I haven't hunted squirrel in years. But when I was working, came home one morning could get to sleep because of the pecans hitting the roof. Went out and scared them, in a few minutes they were back. I got the gun and shot up into the tree, they left again. And came back to, I got 27 in two mornings out of the two pecan trees in my yard.
Our bow season here starts Oct 15, 20 miles north of me it opens Oct 1. Our deer season goes until the middle of Feb. I got two last year, both were within 200 yard of my house.
