HPotter Haven't found a solution yet but I'm sure there will be new gatgets this year.
We have peach trees, I tell DH you can't feed the squirrels year round and not have problems. They show no mercy when it comes to peaches. All day long up the tree get a peach, come down the tree with the peach eat it and back up the tree for another peach.
First he gets one of those fake owls, works for a while. But squirrels love peaches and pretty soon they realize this owl is not threat. Next he gets wind chimes also works for a while. He now has the brillant idea that he will hang a radio in the tree. This seems to work for some time and I get to listen to music while gardening. He informs me I cannot leave the radio on a music station I have to change the channel to a talk radio channel. I didn't know squirrels knew the difference but I guess they do because they dance right up that tree for peaches. Now I know he's lost it. I look out the window and he has large stuffed DINO's tied to the base of the tree.
When he finally finds the right deterrent for squirrels I going to patient it.
