<p>A technique for controlling pest insects by causing an air stream to impinge against a chemical holding member holding a chemical under a non-heating condition and evaporating chemical components from the chemical holding member. This applicator (1) includes a fan (8) for generating an air stream flowing from a suction port (6) to an exhaust port (7) inside a chamber (2) and a motor (5) for driving the fan (8). The applicator (1) uses the motor (5) having a running current of not greater than 100 mA at non-load or air stream regulation means for regulating the condition of the air stream so that the evaporation quantity of the chemical components per unit time is optimized depending on the application environment, or both of them. <IMAGE></p> |
