Chase away overhead bird infestations with sound waves that are inaudible to the human ear. The QuadBlaster Electronic Bird Repeller is designed to act as an important aid in routing nuisance birds from barns, storage sheds, warehouses, garages and other indoor areas where roosting is a problem. Four internal speakers generate overlapping UHF sound waves that create an irritating environment that makes it difficult for birds to stay, yet is silent to humans. NOTE: Risk of hearing damage with extended exposure at a distance of less than 10'. Do not place near a location where employees spend an entire work shift.

• Adjustable: To maximize effectiveness, the speakers can be adjusted to run at a constant 20 kHz, "warble" between 20-30 kHz or alternate between a constant and warble output in 12 sec. bursts
• Easy Installation: The unit can be plugged into any 110V AC outlet and conveniently mounted in any direction or on any plane with screws, nails, wires or adhesives (not included)
• Great Coverage: Covers up to 6,500 sq. ft.
