So here in Texas, wild hogs are not considered game animals and are a non-native species. You can shoot them any time of the year you want without a license. That is one reason why some people like to hunt them. Some people hunt for meat, some just want to get rid of them. How does that work for your state?
My boss lives in a neighborhood with 1 acre lots. He has them come into his yard digging up the grass. However, I think if he shoots one occasionally, they don't come around so often. If no one in his neighborhood ever shot one, I can see them getting pretty bold.
I have driven by a group of several hogs several miles up the road. There easily could be some that live in some sanctuary land near my neighborhood. I do have a possum that comes through my yard occasionally. I heard they eat stuff I don't want so I don't mind that.
