Booklice

Humid indoor environments, especially near paper, books, furniture, damp wood, and starchy surfaces.

Microscopic fungi, mold, mildew, starch-based glues (book bindings), and wallpaper paste.

They prefer dark, damp areas with high humidity. They are fast-moving but do not fly, and their presence usually indicates a moisture or mold problem.

They are harmless to humans and pets as they do not bite or transmit disease. However, they can damage old books or contaminate dry food items through their presence; they serve as an indicator that humidity levels are too high.
