Psoroptic mange is an infection with the ear mite, most commonly Psoroptes cuniculi. It is most common in older goats and tends to occur more often in the winter.

Clinical signs presented in infected goats include head shaking, scratching, flaky or scabby lesions or laminated crusts on the external ear or sometimes the poll, pasterns, or back. Often hair loss will occur due to the goat constantly scratching its ear. Yellowish wax is sometimes observed in the ear canal of infected goats.
