Booklouse

Found in warm, humid indoor environments, damp walls, old books, and stored pantry items.

Feeds on molds, fungi, starchy book bindings, wallpaper paste, and dry organic debris.

Runs quickly rather than jumping, highly sensitive to humidity, and reproduces rapidly via parthenogenesis.

Harmless to humans and pets, does not bite or transmit disease, but heavy infestations can damage books, paper goods, and stored food.
