The squirrelinator is a live trap for squirrels. They advertise it on this site. It's also available online and most hardware stores. It's about $50.00.
The squirrelinator works great. Just don't leave it in the sun this time of year. They won't last more than an hour or two in the sun. It will wipe out your squirrel population quick though. About 50 bucks and well worth it.
