Ultrasonic bird repeller is for outdoor use

Ultrason X is an ultrasonic bird repeller for exterior use, eliminating the need for an enclosed area for the sounds to reverberate. Silent to humans, the unit targets pest birds with ultrasonic waves that move from speaker to speaker and force birds to leave for good. It is harmless both to the birds and to the environment. Surround-sound directional speakers are separate from the control box for all-around flexibility. The system operates on 110 VAC, and comes with a control box and four speakers with 100-ft cords, AC adapter with cord and instructions. One unit covers up to 3,600 sq ft, or 900 sq ft per speaker.
