Zusammenfassung:An insect coil (10) having an extended, burnable body (12). The body has multiple treated zones (14) bearing a volatilizable insect control active ingredient at insect controlling levels separated by spacing zones (16) bearing a level of insect control active ingredient lesser than that of the treated zones. When burned, the insect coil releases bursts spaced in time of the active ingredient in insect controlling quantities. Preferably the spacing zones are active ingredient free, and the first treated zone has an active ingredient level higher than the remaining treated zones. A method of controlling insects by the use of the insect coil is also disclosed.
