Silverfish 101: How to Identify, Prevent & Eliminate These Sneaky Pests

We know that few things creep homeowners out more than seeing a shiny, fast little insect dart across the floor at night. Meet the silverfish—one of the oldest insects on earth and one of the sneakiest pests in Morris County homes.

The good news? They don’t bite, sting, or spread diseases. The bad news? They love your books, clothing, wallpaper, and stored food. And once they’re comfortable in your home, they can stick around for years.

This guide gives you everything you need to know about silverfish—what they look like, how to spot the signs of an infestation, what attracts them, and most importantly, how we can help you kick them out for good.

Silverfish Fast Facts

• Ancient Survivors: Silverfish have been around for more than 400 million years—long before the dinosaurs.

• Appearance: Small, wingless, teardrop-shaped insects with silvery-gray scales.

• Lifespan: They can live up to 8 years, making them long-term freeloaders if left unchecked.

• Habits: Nocturnal and fast-moving, which is why you rarely catch them during the day.

These pests may look harmless at first glance, but their persistence and appetite make them an enemy to your belongings.

What Are Silverfish & Why You Should Care

Silverfish are household pests that thrive in dark, damp, and humid areas like basements, attics, bathrooms, and kitchens. While they won’t bite you, they can destroy items you value: books, papers, wallpaper, fabric, and even pantry goods.

Think of them as tiny, stealthy houseguests that leave behind holes, stains, and

shredded materials. They don’t just visit—they settle in.

And here in Morris County, NJ, where many homes have older basements, high humidity, and storage areas full of paper and boxes, silverfish find the perfect environment.

How to Identify a Silverfish Infestation?

The challenge with silverfish is that they’re quick and nocturnal. But if you know the signs, you can spot their presence before the damage gets worse.

• Live sightings: Seeing one dart across the bathroom floor at night is a telltale clue.

• Damage: Look for chewed edges on paper, wallpaper, or cardboard.

• Stains & scales: Yellowish stains and tiny scales may be left behind where they’ve been crawling.

• Droppings: Their droppings look like tiny black pepper flakes.

Not sure if it’s silverfish? Homeowners sometimes confuse them with firebrats, earwigs, or centipedes. If you’re unsure, that’s when professional inspection really helps.

Anatomy & Life Cycle

Silverfish may be small, but they’re survival machines.

• Eggs: Laid in hidden cracks or crevices.

• Nymphs: Hatch looking like smaller adults and continue to molt throughout life.

• Adults: Can live for years, molting even as adults—something unusual among insects.

Because of their long lifespan, a small population today can become a big problem if left untreated.

Behavior, Diet & Environment

Silverfish thrive where there’s moisture, darkness, and food.

• Diet: They love starches, sugars, and cellulose. Think paper, glue, fabrics, wallpaper paste, and even pantry staples like oats or flour.

• Habits: They hide during the day and emerge at night to feed.

• Moisture dependence: Leaky pipes, humid basements, or poorly ventilated bathrooms are prime real estate for them.

• Communication: Believe it or not, they use pheromones to attract each other—making infestations spread.

Prevention: DIY Tips to Keep Silverfish Away

While we always recommend a professional inspection for long-term results, there are several simple steps you can take today to make your home less inviting.

1. Reduce moisture: Use dehumidifiers in basements, fix leaky pipes, and improve ventilation.

2. Declutter: Store books, papers, and fabrics in airtight bins instead of cardboard.

3. Seal entry points: Caulk cracks, gaps, and crevices where silverfish could hide.

4. Clean regularly: Vacuum corners, baseboards, and storage areas.

5. Protect food & valuables: Keep pantry items sealed and protect important papers in storage containers.

Prevention is about making your home less “cozy” for pests, especially in Morris County homes where basements and attics often go unchecked.
