Topical medication: For patients with mild symptoms of herpes on skin crawled by insects, mint glycerine lotion, glucocorticosteroid cream (such as dieldrin cream, mometasone furoate cream) and other creams can be applied locally to help astringent, anti-inflammatory, antipruritic and thus effectively alleviate the related symptoms. 3. Oral medication: For patients with more serious symptoms of herpes on skin crawling by insects, oral antihistamines (such as diphenhydramine, loratadine), glucocorticosteroids (such as cortisone, hydrocortisone), and other medications need to be taken on the basis of topical medications to help relieve itching, anti-inflammation, and antiallergenicity. 4. Strengthen protection: In addition to the above treatments, patients also need to pay attention to strengthening personal protection, which can help to achieve better therapeutic effects, such as the use of insecticides to disinfect the environment, when going to the field, pay attention to wear long clothes and long pants, tighten the cuffs and pants, and reduce the contact with poultry and pets, and so on.
