General description New design bird deterrent discs that are more effective in keeping birds away. These double-sided holographic reflective plastic discs are light deterrents that do not harm birds. They can rotate 360 degrees to reflect light in all directions, making them suitable for use around your house, garden, windows, orchards, and yards. The discs are particularly effective against various bird species, including pigeons, hawks, seagulls, sparrows, woodpeckers, crows, and geese, as their eyes are very sensitive to light.
