TSC has a smaller box trap that I have used to catch rats. Being squirrels are just tree rats that is what I would use. This way you can contain them in the trap to kill them with your bb gun . BTW a pellet gun upgrade might be a good idea.What kind of tap would you use for squirrels? I have been chasing them around with a bb gun, but they keep coming back(of course they do free food!) neighbors are to close for a real gun.....
