Booklouse

Natural Habitat

Damp, warm environments often found in libraries, poorly ventilated pantries, or under wallpaper where mold grows

Diet & Feeding

Feed on microscopic fungi, mold, algae, and starchy materials like book binding glue

Behavior Patterns

Prefer high humidity (above 60%) to survive as they derive water from the air; they are wingless and move with a jerky, scuttling motion

Risks & Benefits

No risk of biting or disease transmission to humans, but can cause minor damage to books and stored dry goods; mostly considered a nuisance indicator of moisture issues
