Picture this: you pull out an old book from your shelf, ready to enjoy a classic read in your favorite armchair, and out darts a small, wriggly, silvery creature.
Startled, you wonder, “What on Earth is that?”
Chances are, you’ve just had an encounter with a silverfish. These nocturnal insects are known for their shimmery, fish-like appearance and quick movements.
But are they dangerous? And more importantly, do silverfish bite? Let’s settle this once and for all while learning a bit more about these little critters most of us would rather pretend don’t exist.

What Are Silverfish?
They’re usually about 12–19mm long and have a shiny, metallic appearance, which is where their name comes from. Their flattened, carrot-shaped bodies make them excellent at squeezing into impossibly small crevices, and trust us, they love their hidey-holes.
Silverfish primarily come out at night, thriving in dark, damp environments. They’re common in basements, attics, under sinks, and even inside your walls.
Their diet consists of carbohydrates and sugars, which means they’ll chow down on starchy materials like book bindings, wallpaper glue, and even your favorite cereal if given the chance.

Do Silverfish Bite Humans?
That said, while silverfish won’t bite you, they can cause some indirect trouble. They might nibble on personal belongings, leaving damage that’s annoying to deal with. Imagine finding chew marks on a beloved photo album or holes in clothing, not fun.
It’s also worth mentioning that, although they don’t pose any physical harm, their presence may trigger allergies in sensitive individuals. Their shed skins and droppings can mix with dust, creating allergens that trigger sneezing. While they won’t bite, those with respiratory sensitivities might find silverfish living rent-free a real pain. For expert exterminators Lees Summit, contact us today!
How Big an Issue Are Silverfish in the Home?
These sneaky creatures may not pose immediate harm, but they can certainly wreak havoc on your belongings over time. Here’s why you won’t want them as permanent roommates.
1. They Damage Your Belongings
Silverfish are notorious for destroying items made of paper, cloth, and other starchy materials. Think old cardboard boxes, photographs, cherished books, or even that perfectly aged leather jacket resting in your closet. If left unchecked, these tiny pests can cause a surprisingly big headache.
2. They Reproduce Quickly
While a single silverfish may feel manageable, it’s essential to know that these insects reproduce rapidly. If you don’t address the problem quickly, you could soon find yourself dealing with a full-blown infestation.
3. They Attract Other Pests
Silverfish are also pest bait. Their droppings can attract other insects, like cockroaches, spiders, or centipedes, into your home. Basically, it’s like throwing an all-you-can-eat buffet for other pests not ideal, to say the least.
How Do You Spot a Silverfish Problem?
Spotting silverfish is often easier said than done, as they’re nocturnal and love secluded spaces. However, here are some key signs you may have them lurking in your home:
- Shedded Skins: These bugs molt throughout their lives, leaving behind tiny, papery skins.
- Chewed Items: Look for small holes or nibbled edges on books, wallpaper, upholstery, or old photos.
- Droppings: Silverfish leave behind tiny, black, pepper-like droppings near areas where they’ve been active.
- Actual Sightings: If you’re lucky (or perhaps we should say unlucky), you may spot them darting out of your pantry or near your sink when you flip the lights on at night.

How Can You Prevent or Eliminate Silverfish?
Thankfully, dealing with silverfish is easier than you might think. Here are some tips to prevent or get rid of them:
Reduce Humidity
Since silverfish thrive in damp environments, reducing humidity is key. Use dehumidifiers in musty rooms, repair any leaks, and make sure your home is well-ventilated.
Seal Cracks and Gaps
Stop them from entering by sealing cracks in doors, windows, walls, and baseboards with caulking or weatherstripping.
Eliminate Their Food Sources
Store books, old clothing, and papers in sealed plastic bins. Wipe up crumbs and spills quickly to avoid attracting these pests.
Use Natural Remedies
Cedar oil and diatomaceous earth are natural remedies that can deter silverfish. Sprinkle these around potential hiding spots for a non-toxic solution.
