Why Do I Get Silverfish?  

04 June 2024 · 3 min read


Have you ever wondered why those pesky silverfish always seem to find their way into your home? It’s all about creating the perfect environment for them – the mix of warmth, humidity, and plenty of tasty snacks to munch on. While they may not be the guests you invited, understanding what attracts them can help you keep them away. Let’s dive into the intriguing world of silverfish and discover what lures them into our homes. Additionally, how to keep them from making themselves at home. 

Ideal Living Conditions for Silverfish 

Creating the perfect environment for silverfish is like rolling out the red carpet for these little critters. They thrive in warm, humid areas, so think of them as the ultimate cozy dwellers of your home, ideally between 70°F and 80°F. From the steamy bathroom to the neglected corners of your basement, they seek out darkness and moisture.  

Picture this: after a hot shower, the bathroom becomes a silverfish paradise, especially if ventilation is lacking. And let’s not forget about the basements and attics, where humidity can hang in the air, offering an irresistible invitation to these pests. Come nighttime, these nocturnal creatures emerge from their hiding spots to forage for food, making these ideal living conditions for them. 

Sources of Food 

Silverfish have quite an appetite and aren’t picky eaters. They feed on a wide variety of materials, thanks to their ability to digest complex carbohydrates. Here’s what’s on their menu:  

Starch and Carbohydrates

Silverfish love starchy foods like pasta, cereals, flour, and sugary snacks. If you’ve ever found tiny holes in your cereal box or nibbled on pasta, you’ve probably had a visit from silverfish.  

Paper and Glue: Books, wallpaper, and cardboard boxes are like gourmet meals to them. They particularly enjoy the glue that binds books and the paste behind wallpaper.  


Fabrics such as cotton, linen, silk, and even synthetic fibers are fair game. They can cause damage to your clothes, upholstery, and carpets.  

Dead Insects and Organic Matter

Silverfish are not above munching on other dead insects or organic debris they find around your home. That’s why it’s crucial to keep areas clean and free of food particles and clutter that could provide a feast for these pests. 

How Do Silverfish Enter Homes? 

Ever wondered how those pesky little silverfish manage to invade your home? These sneaky critters are experts at slipping through cracks, gaps, and even plumbing to make their way into your living space. They’re so slender that they can squeeze through the tiniest of openings in walls, windows, and doors. Plus, they can hitch a ride through plumbing pipes and pop up in your bathroom and kitchen drains, surprising you in your sink or tub.   

Once they’re inside, silverfish are like ninja masters of hiding. They’ll set up camp in your walls, behind baseboards, under sinks, and in any other dark, secluded spot they can find. Their talent for hiding and their nocturnal habits make them incredibly elusive.  

So, the next time you bring home second-hand items or storage boxes, be sure to give them a thorough inspection before welcoming them into your space. You never know if those little stowaways might be lurking within.
