RE: How can I get rid of these things???????
In Tx if you kill a hog they are pretty much like coyotes in that you can leave them lay. Hogs tend to move in and out of areas pretty frequenlty, especially on small acreage like yours. So perhaps one day the hogs will disappear, they tend to go where the food and/or water is at. In your case I would personally stop feeding corn and get reid of the mineral block. That should make the pigs move out of the area. I would also continue trapping as much as possible and I would have a "shoot on site" policy towards the pigs.
