Non-chemical methods of pest control include physical controls such as traps, barriers, or manual removal to eliminate pests; biological controls such as introducing natural predators, parasites, or pathogens to control pest populations; cultural controls like modifying the environment or practices to make it less conducive to pests, such as crop rotation or proper waste disposal; and mechanical controls, which utilize equipment or devices to manage pests, like installing screens or using vacuuming techniques.
