It's all pretty much summed up in the subject line. I live in a town just south of Boston called Quincy, and on the 6th floor or an apartment building. We get pigeons on our balcony ALL THE TIME. The make that stupid cooing noise NON-STOP! Are there any non-lethal methods of keeping them away? Anyone that can help me, please do. The cooing is driving my fiance and me up the walls.
