FAQ
Frequently Asked Questions
No. A 'bookworm' refers to the larvae of certain beetles that bore through paper, or figuratively to a keen reader. A 'booklouse' (psocid) is a different, smaller insect that feeds on mold and microscopic organic matter, not the paper itself.
No. Booklice are not parasitic and do not bite, sting, or transmit diseases to humans. They are considered a nuisance pest that can damage collections by feeding on molds and possibly glues or starches.
They thrive in damp, humid conditions with mold growth. Common locations include old books, damp wallpaper, stored cereals, and in the bindings of neglected volumes in basements or poorly ventilated rooms.
Control focuses on reducing humidity (dehumidifiers), improving ventilation, removing moldy materials, and thorough cleaning. Insecticides are rarely needed and are not recommended for use directly on books or archives.
