Abstract
A mixture of an active ingredient such as insecticide, fungicide, repellent or the like and a blowing agent is heated with a hot air current produced by a suitable heat source and a fan to thermally decompose the blowing agent and cause the hot air current and the gas resulting from the thermal decomposition to vaporize and diffuse the active ingredient. The mixture is accommodated within a passage formed in a container and the passage is provided therein with a fan for forcing the hot air current therethrough. A fumigating method and an apparatus of this invention ensure very efficient, quick and uniform diffusion of the vapor of the active ingredients and are usable for controlling vermin and other purposes with high safety and great convenience.
