Booklouse

Damp, humid environments such as basements, crawl spaces, and areas with high moisture; often found in books, pantries, and under wallpaper.

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

Non-jumping, wingless insects that thrive in high humidity; they reproduce rapidly in favorable conditions and are often seen scurrying in large groups.

They do not bite humans or pets and carry no diseases, but high populations indicate a moisture or mold problem and can contaminate stored dry foods.
