Booklouse (or Psocid)

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

Feed primarily on microscopic mold, fungi, starches, and organic debris found in damp materials.

Photophobic (light-avoiding) and very active crawlers; they do not fly or jump. They reproduce rapidly in humid conditions and are often seen when storage items are disturbed.

Harmless to humans and pets as they do not bite or transmit disease; however, they are considered a nuisance pest and can occasionally damage stored food or book bindings in large numbers.
