I do a significant amount of night hunting myself, but I sincerely think we are barely scratching the surface of the hog problem this way. I don't see any way a person could shoot enough with his night vision to make an impact on the hog population. I do more with my traps by a long shot....and I don't think I am making any meaningful impact that way either. I don't know what the answer is...but I think the hogs are gaining population on a regular basis.
Yep! What Old Stony said!! Thousands of sows birthing 14 piglets twice a year means we aren't ever going to catch up with them by hunting them at night. Traps; large traps; set correctly and visited regularly can make a big dent in a local population. But unless a whole bunch of people make the financial and time requirement commitment to trapping, the feral hog will continue to win.
