Need a good source of renewable food after SHTF, look no further then the wild hog. Wild hogs have invaded all of the lower 48 states, Texas alone has an estimated 1.5 million feral hogs.
The problem is, the hogs are mean, can be difficult to trap, can injure or kill hunting dogs, and can be difficult to transport.
Trapping Wild Hogs
Hog traps are only limited by your imagination. They can include anything from a box trap to a pen trap.
The usual hog trap is made out of welded angle iron, and is 4 feet wide and 8 feet long. The door is spring loaded so that when a hog enters the trap, the door closes behind them. Some traps are rigged so that the door opens while the hog is rooting around the edge. The hog pushes the door open, the hog goes into the trap, and the door closes behind the hog.
Hog traps are not that difficult to build, all you really need is the materials, cutting torch or saw, and a welding machine.
Most people use corn to bait the traps.
In some cases hogs will not enter the trap. When that happens, wire the door open for a couple of weeks so the hogs can go in and out of the trap.
