Eliminating entire sounders (groups) of feral hogs is the only way to effectively control the problem.
The most cost efficient way to accomplish that is through remote controlled electronic trapping. Dogs will catch a few and run the rest off only to come back weeks later. Mechanical triggered traps will catch a few and educate the rest.
HFAC professionals will evaluate your individual situation, bait and then effectively remove all sounders affecting your property or lease.
