around my area the ranchers handle them themselves by trapping and (then) shooting. for "residential" livestock problems, the county will send a trapper in. about three years ago the county mounty was called to the area, he was VERY effective, and it has taken about three years to notice a significant comeback for the local yotes. as others said, dogs work great to keep the herd safe, but if you want them dead expert trapping is probably best.
