PROBLEM TO BE SOLVED: To provide a blower capable of suppressing the transpiration of an insecticide in its nonuse and of increasing its transpiration relative to airflow level. SOLUTION: This blower has the following scheme: the opening of either the suction port or blow port of the blower body 1 internally mounted with a fan 2 between the suction port 5 and the blow port 6 is made to communicate with an airflow path bent relative to the airflow direction at the opening, and an element 16 holding the transpirable insecticide is placed in the airflow path so as to allow air to flow in the longitudinal direction of the element 16.
