Hog Lice and Mange Mites
External parasites of swine include the hog louse and two species of mange mites (the common itch mite and the less common hog follicle mite). Excessive scratching and rubbing by pigs nearly always indicate an infestation of hog lice or mange mites.
Hog lice and mange mites infest a high percentage of swine slaughtered at Midwest slaughter plants.
