PROBLEM TO BE SOLVED: To provide a method for exterminating insect pests and mite, comprising: subjecting a given amount of an aerosol with a specific prescription to spatially spraying treatment indoors to produce an atmosphere enabling creeping insect pests, indoor dusty mite and flying insect pests to be exterminated. SOLUTION: The method for exterminating insect pests and mite includes subjecting a given amount of an aerosol to spatially spraying treatment indoors. In the method, the aerosol includes: as mite exterminating ingredients, (a) one or more compounds selected from room-temperature-volatile pyrethroid compounds each with a vapor pressure of 2×10<SP>-4</SP>to 1×10<SP>-2</SP>mmHg at 30°C; (b) one or more compounds selected from hardly volatile compounds each with a vapor pressure of less than 1×10<SP>-4</SP>mmHg at 30°C; (c) a 2-3C lower alcohol-containing aerosol stock solution as a solvent; and (d) a propellant; wherein the compounding ratio (a)/(b) is (0.008:1) to (0.2:1) and the volume ratio of the aerosol stock solution to the propellant is (20-50):(50-80). Besides, for the aerosol, an aerosol valve for quantitatively spraying use is equipped. COPYRIGHT: (C)2011,JPO&INPIT
