Hi. I live in middle Tennessee surrounded by trees. Hawks are my big problem…at least they were.. they are not now, thanks to a friend who told me his secret. He has ducks and chickens on a large lot. He told me to use disco balls on shepherds hooks. I did, and haven’t seen a hawk since! After all the money we spent on netting to cover a very large area..now I have two large areas using disco balls. They move in the slightest breeze, and reflect light in lots of directions. I’m sold on them!
