The species of this family are found throughout Europe. Two genera of chigger mites, each containing many species, are of concern to deployed military forces. They are Eutrombicula and Leptotrombidium. Chiggers in the genus Eutrombicula, such as Trombicula alfreddugesi, do not transmit any known pathogens to people, but they can cause irritating bites, dermatitis and severe itching when they feed on the unsuspecting host. They are widely distributed in the Western Hemisphere, and Europe. By comparison chiggers in the genus Leptotrombidium are the vectors of scrub typhus throughout Asia and portions of Australia. The bite of Leptotrombidium often does not itch, or at least not as intensely, as those of Eutrombicula. Also, a black necrotic lesion known as an eschar develops where the chigger fed.[1] References
