Balcony Guard Ultrasonic Bird Repeller

Balcony Guard utilizes ultrasonic sound waves to efficiently and effectively frighten, annoy, and intimidate birds and other wildlife within its 900 sq. ft. range. Birds don't like this at all and will stay away. Ultrasonic means that it is virtually silent to humans, so you can effectively get rid of birds while maintaining a comfortable, enjoyable, bird-free environment for yourself.
