Booklice

Damp, warm environments with high humidity; often found in books, papers, food pantries, and behind wallpaper.

Microscopic fungi, mold, mildew, starch-based glues (like those in book bindings), and occasional grain products.

They are wingless, fast-running insects that thrive in humidity above 60%. They do not undergo a larval stage, instead hatching from eggs as miniature versions of adults (nymphs).

They do not bite humans or pets and do not spread disease. They are primarily nuisance pests that indicate a moisture or mold problem; they can cause minor damage to stored paper products or contaminate dry food goods.
