Chorioptic Mites cause a condition known as barn itch or tailhead mange. Taktic (amitraz) or products listed for fly control on animals that contain permethrin as the active ingredient can be used. Two treatments 7 to 10 days apart, or as directed by the label, are necessary for control. Eprinex is labeled for control of chorioptic mange mites with no withholding period for the milk or slaughter.
