Ectoparasites are parasites that live on the outer surface of their host, such as on the skin, hair, or feathers. They can include a variety of organisms, such as mites, ticks, fleas, lice, and bedbugs, among others. Ectoparasites can cause a range of problems for their hosts, including skin irritation, itching, and the transmission of diseases. Treatment for ectoparasites may involve the use of medications, such as insecticides or acaricides, as well as measures to prevent reinfestation, such as regular cleaning and grooming. It is important to consult a healthcare professional or veterinarian for appropriate diagnosis and treatment of ectoparasitic infections.
