What are the key differences between booklice and bed bugs in terms of appearance, behavior, and preferred habitats?

Booklice are tiny, pale insects with soft bodies that feed on mold and fungi found in damp areas like books and wallpaper. They do not bite humans and are not harmful. Bed bugs are reddish-brown, flat insects that feed on blood and can be found in bedding and furniture near where people sleep. They bite humans and can cause itchy welts. Bed bugs are more commonly found in homes and hotels, while booklice prefer damp environments.
