Booklouse (or Psocid)

Damp, warm environments with high humidity; often found in books, pantries, or under wallpaper.

Microscopic fungi, mold, starch, and organic detritus.

Fast-moving and light-avoiding insects that prefer high-moisture conditions to prevent desiccation.

Harmless to humans and pets as they do not bite or sting; primarily a nuisance pest that indicates high indoor humidity or mold issues.
