Booklouse

Found in warm, humid indoor environments, particularly around books, paper, pantries, and damp walls.

Feeds on microscopic molds, fungi, starchy book bindings, wallpaper paste, and dry stored food products.

They are wingless, run very quickly, and reproduce rapidly via parthenogenesis in warm, humid conditions.

They do not bite, transmit disease, or damage wood, but large infestations can contaminate stored foods and indicate high indoor humidity.
