Booklouse

Damp, warm environments with high humidity, often found in books, paper, wall coverings, and stored food products.

Microscopic fungi, mold, algae, and starchy organic materials like book bindings and wallpaper paste.

Gregarious insects that thrive in high humidity; they are wingless and move with a characteristic jerky, running motion.

Harmless to humans as they do not bite or transmit disease, but can be a nuisance and cause minor damage to paper goods and stored dry pantry goods.
