I like the old trap and whack en masse principle
Most of the trappers I know use the "trap and sell" principle.
I think trying to eliminate hogs is like trying to eliminate coyotes. A lost cause. I choose to see hogs as a new game animal (and kind of a dangerous one). There are a bunch on my deer lease near Davis. We shoot and eat them, but we aren't into slaughter or waste. I know that's legally okay, but since they seem to be here to stay, we are treating them like they belong. We have fenced them out of the deer feeders, and we are considering fencing some food plots, because they tear tham up real bad.
I am hoping to kill a big boar this winter so I can have a European mount for the wall, but otherwise we harvest eaters. They have eaten most of the rattlers and copperheads (seen two this whole year, one of each), apparently all the skunks, definitely all the quail eggs, but none of the armadillos. I really think they sould simply be seen as a new part of the environment.
I have witnessed a good bit of what I see as animal cruelty. One example is a guy who gutshoots them with a .22 pistol from his deer stands so they'll "go off and die." I am a long way from a PITA member (yes, I know how it's really spelled), but ugly or not, welcome or not, hogs feel pain just like a deer or a dog does.
Just another perspective. I do love to hog hunt, but don't think hunting ethics should be ignored. CB
