Combating Paperfish: Natural Solutions for Home & Archive
They're small, nimble, and usually unnoticed: Paper worms are silent destroyers in our living spaces, libraries, and archives. These inconspicuous insects prefer to feast on paper, wallpaper paste, or book spines and can cause significant damage over time – especially to valuable documents or collections. If you discover them, you should act quickly. But don't worry: There are effective, environmentally friendly solutions you can use to combat paper worms naturally.
An overview of the pest
Paperfish ( Ctenolepisma longicaudata ) belong to the Pistachio family and are closely related to the more familiar silverfish. Unlike silverfish, paperfish prefer dry, warm environments. They are 8 to 15 mm long, have no wings, and move jerkily. Particularly noteworthy is that they can live up to eight years – and during this time, they can spread unnoticed.
They probably originated in warmer regions and, thanks to modern heating technology and construction, have now established themselves in Central European households. They are crepuscular and nocturnal, which makes their early detection difficult.
Life cycle and behavior
A single female lays up to 200 eggs in her lifetime. Under ideal conditions—temperatures between 25 and 30 degrees Celsius and low humidity—the larvae develop into sexually mature individuals within six months. A special feature of this species is that they molt up to 50 times in their lifetime, even after reaching maturity. This makes them particularly resistant to many control strategies and poses a real challenge.
How to recognize an infestation
A paperfish infestation often goes unnoticed for a long time. Therefore, look out for the following signs:
- Damage to paper, cardboard, labels or book spines
- Moulting residues or small dark crumbs on shelves and drawers
- Sightings of the animals at night in crevices or corners
- Faded or damaged print images on documents
As soon as you notice one or more of these symptoms, we recommend targeted observation using attractant traps.
Natural methods to combat
Effective and ecological pest control is possible – without the use of chemicals. The following methods have proven particularly effective:
- Glue traps with attractant: For detecting and controlling an infestation.
- Plastic pheromone traps: Reusable and durable – ideal for long-term control.
- Diatomaceous earth: A fine, natural powder that destroys the insects' protective layer and dries them out.
- Essential oils: Lavender oil, in particular, has a deterrent effect and can be vaporized in affected areas.
- Reduce humidity: Ventilate regularly and avoid overheated, dry rooms – this inhibits reproduction.
- Avoid dust and paper accumulation: Keep potential food sources as low as possible.
Preventive measures
Once freed, you'll certainly want to keep paperfish away permanently. These simple measures will significantly increase your chances:
- Store documents in well-sealed plastic containers
- Check bookshelves, cracks and drawers regularly
- Sealing gaps and cavities
- Replace traps regularly – also for prevention
- Keep rooms clean and dry
- Minimize thermal bridges – for example through targeted insulation
Through consistent prevention, you can protect your rooms in the long term and without great effort.
