Trap designs for wild pigs include box traps, cage traps, corral traps and snares. Certain states require special licenses to use specific traps. Since snares are prone to capturing non-target wildlife species and domestic animals, it is illegal to use them in some states.
Box traps are square or rectangular wooden constructions with a door and trigger mechanism. Usually, box traps have no top or bottom panel. Trappers can prevent side entry and escape by securing the box to the ground. Box traps are low cost, collapsible and easy to assemble.
Cage traps consist of heavyweight livestock wire panels with an angle iron and/or square tubing frame. A spring loaded trap door encloses the prey. The wire construction presents a more open appearance that is less intimidating to wildlife. While rectangular cage traps are the most common, trappers also utilize circular cage traps for easier portability. Some cage trap designs include top and bottom panels to prevent escape, but they are not always necessary and can prevent the escape of non-target species.
While box traps and cage traps are ideal for small numbers of prey, corral traps are better for trapping groups of prey. However, corral trap construction can take more time and require more effort than other trap designs. Corral trap shapes and sizes vary, but circular designs prevent animals from piling up in corners and escaping over the open top. Materials used to construct corral traps include livestock wire panels, t-posts, u-bolts and zip ties. The height of the walls and trap doors needs to account for pig jumping capabilities.
A snare consists of an anchored wire loop that tightens around the prey. While snares are inexpensive, effective and portable, they are made for one-time use and can be lethal and cruel to prey.
