They are a real PITA here in eastern PA as well. We had them living under a pre-cast front stoop pretty much every year. I tried chicken wire, expanded metal, and various foul smelling substances to deter them. I'll bet I hauled around 10 of them out, but never in the Shelby. I finally got smart and drilled holes in the stoop and filled it with concrete. Haven't had one since.
I was told you have to take them at least 5 miles away or they will find their way back. Don't know if that's true but....
