The Bird Gard strobe light is a high quality strobe light which is used usually in ceilings or other dark areas, where birds such as pigeons, sparrows, swallows or starlings nest or roost.
Most people have experienced the sickening nausea that follows after watching a strobe light for too long. This applies also to birds and the strobe light will not let them settle or sleep. It is a constant, sickening, confusing irritant which will eventually drive the birds away to somewhere more "friendly".
Just plug it in (to a standard power outlet) and let the strobe work for you. Sometimes the strobe is used in conjunction with Pigeon Repeller, Swallow Repeller and Sparrow Repeller.
