Ultrasonic Device: Composed of 4 built-in speakers for four sides of coverage and solid steel construction, the Bird-X Quadblaster QB-4 emits sounds to disorient, intimidate, and confuse unwanted birds, forcing them to find calmer and untreated areas. Strobe Light: For an added layer of effectiveness, consider our optional powerful flashing strobe light add-on that creates a multi-sensory attack to prevent unwanted bird intrusions, protect spaces from bird droppings, and maintain property aesthetics. Keep Birds Away: A humane device that emits sounds that are nearly silent to humans, this device effectively mitigates pigeons, seagulls, grackles, crows, blackbirds, sparrows, starlings, swallows, woodpeckers, ducks, geese, bats, rodents, and more.
