You flip on the bathroom light and see a small, silver insect dart under the sink. Or maybe you’ve spotted one in your bedroom or closet and wondered: Why am I getting silverfish in my home?
Silverfish prefer dark, sheltered areas where access to moisture and food is easy. In the Pacific Northwest, our damp climate makes homes especially inviting.
Where you find silverfish can offer clues about what’s attracting them. Here’s what to watch for and when it might be time to look into professional silverfish control.
Why Am I Getting Silverfish?
Silverfish look for three basic things: moisture, food, and places to hide. Humidity, leaks, condensation, and poor ventilation create the perfect conditions. Silverfish feed on materials containing starches and carbohydrates. This includes things like paper, cardboard, book bindings, wallpaper adhesives, and some stored foods. Add cracks, crevices, and undisturbed storage areas, and these pests have everything they need.
What Does the Location of Silverfish Tell You?
Where you spot silverfish may just give you a clue to what’s attracting them. Here’s a room-by-room breakdown:
- Bathrooms: Bathrooms naturally provide humidity and moisture. If you’re seeing silverfish activity in your bathroom, you may want to check the ventilation, plumbing, and the areas around your sinks or tubs for excess moisture.
- Bedrooms: Bedrooms offer plenty of hiding places for silverfish.
- Kitchens: Kitchens provide just what silverfish need to survive and thrive: food and moisture.
- Basements and crawl spaces: Basements and crawl spaces are dark, quiet, and potentially damp, which can make them especially attractive to silverfish.
- Closets and storage areas: Closets and storage areas house cardboard boxes, old papers, books, and other items that sit undisturbed, which can provide both shelter and potential food for silverfish.
Is It Safe to Sleep in a Room With Silverfish?
It’s not unsafe to sleep in a room with silverfish. These pests aren’t known for biting people or spreading illnesses. But despite their more innocent nature, repeated sightings shouldn’t be ignored.
If you’re seeing silverfish consistently, take a closer look at your environment. Check for excess humidity, inspect closets, cardboard storage, books, baseboards, and other dark or undisturbed areas. The silverfish itself may not be a threat to you, but repeated activity can indicate that the room (or an area nearby) is providing the perfect conditions.
Does Seeing One Silverfish Mean You Have an Infestation?
Not necessarily. A single silverfish may have wandered in randomly. Repeated sightings are a lot more telling. If you see silverfish in the same area, notice them in several rooms, or find damaged paper or other organic material, there might be a larger population hiding nearby.
Keep in mind that silverfish are nocturnal and decent at hiding. If you’re spotting more than one of these pests, the odds are high that there is more happening behind the scenes.
What Should You Do When You Find Silverfish?
The first thing you should do if you spot a silverfish in your home is check the area for excess moisture. This type of issue isn’t just about pests. Letting moisture gather where it shouldn’t can be a health hazard and a danger for your home and family; termites and mold are real risks.
If silverfish keep appearing but you haven’t found a common attractant, widen your search. A leaky pipe, a humid crawl space, a poorly ventilated bathroom, or another moisture problem can contribute to the infestation.
