As I mentioned before, they love cedar trees to rub on for the insect repellent, but they also love creosote poles too, as the creosote on light, and telephone poles works great also. Land_Owner mentioned their socializing with each other, and it extends to pigs that are still sucking. If their mother dies, another wet sow will let them suck. Their hard to get rid of, once the infestation takes hold. Their wilder, smarter, and tougher than any coyote or deer, and they will eat anything, including coyotes, their pups, deer, and their fawns, and even each other. They also have far bigger litters than either deer or coyotes, and can also decimate the squirrel, and turkey population by eating all the mast, and the turkey eggs.
