Booklice are soft-bodied, small, and often colorless or pale. They are active in humid conditions and can reproduce quickly. They are generally scavengers and are not considered true pests unless present in very large numbers, indicating a moisture problem.

Generally harmless to humans, though large infestations can contaminate food products or damage books/papers by feeding on mold or glue. Their presence often indicates high humidity and mold growth. They are not known to transmit diseases or bite.
