When pigeons take up residence on a balcony, residents are plagued by dirt and foul odors, and are also threatened by pathogens such as ornithosis and chlamydia. This product uses specially processed aluminum foil to diffusely reflect sunlight, and at the same time, gradually emits an odor that pigeons dislike from the slit, making pigeons less likely to approach.
