I'll give ya the 1st serious answer. Check with your local animal control and see if they will loan you a trap. Bait it with some apples, grapes and nuts, then relocate them to a wooded area. My wife has been doing this for the last week and we're down to one squirrel left from what was more than ten. Good luck. BTW we have seen a squirrel swim across the lake in our backyard, probably close to 50 yards.
