We've taken 17 to the "farm" since Xmas and so far haven't had another show up. For Xmas, I got a small squirrel trap from Harbor Freight! We set it and watched the squirrel go in, eat, trip the lever, and turn around to open the door and leave. We watched this over and over. Then we decided to use our "Have a Heart" raccoon trap. Same story, only they didn't trip the lever. Sooooo we tied a string to the lever and threaded it into the house thru the door. Finally, bye, bye....squirrels. Only downside is transporting them every time......far away.
