Demodex mites are morphologically adapted to this constricted habitat: microscopic, worm shaped, and with very short legs. The mites feed on cells of the epidermal lining of the hair follicle. Many species of mammals, including humans, are readily infested with these mites, but typically the density of infestation is very low.

Dermanyssus gallinae (also known as the red mite) is a haematophagous ectoparasite of poultry.It has been implicated as a vector of several major pathogenic diseases. [1] [2] Despite its common names, it has a wide range of hosts including several species of wild birds and mammals, including humans, where the condition it causes is called gamasoidosis.
