Trapping is probably the most effective feral hog control technique available for most land managers. Other control methods, such as aerial gunning and ground hunting, can be relatively dangerous or not very effective, according to Drovers CattleNetwork.
Many trap technologies are available, including cage or box traps, circular spring panel traps, corral traps, drop nets, the new remote watch-and-set BoarBuster and others. The key is to match the trap to the size of the feral hog sounder, so to trap the entire sounder at one time.
A sounder is a herd of feral hogs primarily comprised of one or more adult sows and one or multiple generations of offspring. Feral hogs are relatively intelligent and can learn quickly, so a portion of a sounder remaining outside a tripped trap often learns to avoid the trap.
Cage or box traps can be effective management tools when dealing with small sounders of less than six individuals or individual boars. When dealing with sounders comprised of more than six individuals, larger traps such as corral traps, drop nets or the BoarBuster are more appropriate.
