Agri-mectinis injectable, injecting iis best. Some have had success with ivomectin pour on for mites..we never did. Ibtried a few different brands and just did not work for me. Leg mites are imo extra problematic. I would do the injection 1 cc per 40 pounds (safe for pregnant does) once a week for 3 treatments. I would also gently wash the area with a vinegar water mix and try to get the scabs off. Then pat dry and apply ustock.
