Woodpecker Ultrasonic Repeller for Effective Bird Control

Seems to work. I have birds living in a dead pine tree in the empty lot next to me and they kept pecking at my house. I leave it on the motion sensor setting for birds and it functions properly. For good measure, I added rubber snakes, an owl decoy and windchimes and have not had a bird problem since setting it up several days ago. Hoping it lasts long, I wish the ac adaptor plug wasn't so bulky for outdoor extension cords though.
