The High Wind Intimidator is a professional grade avian deterrent which uses motion and bright flashing to scare away woodpeckers and other birds from unwanted areas. This version of the Intimidator is made specifically for high wind areas such as lake homes and open field areas that experience regular high winds. 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. Dimensions of the Intimidator flashing pieces are 14"L x 4" Wide. Comes with a 17" mounting arm.
