PROBLEM TO BE SOLVED: To provide a method of controlling pests, which can effectively control pests in open space (particularly, in outdoor space) and reduce adherence of chemicals around the atomizing device, and an ultrasonic atomizing device which is used for it.SOLUTION: Micropores which penetrate a vibration plate 12 in the thickness direction are formed, in which the vibration plate 12 atomizes a chemical that contains a pest control ingredient by the vibration of a piezoelectric vibrator 11 that generates ultrasonic vibration by energization. In addition, the atomization time and the atomization interval time are controlled by turning on or off the energization to the piezoelectric vibrator 11 so that the value of [50% particle diameter of atomized particles in cumulative volume distribution]×[atomization time/atomization interval time] is set to be 0.2-2.5 μm. |
