In their relentless march across the country, pigs plow through crops, tear up roads and infrastructure, spread disease, and elbow native species out of fragile marshes, riversides, grasslands, and forests. Many researchers consider them the most destructive invasive species on the planet. Live trapping and euthanizing feral hogs is an effective method for removing large numbers of hogs. Trapping requires developing a strategy and persistence to be successful. The steps for effective feral hog trapping are: Pre-baiting at multiple sites to locate hogs on trails cameras, baiting and drawing them into a location suitable for trap placement, building up a trap suitable for capturing a number of animals, and triggering the trap.
