Have you ever noticed something skittering across your floor late at night? If you have, it’s likely a house centipede silverfish. These common indoor pests can be unsettling to spot, especially when they start multiplying.
But what’s the difference between them, and how do you deal with these invaders? In this article, we’ll dive into the unique characteristics of house centipedes and silverfish, offering valuable insights into how to keep your home pest-free.
Identifying House Centipedes and Silverfish
If you’re unfamiliar with these insects, it can be easy to mistake them for each other. House centipedes and silverfish share a love for warm, moist environments but differ significantly in appearance and behavior.
House Centipedes: The Multi-Legged Speedsters
House centipedes are a bit of a mystery to many homeowners. These insects have long, slender bodies and can grow to about 4 inches long. With their distinctive fifteen legs—each about as long as their body—house centipedes are incredibly fast and can dart across your floor in a matter of seconds. They are typically brown or tan, with tiny black markings on their exoskeleton. While they might appear menacing, house centipedes are not harmful to humans.
Silverfish: The Shiny, Elusive Pests

Silverfish, on the other hand, are much smaller than house centipedes, measuring just under an inch in length. Their silver, metallic sheen is one of their most distinguishing features, making them easy to spot in low light.
Silverfish have six legs, long antennae, and three tail-like appendages that extend from their rear. Unlike house centipedes, silverfish are secretive and often stay out of sight, making them harder to detect until they’ve already caused some damage.
Habitat Preferences: Where Do They Live?
House centipedes and silverfish thrive in different parts of your home, but they share a preference for dark, damp areas. Understanding where they prefer to live can help you spot the infestation early and take action.
House Centipedes: Finding Comfort in Moist Environments
House centipedes are primarily carnivores, meaning they are on the lookout for other pests to feed on. You’re most likely to find them in bathrooms, basements, crawl spaces, and under-sink cabinets—places where humidity levels are higher. These insects are also fond of areas with an abundance of other bugs, such as cockroaches, spiders, and, yes, silverfish.

Silverfish, however, prefer areas where they can access food. You might find them in your pantry, where they feed on starchy foods like cereals and grains. But their appetite doesn’t stop there! Silverfish are notorious for munching on paper products, glue, wallpaper, and even clothing. If you’ve ever discovered random holes in your favorite books or photographs, silverfish may be to blame.
The Damage: What Do They Do to Your Home?

While both house centipedes and silverfish are pests, they cause different kinds of damage to your home. Knowing what to look for can help you identify which insect is the culprit and guide you in taking the proper steps to eliminate the infestation.
House Centipedes: The Unlikely Heroes
House centipedes are not typically destructive. In fact, they can be considered beneficial, as they prey on other pests that may cause harm to your property. They’ll hunt down and consume spiders, cockroaches, and even silverfish.
Although their speed and appearance may be unsettling, they generally do not cause any damage to your furniture, clothing, or other belongings. However, if you’re uncomfortable with their presence, it’s important to take steps to eliminate them.
Silverfish: A Threat to ow to Remove House Centipedes and Silverfish
While these pests can be disturbing, there are several ways to prevent and remove them from your home. It’s important to tackle the issue quickly to avoid a full-blown infestation.
Eliminating House Centipedes: Keep Them on the Run

Since house centipedes thrive in humid environments, the first step in eliminating them is to reduce moisture levels. Repair any leaks in your plumbing, and use a dehumidifier to reduce humidity in damp areas.
House centipedes also follow the food supply, so controlling other pests in your home, such as cockroaches and spiders, will help deter them. Sealing cracks and gaps in windows and doors will make it harder for them to get inside.
Taking Action Against Silverfish: A Stealthy Approach
Silverfish are trickier to eliminate, as they often hide in dark corners and only venture out to feed. To combat silverfish, focus on controlling humidity levels in your home. Using airtight containers for food and regularly cleaning your pantry can help eliminate their food sources.
You can also use silverfish traps, which are widely available at pest control stores, or make your own using sticky surfaces or baited containers. If silverfish have already caused damage to your books or photographs, consider using a professional pest control service to address the infestation thoroughly.
Stay Vigilant Against Centipedes and Silverfish
Both house centipedes and silverfish can be unsettling, but with the right approach, you can keep these pests at bay. House centipedes are largely harmless and can even help control other pest populations, while silverfish require a more targeted effort due to their potential for damage.
By focusing on moisture control, eliminating food sources, and sealing entry points, you can minimize the chances of an infestation. If you’re unsure whether your home is dealing with centipedes or silverfish, don’t hesitate to call a pest control expert to assess the situation and offer effective solutions. Keep your home pest-free and enjoy peace of mind knowing you’re one step ahead in the battle against these pesky intruders.
