This package includes the QB4 ultrasonic bird repeller and the clip on flashing strobe bird deterrent.
A powerful combination for keeping birds out of buildings and sheds.
The QB-4 emits powerful ultrasonic harassment sounds at a high frequency which is virtually inaudible to humans, but is very annoying to birds and rodents, although it will not harm them. The output sound frequency can be set to modulate to create an environment birds can't get used to.The flashing strobe is an effective visual deterrent.
The combination of ultrasonic harassment sound and flashing light will keep birds out of your building.
3 frequency settings:
VARIED - modulates frequency up and down at a rate controlled by the warble rate knob. During each cycle, the frequency modulates between 22 kHz and 30 kHz with peak sound pressure occurring at 22kHz.
ALTERNATE - alternates between varied mode and steady mode, each mode lasting 12 seconds.
STEADY- fixes sound output at a constant 22 kHz.
Specially designed for mounting on the ceiling of large buildings
