If you have a problem with hogs on your land, selecting the proper trap design is your best solution. In many parts of the Southern United States, specifically Texas and Alabama, feral hog populations are become a large problem. The populations of these pests are growing rapidly and their encroachment on human farms and gardens is disastrous. These animals are capable of total destruction of corn fields and gardens, in addition to posing a danger to humans and domestic animals.
Trapping hogs is not a simple task, and several factors must be considered. You have to be aware of the different types of traps. Some are designed for hunters and sportsmen. Some are made for large boars, but most can only handle small pigs. Understanding your particular problem will let you know what kind of trap to select.
The most common type of trap is a simple wire frame with a root door. Several sheets of strong metal wire should be welded together with an opening left for a door. This should be the size you expect your largest hog to be. A root door is simply an angled door that can be pushed from the outside but no the inside. Once the hog is in, it is there to stay. Make sure your trap has a wire frame on the bottom as well. Hogs can dig out through the ground and escape the trap otherwise.
To create the root door, simply cut a sheet of wire frame that will fit properly into the opening and will not allow the animals to escape. It should be long enough that it cannot be pushed straight from the inside. Next, attach the door at the top with a simply hinge.
This will give you a hog trap that can capture multiple hogs at once. After you have caught the pigs, you can pay to have them removed or in some states they can be used for meat.
