The giant Scare Eyes will scare away nuisance birds who are repelled by the bright color and unusual design. The eyes exaggerate the glaring eyes and graping mouth of a predator bird. The waving streamers, bobbing, and weaving motion stimulate a live predator bird which frightens the bird immediately. The package includes a white, yellow, and black Scare Eyes repeller. Research shows maximum effectiveness is achieved by rotating the different colors. No color should be used for more than 3 weeks or they will lose their effectiveness.
