Treatment
Animals that are clinically affected with any of the forms of mange described should be treated without delay. The most effective treatment is injectable Avermectin and in severe chronic cases a double treatment 10-14 days apart is appropriate.
Historically, topical organophosphates were used but these are no longer available. Similarly, topical amitraz is no longer licensed for used in pigs.
In pigs close to slaughter, the prolonged meat withdrawal periods associated with the above products may preclude their use. In such cases, in feed Avermectin can be used.
