get some peanut butter and a hide, find a branch you know they use and spread peanut butter on it, set out the hide from a good shooting place and leave it for a few days and keep feeding them, then sneakin into the hide and wait.
personally never tried this but sounds like a plan, failing that get yourself a .410 or 20 bore and shoot them as they run from you, this is how i shoot my squirrels....great fun!.
