Booklouse

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

Starchy pastes, book bindings, mold, fungi, and organic debris.

They are wingless, soft-bodied insects that move in a jerky, scuttling fashion. They thrive in humidity above 60%.

Harmless to humans and pets as they do not bite or transmit disease; however, they can be a nuisance and signal a moisture or mold problem.
