Every year I have this beautiful pear tree that is loaded with pears and the squirrels usually take every single one of them. I am so tired of fighting these squirrels. Do you have any idea how I can keep the squirrels out of this tree? I thought about bird netting but DH says the squirrels will just chew right through it. I've tried shooting them and have killed many of them, but I can't just sit out there and guard that tree all day long.
