More critically, certain species like the body louse act as vectors for dangerous human diseases, including , trench fever , and louse-borne relapsing fever . : They are highly host-specific, meaning most species
: Their eggs, often called "nits," are oval and whitish, cemented firmly to the host's hair. Anoplura and Humans : They are highly host-specific
