Ectoparasites are organisms that live on the external surface of a host. The term "ectoparasite" is a broad category encompassing a wide range of creatures that include insects, arachnids, and even some other invertebrates. These parasites derive nourishment from their host, often by feeding on blood, skin, or other tissues. Their presence can cause a variety of issues for the host, ranging from minor irritation to severe disease.

Common examples of ectoparasites include fleas, ticks, lice, and mites. Fleas are small, wingless insects that are adept jumpers, often infesting mammals like dogs, cats, and rodents. Ticks are arachnids that attach themselves to the skin of hosts and feed on blood, and are known vectors for diseases like Lyme disease. Lice are also insects that infest the hair and bodies of humans and animals, feeding on blood and causing itching. Mites are microscopic arachnids that can cause skin conditions such as scabies in humans and mange in animals.

The lifecycle of ectoparasites typically involves several stages, often including eggs, larvae, nymphs, and adults. Reproduction rates can be high, leading to rapid infestations if not controlled. Transmission between hosts can occur through direct contact, contaminated environments, or shared objects. The impact of ectoparasites on animal health, agriculture, and public health is significant, necessitating effective prevention and treatment strategies. Understanding the biology and behavior of these organisms is crucial for managing their presence and mitigating their effects.
