Overrun with beasties
For mites or lice I would spend $2.75 or so for a quart of plain-jane motor oil, pour a little across the pig's shoulders and then pour a little down the base of their neck to the base of their tail. (Make a cross on them.) That oil will get all over them in about half an hour and will kill eggs and bugs without hurting your pig in the least.
