The difference between pest control and fumigation lies in their approach and scope. Pest control encompasses a variety of methods, such as traps, baits, sprays, and biological controls, to manage or eliminate pests. Fumigation is a specific type of pest control that involves sealing a structure and introducing gaseous pesticides to penetrate all areas, providing thorough eradication of pests hiding in inaccessible spaces. Fumigation is used for severe or large-scale infestations, whereas general pest control is often more localized.
