Booklice can be found in books or paper stacks feeding on

• A. Leather
• B. Fungi & mildew
• C. Wood
• D. Pollen

Answer: (B)

Booklice thrive where mold and mildew are present on paper. Their feeding is focused on fungi that grow on damp pages, glue, and bindings, so their diet is essentially fungi and mildew. They’re not typical feeders on leather, wood, or pollen, which is why those materials aren’t their natural food sources. This means that seeing booklice in books or paper stacks usually points to damp conditions with mold growth. To reduce or prevent infestations, address moisture and mold—dry out the area, improve ventilation, and remove or thoroughly clean moldy materials, then store papers in dry, well-ventilated spaces.
