Booklouse

Damp and warm environments such as libraries, kitchens, under wallpaper, and in pantry items

Starchy materials, mold, mildew, book bindings, and dried grains

Scavengers that thrive in high humidity; they reproduce rapidly and are often found in large numbers but are not true lice as they do not feed on blood

Harmless to humans and pets as they do not bite or transmit diseases, but can be a nuisance and potentially cause minor damage to books or food supplies
