Insect control through the use of an insect growth regulators is achieved by volatilization of the active compound from a point source in a spatial region such as a room, to diffuse through the air in the region toward objects in the region such as a carpet or a piece of furniture. The ability of the insect growth regulator to retain its activity when applied in this manner, even after periods of time in excess of one month following volatilization, is surprising in view of pre-existing methods of application that involved application of the insect growth regulator directly to the surface or object of interest in liquid form.
