They breed like dogs, a couple litters a year. This expands the population quickly. Kill the little ones too. Gut em, skin em, loose the head, cut em in half down the spine with a saws-all and throw em on the grill. MMMmmm, good eats.
They are fun to hunt. They come to tainted corn (put in a water filled bucket covered for a week) or you can stalk em if you play the wind right. They don't see well at all. Be ready for a 2nd shot on a 2nd pig. They stay in groups, when one squeals (after a shot) others may come to help. They scatter like idiots when spooked, be ready to sidestep around a tree if being charged. They are fast but can't turn quickly.
Don't use a single shot. I was muzzleloader hunting on State property and found a few. I shot at one and they all ran in different directions. One looped around and was coming straight for me (not on purpose, just running) and all I could do was get around a tree. No follow-up shot that quick with the ML. He just continued his loop and ran off. I missed the one I shot at.
