Booklouse

Damp, dark, and humid environments like old books, pantries, wallpaper, and areas with mold growth.

Starchy pastes (book binding glue), mold, mildew, fungi, and microscopic organic debris.

They are wingless, fast-running insects that thrive in high humidity; they reproduce rapidly in favorable conditions but do not bite humans or pets.

Harmless to humans but can be a nuisance and cause minor damage to stored paper goods or food; their presence serves as an indicator of high household humidity/mold.
