Because scratching is nature's treatment for ectoparasites, they should be considered in the differential diagnosis of any pruritic rash. Usually, the diagnosis is not difficult to make if the clinician suspects an ectoparasitic cause and is familiar with the symptoms and signs of these disorders. The diagnosis is confirmed using a few instruments and basic office supplies. The clinician must treat not only the individual patient but must also consider the source of the infection because others may require treatment. Family and community education about removal of the parasites from the patient's environment is one of the clinician's responsibilities.
由于搔抓是机体对抗体表寄生虫的方式，因此在对任何瘙痒性皮疹进行鉴别诊断时都应考虑到体表寄生虫感染。通常，如果临床医生怀疑是由体表寄生虫感染所致，且熟悉这些疾病的症状和体征，那么做出诊断并不困难。使用一些仪器和基本的门诊用品即可确诊。临床医生不仅要治疗个体患者，还必须考虑感染源，因为其他接触者可能也需要治疗。临床医生的职责之一是对患者家属和社区进行教育，告知如何清除患者生活环境中的寄生虫。
