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.
L'invention porte sur une spirale anti-insectes à libération discontinue dispersant dans l'environnement une bouffée initiale ou libérant rapidement une forte concentration d'une substance insecticide, cette dose initiale à action rapide s'accompagnant d'un marquage sensoriel indiquant sa libération. Le dispositif anti-insectes comporte à cet effet: un corps en spirale fait d'un matériau combustible dont un ingrédient est une substance insecticide; un revêtement disposé sur le corps spiral contenant une quantité supplémentaire d'une substance insecticide dont la combustion produit une bouffée supplémentaire de substance insecticide; et un marquage sensoriel compris dans au moins le corps ou le revêtement indiquant la libération de la substance insecticide du revêtement. Ledit revêtement peut être disposé sur le sommet de l'extrémité du corps, ou en variante, par intermittence sur la longueur du corps spiral.
