I was all set to say, Animal Control, until I saw so many replies suggesting they may kill it (or them).
I got rid of squirrels last yr (they were on our roof, heading for the attic and it sounded more like a herd of cattle), through a private company that has a zookeeper's lic., and they place the animals way out in the boondocks. But it cost me $110. I called it conscience money.
I'm such a loser. I mean, squirrels are a dime a dozen. So to speak.
