Hunt where the squirrels are, then get in the woods and set your butt down and shut up. early morning from about 7:00 AM till about 10:00 AM Afternoon from about 3:30 PM till dark. Shoot a few squirrels then pick them up and move to another area.
Where I hunt them there is no reason even on windy days to not fill your quota in the morning unless your a awful shot. or can't sit still. I use a Ruger 77-22 with a cheap 3x9 scope on it.
One year I was hunting deer in a new spot. Seen so many squirrels in the area I wanted to return to hunt them.
I took a 5 day vacation early December and shot so many squirrels and cooked them I got sick of eating them and started giving them away.
Just sitting in my deer blind.
Gnawing on bones.
