Booklouse

Found indoors in damp, warm areas, libraries, pantries, and under wallpaper where mold thrives.

Feeds on microscopic molds, fungi, starch, paste, and book bindings.

Nymphs and adults are wingless and avoid bright light. They reproduce rapidly in humid environments without mating via parthenogenesis.

Harmless to humans and pets, and do not transmit disease, but heavy infestations can damage stored foods, paper, and book collections.
