160s work great for skunks, usually right behind the neck catch and most times no spray but at times when they relax when dying the gland muscles relax and release some scent. 220s are to large and get skunk on shoulders a non killing catch. Ive caught and killed skunks in 120s set for mink, never moved out of box used for mink and 120s. the triggers are all all the way to the side OR bent up in a t close to top of trap... this gives open view for skunk to put his head in and bang! Good luck and happy skinning.
