Booklice

Damp, warm environments such as under tree bark, in leaf litter, and indoors in humid areas like pantries, bookshelves, or bathrooms.

They feed primarily on microscopic fungi, molds, starches (such as glue from book bindings), and organic debris.

They are scavengers that prefer high-humidity conditions; they do not fly and move in quick, jerky motions. They undergo incomplete metamorphosis (egg, nymph, adult).

They do not bite or transmit disease to humans. While they can be a nuisance or cause minor damage to stored products or old books, they are generally harmless and act as indicators of high humidity and potential mold growth.
