PURPOSE: To effectively execute vermin extermination, sterilization, deodorization, disinfection, etc., by applying this machine to a gardening house, a general house, a store, etc. by providing a vermin exterminating part for discharging an evapotranspired insecticide and exterminating vermin, and sterilizing part for executing sterilization by allowing gas to pass through in chlorine dioxide gas.

CONSTITUTION: As a fan 5 is rotated, a heater 7 is heated. As a result, air which flows in from a suction port 3 flows in the direction as indicated with a two-point chain line (a), is warmed by the heater 7 and is supplied to an insecticide carrying body 9 packed in a bag in a container 8. Therefore, an insecticide impregnated in the insecticide carrying body 9 is evapotranspired and exhausted as insecticide gas to the outside of a device. Subsequently, this gasified insecticide fills a gardening house or a room and vermin extermination is executed. Next, a fan 12 of a sterilizing part 2 is rotated. As air flows by the fan 12, it is gasified and a space part 16 is filled with chlorine dioxide gas. In such a way, the insecticide contained in air is eliminated, and also, sterilization, deodorization, and disinfection are executed, and air is purified.
