Bird-X Deterrent Ultrasonic Bird Control with Strobe Light, Covers 6000 sq ft (QB4+S)

he QuadBlaster QB-4 is Bird-X’s best-selling ultrasonic bird control system, composed of 4 built in speakers and solid steel construction. The device emits sounds specially designed to disorient, intimidate, and confuse unwanted birds out of the treated area(s). When the pest birds are exposed to these irritating soundwaves, they are forced to find calmer and untreated areas to linger. Optional powerful flashing strobe light add-on creates a multi-sensory attack!
