Aerosol for controlling pests and method for controlling pests

The invention provides an aerosol for preventing and removing pests, which is a quantitative spraying type aerosol for space treatment and can improve the effect of preventing and removing creeping pests. An aerosol for controlling pests, which is obtained by filling an aerosol container provided with a quantitative injection valve with a propellant and an aerosol stock solution that contains an insecticidal component having a vapor pressure of less than 1.5 * 10-3 mmHg at 30 DEG C and a solvent, the aerosol stock solution having a specific gravity of 0.82-1.25 at 20 DEG C and a viscosity [eta] 10 at 10 DEG C of 3.2-60.0 mPa.s, and the aerosol stock solution having a specific gravity of 0.82-1.25 at 20 DEG C and a viscosity [eta] 10 at 10 DEG C of 3.2-60.0 mPa.s. The ratio [eta] 30/[eta] 10 between the viscosity [eta] 30 at 30 DEG C and the viscosity [eta] 10 at 10 DEG C is 0.40-0.92, and the injection capacity of the quantitative injection valve per injection is 0.1-3.0 mL. 本发明是提供一种防除害虫用气溶胶，是用于空间处理的定量喷射型的气溶胶
