The PGC website had some info on the before id ont knwo about now though. They had on there that they are not a game species and you do not need a license to hunt them for some reason i dont remember why. Im sure they will change that when a bunch of people start hunting them. As for stopping them from taking over that is not going to be easy at all. I lived in Alabama for a few years and they took over my moms 65 acres in about 6 months the place was destroyed.
