Bird-B-Gone’s new Repeller is a solar-powered unit that uses continuous motion to prevent large birds from landing. Rotating rods mounted on top of the unit sweep birds off of streetlights, balconies, AC units and more. Two adjustable “arms” cover up to 5 ft. in diameter by turning continuously at 30 RPMs. Solar panel powers a heavy-duty, brushless motor.Bird-B-Gone Inc.,, (800) 392-6915
