METHOD FOR OBSTRUCTING INVASION OF INSECT PEST

摘要

PROBLEM TO BE SOLVED: To provide a method for obstructing the invasion of insect pests by which the invasion of insect pests from the outside to the inside of a house is effectively obstructed by the spray of an aerosol containing a normal-temperature volatile pyrethroid-based insecticidal component in a terrace, a veranda or the like. SOLUTION: The method for obstructing the invasion of insect pests includes spraying the aerosol containing the normal-temperature volatile pyrethroid-based insecticidal component, and obtained by filling a compressed gas as a propellant so that the average sprayed particle diameter may be 50-150 μm, and the treating amount by the normal-temperature volatile pyrethroid-based insecticidal component based on the target treating area may be ≥0.5 mg/m2to form a barrier space of the normal-temperature volatile pyrethroid-based insecticidal component at the upper space of the target treating area and to obstruct the invasion of the insect pest into the space over 6 hr or more.
