Bird Diverters are teardrop shaped hanging visual bird deterrents that feature a predator eye on a reflective surface. A swivel attachment allows the Diverters to rotate 360° for added effectiveness. The shiny, reflective surfaces act as a harmless optical illusion to birds. When they see the mock predator eye and shiny reflective surface of the Diverter, they scatter. Bird Diverters are ideal for fruit trees, patios, and anywhere else you want to keep birds away. Each Diverter measures 5" long and 3-1/2" wide. 5 diverters/package.
