The Intimidator is a professional grade avian deterrent which uses motion and bright flashing to scare away woodpeckers and other birds from unwanted areas. Woodpeckers can cause serious damage to homes and other buildings. This deterrent is lightweight and needs very little air current to create a dynamic visual effect that frightens birds. It mounts easily to any wood surface with a single screw. Must be mounted so as to reflect flashes onto the side of the structure. Most structures require multiple units to protect all sides.
