We had some mice in our house so I bought a couple of those ultrasonic rodent control devices. To test one out, I put it on the ground near the base of our bird feeder, and it didn't even phase the squirrels.
I bought little cheapie ones, that probably have a range of about 5 feet, so my use isn't a good gage of effectiveness, but I was surprised that it didn't phase the squirrels, but they were more than 5 feet away.
I wish I had that near my bird feeder!

Squirrel Rave!
Did it work, though?
I used one and it did work. I recall after a while it made them so uncomfortable that I heard a mouse stampede.
The sound grates on them and they look for a way to leave.
