, and maintain a healthy environment.
