By building and using corral traps a lot of time, effort, and learning was in my future. Every week something new presented itself. For instance squirrels love to chew ur plywood doors, why, they have a forest full of trees but like ur doors.4x4in square mesh panels are recommended. I built one with 2x2in.square mesh 20 ft long horse panels. Makes a great trap except for the fact if ur inside with a hog whose supposed to be dead that springs to life that 2x2 in square is worthless for a toe hold to scale a fence. If ur my age jumping a 4 or 5 ft fence is a fantasy even with the motivation of a feral hog behind you. Yes in deed, u will learn. 4x4 in squares are highly recommended!!
