Fumigation and fogging are pest control methods with distinct applications. Fumigation involves sealing a structure and introducing gaseous pesticides to eliminate pests throughout the area, including those hidden in inaccessible spaces. It is particularly effective against termites, bed bugs, and other pests that reside deep within structures. Fogging disperses a fine mist of insecticide into the air, targeting flying insects like mosquitoes and flies. The choice between fumigation and fogging depends on the specific pest problem and the extent of the infestation.
