Mold mites is a general term that refers to a variety of
mites (e.g. members of the families Acaridae, Pyroglyphidae, Tarsonemidae) found in association with fungal growths such as mildew, moldy grain, and spoiled food. Many of these mites also are common in house dust. Most mold mites feed directly on
molds, and typically require microbial growth to develop, but others also eat the substrates supporting fungal growth. Common mold mites include the cheese mites (perhaps the most common being Tyrophagus putrescentiae, a member of the Acaridae), the flour mite Dermatophagoides farinae (a pyrogylphid mite related to a common house dust mite of temperate regions, D. dermatophagoides), and the
grain mite Acarus siro (Acaridae). In the older literature, mold mites are sometimes called tyroglyphid mites, derived from the obsolete family Tyroglyphidae.
