Short answer: Those teardrop-shaped, silvery insects darting across your Milton bathroom or pantry are silverfish, and they're here for two things: humidity and starch. Our muggy Gulf Coast summers give them the damp air they need, and paper, book bindings, cardboard, dry food, and natural fabrics give them the meal. Lower the humidity and cut off the food, and you make your home a lot less welcoming.
Silverfish thrive in warm, humid spaces and hide in cracks, closets, bathrooms, and storage boxes. They feed on materials high in starch, sugar, or protein — paper, glue in book bindings, cardboard, cereals, and cotton or linen. Cluttered, damp storage areas are prime real estate, which is why you often first notice them in a bathroom cabinet or a box in the garage.
The single most effective step is drying things out: run exhaust fans and a dehumidifier, fix plumbing leaks, and ventilate closets and storage. Store paper goods, dry food, and off-season clothes in sealed bins instead of cardboard. Declutter the damp areas where they breed. Because silverfish tuck into deep crevices and are active at night, professional crack-and-crevice treatment and baiting reach them where surface sprays can't.
Are silverfish harmful? They don't bite or carry disease, but they damage belongings — chewing paper, photos, book bindings, wallpaper paste, and natural fabrics. The damage adds up in stored boxes over time.
Why do I keep seeing them in the bathroom? Bathrooms give silverfish exactly what they want: humidity and tight, dark hiding spots. Improving ventilation and lowering moisture makes the room far less suitable.
Can I get rid of them for good? Yes, but it takes cutting the humidity, removing food sources, and treating the cracks where they live and breed. Moisture control is the piece most do-it-yourself efforts miss.
