A technique for controlling pest insects by causing an air stream to impingenagainst a chemical holding member holding a chemical under a non-heating conditionnand evaporating chemical components from the chemical holding member. Thisnapplicator (1) includes a fan (8) for generating an air stream flowing from a suctionnport (6) to an exhaust port (7) inside a chamber (2) and a motor (5) for driving the fann(8). The applicator (1) uses the motor (5) having a running current of not greater thann100 mA at non-load or air stream regulation means for regulating the condition of thenair stream so that the evaporation quantity of the chemical components per unit timenis optimized depending on the application environment, or both of them. |
