Silverfish in Alabama
Those wriggling, silver, teardrop-shaped insects in your bathroom or bookshelf are silverfish — a classic humidity pest in Alabama homes.

How to identify silverfish
Silverfish are 1/2"–3/4" long, silvery-gray, teardrop-shaped, with three long tail bristles and a fish-like wriggling movement. Firebrats are similar but mottled and prefer warmer spots near water heaters and pipes.
Behavior in Alabama
They thrive in damp, dark places — bathrooms, basements, crawlspaces, attics, and around plumbing. They feed on starches: paper, book bindings, wallpaper paste, cardboard, and natural fabrics. Alabama’s humidity gives them ideal conditions.
Why silverfish are a problem
Signs of silverfish activity
- Silvery insects darting from light in bathrooms
- Yellowish stains or tiny holes on paper & fabric
- Pepper-like droppings in storage areas
- Shed skins near books and boxes
When they’re active
Active year-round indoors; most noticeable in humid summer months and in chronically damp areas.

Why do I have silverfish in my bathroom?
Silverfish need humidity. Bathrooms, basements, and crawlspaces hold the moisture they thrive in. Reducing dampness — along with treatment — is key to controlling them.
Are silverfish harmful?
They don’t bite or carry disease, but they damage paper, books, wallpaper, and stored fabrics, and signal a moisture problem worth addressing.
