Ever spotted a silvery bug darting across your bathroom floor? If so, you might be sharing your home with silverfish—a common but pesky insect that loves dark, damp, and cluttered spaces. Learn how to spot, remove, and prevent these unwelcome guests for good!

You’re brushing your teeth, half awake, when a fast-moving, shiny bug scurries across the bathroom floor like it owns the place. Disgusting, right? If you notice these little critters more than once, you’re likely facing a silverfish infestation. These slippery, fish-shaped insects are exactly as odd as they sound.

So, what do silverfish mean for your home, how do you recognize them, why are they invading, and most importantly—how do you get rid of them once and for all?

What Exactly Are Silverfish?

Silverfish are tiny, wingless insects that have been crawling the earth for millions of years. Seriously—these bugs are prehistoric! Measuring around 1½ inches in length, their bodies are flat, taper at the end, and are covered in shiny, silver scales. With their long antennae and distinct wiggling movement, they look both odd and unsettling. If you’ve seen one, you know the feeling.

Don’t worry—they can’t fly or bite. But that doesn’t mean you should ignore them.

Why Silverfish Have Moved In

Spotting silverfish in your home—whether it’s the bathroom, basement, kitchen, or laundry room—means your house offers everything they want. Silverfish are drawn to:

Humidity: They thrive in damp places. Darkness: They avoid light at all costs. Starch and sugar sources: Paper, glue, cardboard, fabric, and food crumbs.

That’s right—these bugs love carbs! They’ll chow down on book bindings, wallpaper paste, old newspapers, and even dandruff (believe it or not).

Are Silverfish Dangerous?

Silverfish don’t bite or carry diseases, but don’t be fooled by their calm nature.

If left unchecked, silverfish can cause significant damage, especially to:

Books & paper – They’ll eat the glue and the pages. Clothing & linens – Long-stored items are especially vulnerable. Wallpaper – They’re after the paste! Food – Especially pantry items like flour, oats, and cereal.

Even worse, they breed quickly. A couple of silverfish can turn into a real problem in just a few months.

How to Tell If You Have Silverfish

Besides seeing them dash across the floor, other signs include:

• Yellow stains or small holes on paper or fabric
• Shedded skins—silverfish molt and leave their shells behind
• Droppings—look for tiny black specks in dark, hidden corners
• Wallpaper damage, especially along seams and edges

If you spot any of these signs in damp areas, you’ve got silverfish.

How to Eliminate Silverfish

Ready to send silverfish packing? Here’s your action plan:

1. Eliminate Moisture
Silverfish can’t survive in dry spaces. Use a dehumidifier—especially in basements and bathrooms—and make sure there’s good ventilation.

2. Remove Their Food Sources
Declutter! Clear out stacks of paper, cardboard boxes, and books in damp rooms. Keep pantry staples in airtight containers. Vacuum often, especially in forgotten corners.

3. Block Their Hiding Spots
Seal up cracks, gaps, and crevices along baseboards, pipes, and walls. Fewer places to hide means fewer bugs.

4. Try Natural Repellents
Diatomaceous earth is a natural powder that kills silverfish by damaging their exoskeletons—sprinkle it where you’ve seen them. Boric acid works too, but keep it away from pets and kids. Lavender, citrus, and cedarwood scents can also help repel them (plus your home will smell great!).

5. Set Simple Traps
A jar wrapped in masking tape (so they can climb in) with a bit of bread inside can catch silverfish. They get in, but can’t get out.

6. Call Pest Control
If you’re seeing lots of silverfish, especially during daylight, it’s time to call the professionals for a thorough extermination.

How to Prevent Silverfish from Returning

Once they’re gone, keep them out!

* Use moisture absorbers like DampRid under sinks and in closets.
* Store paper and clothing in plastic bags.
* Avoid letting clutter and crumbs accumulate.
* Keep your home dry, tidy, and well-ventilated.

A dry, clutter-free space will convince silverfish to look elsewhere.

Silverfish may be icky, but they’re not uncommon. These survivors love moisture and starch—and while they aren’t dangerous in the traditional sense, they can be a huge nuisance. With the right approach, you can identify, remove, and keep them away for good.
