Fogging is a process of fumigation using a chemical insecticide which is called thermal insecticidal fogging. This a utilization of insecticidal liquids passed through thermal fog-generating units, where by means of heat, pressure and turbulence such liquid are transformed and discharged in the form of fog or mist blown into an area to be treated.

Fumigation operation is effective and a better option than any other methods of pest control because in fumigation process the fumigant circulates and spreads to all areas of infestation whereas spraying operation or other methods of pest control will be less effective.
