发明名称 Method and apparatus for dispersing pigeons
摘要 A method is provided for dispersing pigeons from a building structure in which the pigeons roost. The method utilizes a horizontally oriented light beam. The light beam is positioned two to six inches above the surface on which the pigeons roost. The beam, when it is normal to a pigeon's eye and strikes the eye, causes the pigeon discomfort and makes it fly away from the building structure. The beam is utilized for at least three consecutive days.
