Silverfish in Books and Papers: How to Protect Your Collection

Silverfish love the starch in book bindings, glue and paper, so libraries, files and old photographs are at risk.

The short answer

Silverfish chew irregular holes, surface scrapes and yellow stains on paper, book covers and photographs. Protect your collection by controlling humidity, storing items in sealed boxes or cabinets off the floor and away from walls, and checking regularly. Isolate affected items, clean shelves and ask a conservator or professional for valuable pieces.

Signs of damage

• Irregular holes and ragged edges.
• Scraped surfaces and thin patches.
• Yellow stains and tiny droppings.
• Live silverfish when books are moved.
