PROBLEM TO BE SOLVED: To provide an aerosol agent inhibiting nest building activities by bees by a jet treatment in advance at place where nest building by bees is assumed, and further exterminating bees in a nest by direct injection to the nest which has been already built and capable of inhibiting bees which escaped from extermination from coming back to the nest, and to provide a control method of nest building by bees using the same.SOLUTION: An aerosol agent for controlling nest building by bees contains an aerosol raw liquid containing (a) a slightly volatile pyrethroid-based insecticidal component, (b) a higher fatty acid ester compound having a boiling point of 180°C or higher as a component for controlling nest building by bees, and (c) a saturated aliphatic hydrocarbon solvent having 12 to 18 carbon atoms; and (d) a propellant, and a compounding ratio of (a) the slightly volatile pyrethroid-based insecticidal component and (b) the higher fatty acid ester compound having a boiling point of 180°C or higher, (a)/(b) is 1/5 to 1/50 mass ratio. There is also provided a control method of nest building by bees using the same.
