Booklice

Damp, warm environments such as bathrooms, kitchens, leaky pipes, or among old books and papers with high moisture content.

Microscopic mold, fungi, starch from book bindings, and organic debris.

They are nocturnal or shade-loving insects that thrive in humidity over 60%. They do not fly and move in quick, jerky bursts when disturbed.

They do not bite or transmit disease; however, they are considered nuisance pests and their presence is an indicator of high humidity and potential mold growth.
