Booklouse (Barklouse)

Humid indoor environments, libraries, pantries, and damp wallpaper

Starchy pastes, book bindings, mold, fungi, and microscopic organic debris

Nocturnal scavengers that seek out high humidity; they reproduce quickly in damp conditions and do not fly

Harmless to humans and pets but can be a nuisance or cause minor damage to paper goods and dry food stores
