Idk, I think PA hunters could keep them in check. I mean the only thing our state is overrun with are Democrats, which may be a problem for most states. Then again, the PA State Game Commission would probably be able to screw hog hunting up along with most everything else.
No way to keep pigs in check, if you have a 100, you have to kill 66 yearly to break even. That is impossible to do. They reproduce rapidly.
