Booklice

Damp, warm environments such as between the pages of old books, under wallpaper, in pantries, or in moldy warehouses.

Microscopic fungi, mold, mildew, starchy pastes used in bookbinding, and occasionally cereal grains or animal-based fragments.

Gregarious and fast-moving, they prefer dark areas and high humidity (above 60%). They do not fly and lack wings in many common indoor species.

They do not bite humans or pets and do not spread disease. They are primarily a nuisance pest that can cause minor damage to books or contaminate stored dry goods; their presence is often an indicator of high moisture or mold problems.
