Missouri is getting a population of feral hogs in the southern part of the state, I know of a lot of guys killing them around the Lesterville and Centerville area, but they are pretty hard to hunt form what I hear. The Dept of Conservation wants them shot on sight so they dont become a problem. It is rumored that a bunch of hogs were released in the area a few years ago when hog prices went to nothing, maybe some people wanted something new to hunt, there is supposed to be a lot of them there, but are very nocturnal and skittish.You dont have to have a tag, except when it is deer season, oyu have to have a deer tag, I think you may have to have a hunting liscense, but no tags and no limits, they want them gone.
