Booklouse

Damp, dark areas with high humidity, often found in books, pantries, and under wallpaper.

Feed on mold, fungi, starches, and organic debris found in household items.

They are wingless, fast-running insects that thrive in environments with 60% or higher humidity.

Harmless to humans and pets as they do not bite or transmit disease, but can be a nuisance and may damage starch-based glues in books.
