Maggots removed from the wound should be buried deep or burned to avoid becoming adults. Peppermint oil can also be applied to the wound, which can make the maggots fall quickly from the wound and be completely maggot-free after 1 hour.

(2) Avermectin or ivermectin is injected subcutaneously at 0.2 mg per kilogram of body weight, which can kill the larvae in the nasal cavity or in the sinuses.

(3) Preparation of aqueous solution of enemy worm alcohol intramuscular injection to take refined enemy worm 60 grams, 95% medical alcohol 31 ml, distilled water 31 ml, miscible. Sheep weighing less than 20 kg should be used for 0.5 ml, 20 to 40 kg should be used for 1 to 1.5 ml, 40 kg should be used for 2 ml, and 50 kg or more should be used for 2.5 ml.
