A snare is a mechanical devise made of a cable loop and sliding locks. A hog snare captures a feral hog around its neck or leg. As the animal puts pressure on the sliding locks, the loop tightens and prevents the hog from escaping. In order to snare a hog, you must have the proper equipment, set the snare in the proper location and position it to capture the size of hog you desire.
Items you will need
Galvanized steel cable snare with locking slides, 1/8-inch
Stopping device
Anchor
Swivel
Locate a hog trail. Hogs are creatures of habit that walk the same trails in search of food. This is especially true if there is a constant supply of food in several different areas. Be aware that hogs use trails that other game or domestic animals may also frequent. Find a trail that is hog-specific, if possible.
Find the proper location for your snare on the trail. Snares work best when a hog is forced to walk through a confined area. Choose an area between bushes or trees, under a fence, around a rock outcropping, a body of water or over obstacles.
Set the snare. Fasten the swivel on the end of the cable to an anchor such as a fence post, tree, a T-anchor driven into the ground or anything else that can withstand the pressure of a mature hog pulling on it. Suspend the loop of the snare from a single-wrapped, light-gauge piece of wire or two that can break away from the suspension point. Set your suspension point between 1 1/2 feet and 3 feet high. Suspension points can be a limb, a piece of wire on a fence, a nylon cord run between two objects or a stiff piece of wire wrapped around an object and hung horizontally over the trail. Set the loop size and elevation on the snare. Set the loop between 1 foot and 2 1/2 feet in diameter. The size of the loop depends on the size of hog you expect to snare.
