PROBLEM TO BE SOLVED: To provide a method for controlling termites, without causing ultraviolet light deterioration and safe for a human body, since in the method for using a device for radiating ultraviolet light, the ultraviolet light is radiated on house members such as woods under a floor, ultraviolet light deterioration such as strength reduction, or discoloration, is caused on the surface layer of the members.SOLUTION: This method for controlling the termites is provided by radiating visible light of 400 to 550 nm to the termites, and also the method for controlling the termites is provided by radiating visible light of 400 to 450 nm.COPYRIGHT: (C)2011,JPO&INPIT【課題】紫外線照射装置を用いる方法では、床下の木材など住宅部材にも紫外線が照射されるため、部材の表層には強度低下や変色などの紫外線劣化を引き起こしてしまう。この紫外線劣化を引き起こすことなく、人体にも安全なシロアリの防除方法を提供する。【解決手段】400~550nmの可視光線をシロアリに照射することを特徴とするシロアリの防除方法。【選択図】図1
