Abstract
The present invention provides an insect control coil that disperses an initial burst or quick release of a high concentration of insect active ingredient into the environment to provide a fast acting initial dose together with a sensory cue indicative of the release of the active substance. In order to accomplish this, the insect control coil includes a spiral-shaped body composed of a burnable material and having an insect control active substance as an ingredient thereof, a coating on the spiral-shaped body which contains an auxiliary amount of an insect control active substance which provides an auxiliary burst of active substance when burnt, and at least one of either the body or the coating further including a sensory cue indicative of the release of the reactive substance from the coating. The coating may be formed on the tip end of the body, or alternately, may be formed intermittently along the length of the body of the coil.
