Imagine as you enter your bathroom one night, and you spot little creatures scurrying around the space. You turn the light on, and they very quickly scatter and skirt under the boards, your bathtub, and inside the drains. That’s a horror scene you don’t want in your bathroom, but unfortunately, it can happen.
These small, gray insects are silverfish, one of the oldest creatures on the planet. They were already here for thousands of years, and while they are not the scariest-looking insects out there, they are not the common sight you want around your bathroom.
Good thing you can get rid of silverfish naturally or by using chemicals that can keep these unwanted guests off of your bathroom, for good.
What Should You Know About Silverfish
Silverfish are bluish silver or white to brown-gray, wiggly insects that can infest your bathroom. They have a shiny, teardrop-shaped body with two antennae and three long bristles at the tail end. This six-legged insect is often mistaken for a centipede and can grow between 12 to 19 millimeters.
You might get horrified seeing these wriggly bugs in your bathroom, but they are pretty harmless. Silverfish aren’t known to pose threatening diseases, and they don’t bite either.
Still, they are pests and can cause damage to your bathroom. Silverfish feed off of sugars and starches, and some of your bathroom essentials contain these ingredients.
For instance, toilet paper contains starch, and you might be using sugar scrubs in the bath too. So they can start feeding off of the outer edges of your toilet paper, sugar-container products, your bathroom wallpaper, and even carpets and clothing.
Silverfish are active at night, and you may see them scurrying around the bathroom floor or climbing the bathroom walls in the middle of the night. So, you’ll not likely see them in the daytime.
In favorable conditions, like a highly humid bathroom, silverfish can reproduce quickly as the female insects produce eggs all year. In addition, because they are secretive and can go unnoticed for an extended period, it allows silverfish for exponential growth all year-round.
How Do Silverfish Get Into Your Bathroom
These wiggly insects will enter your bathroom through torn screens, gaps in the window, and through wall and foundation cracks.
If you have gaps and holes in water pipes, silverfish will likely go through these entryways and end up in your drains and sink.
Unfortunately, silverfish infestation can also happen in your bathroom because of unintentional transmission.
These insects love paper products, and they can take refuge in any paper or boxes you bring inside your washroom.
For instance, you brought an old journal already infested with silverfish eggs in the toilet or a box of toilet paper stored improperly in the bathroom.
If you spot some silverfish in your bathroom, the reason can be one or a couple of these things.
- Damp conditions in the bathroom
- Dark and warm spaces
- Lack of cleanliness
Silverfish love moisture, dampness, darkness, and quiet. These conditions make bathrooms the most favorable for silverfish, making it their best place to hide, sleep, and breed.
You can usually spot them in high-humidity areas in your bathroom, like the shower. If you love taking hot showers, the steam can significantly increase your bathroom’s humidity levels.
If your toilet has many warm and moist spaces, an attractive breeding ground for silverfish, they can start invading your space.
The lack of strict cleanliness in the bathroom can also attract silverfish inside your space. Dirt and crumbs in your bathroom are like inviting silverfish to feast on your area and take their refuge there.
Where Can You Find Silverfish in Your Bathroom
Since they are nocturnal insects, silverfish will be sleeping and hiding during the day, and you can find them in their usual hiding places like the:
- Bathroom Drains
Most people believe that they live in drains, but that is far from the truth. Contrary to common belief, silverfish don’t live in drains. But they do love the moisture, warmth, and darkness of toilet drains.
You can see silverfish that climb bathroom walls, but they can’t climb smooth vertical spaces, like the bathtub or the sink. So, you can frequently find them trapped in drains.
- Wall Cracks and Crevices
Besides the bathroom and shower drains, their favorite hiding places include the tight cracks and crevices in your bathroom. Any dark opening where they can enter freely would be an ideal place for silverfish to hide inside.
- Under the Carpet
If you have an old and dirty carpet in your bathroom, you can sometimes find silverfish taking refuge underneath.
Bathroom pipes that have condensation on them are also attractive hiding spaces for silverfish. If you have a leaky pipe in the bathroom, perhaps under the sink, you might find silverfish hanging in there.
- Under Clothes and Fabrics
Silverfish love clutter and they also feed on starches. It’s why any layer of clothing or fabric on the floor will be inviting to them.

Here, you can find a couple of steps to minimize and eliminate silverfish infestation, whether you want to do it the natural way or using chemicals to take them out for good.

Step 3: Wait for the silverfish to feed on the newspaper and hide inside it. Eventually, they will get trapped in the rolled paper.
