Holographic bird tape flashes blinding light and makes noise when it flaps in the wind. Irri-Tape® is a multi-sensory attack scares birds away from the treated area. Sunlight reflects off the material, disorienting and irritating pest birds, and a sharp metallic clacking sound is made when the tape flaps in the wind. Irri-Tape® is easy to install, and a very simple and effective solution. Comes with 8 supports.
