You flip on the bathroom light and a small, silvery, teardrop-shaped insect darts across the floor. That's a silverfish, and while it's harmless to people, it's telling you something useful about your Tallahassee home: it's holding too much humidity. In our climate, that's easy to do — and it's the key to getting rid of them.
Why silverfish love Tallahassee
Silverfish are moisture-dependent and thrive in humid, dark, undisturbed spaces — bathrooms, laundry rooms, kitchens, closets on exterior walls, garages, attics and crawl spaces. North Florida's humidity plus air-conditioned homes create condensation pockets that give them exactly what they need. If you're seeing them, there's a moisture source nearby.
The fix starts with drying out
- Ventilate — run bathroom exhaust fans during and after showers; improve airflow in closets and storage.
- Dehumidify — a dehumidifier in persistently damp rooms makes them inhospitable.
- Fix leaks — under sinks, around tubs and toilets, and any crawl-space moisture.
- Declutter storage — remove cardboard and paper piles (silverfish food), and store documents and clothing in sealed plastic bins.
- Seal cracks where they hide and enter.
They're an indicator pest. Silverfish flag excess moisture — and that same moisture invites bigger problems like carpenter ants and the conditions that favor termites. Fixing the humidity protects your home from more than just silverfish.
What they damage
Silverfish feed on starches — paper, book bindings, cardboard, wallpaper paste, glue, and even cotton and linen. Left unchecked, they quietly damage books, documents, wallpaper and stored clothing. For an established population, professional treatment of the harborage plus moisture control is the durable fix. See silverfish control.
Quick answers
Are silverfish harmful?
Not to people — they don't bite or carry disease. But they damage paper and fabric, and they signal a moisture problem worth addressing.
Why do I suddenly have silverfish?
Usually a change in moisture — a new leak, poor ventilation, humid weather, or damp stored items. They multiply where it's consistently humid and dark.
How do I keep them away for good?
Control humidity, fix leaks, ventilate, store paper/clothing in sealed bins, and seal entry cracks. Remove the moisture and they leave.
