Booklouse

Damp, warm areas with high humidity, often found in books, pantries, and behind wallpaper.

Microscopic fungi, mold, starchy pastes, and organic debris.

Non-flying and fast-running insects that thrive in high humidity; they reproduce rapidly in favorable conditions but are not social insects.

Harmless to humans and pets, but can be a nuisance and may indicate a moisture or mold problem in the home.
