When unexpected guests like the house centipede or silverfish invade our homes, it’s natural to feel uneasy. These common household pests share a preference for dark, damp environments and are known for their quick movements, making them hard to ignore. But while they may seem similar at first glance, their behaviors and the problems they cause are very different.
The house centipede is a predatory insect that feeds on other pests, such as cockroaches, spiders, and silverfish, playing an unintentional role in reducing pest populations. Silverfish, however, are scavengers that prefer starchy materials, causing damage to paper, fabrics, and even pantry items. This makes silverfish more destructive, while house centipedes are often a sign of other pest activity.
Understanding these differences is crucial to managing infestations and protecting your home. Whether you’re dealing with the quick, leggy house centipede or the destructive silverfish, proactive measures can help you maintain control. Let’s explore what sets these pests apart and how Alta Pest Control can help you address their presence effectively.
House Centipede vs Silverfish: Key Differences and How to Manage Them
House centipedes and silverfish are common household pests, but their differences in appearance, size, and behavior make it easier to identify and address each one. Recognizing these distinctions is the first step to managing infestations effectively.
Appearance
The house centipede has an elongated, flattened body with dark longitudinal stripes and bands on its legs. Its grayish-yellow coloration and sprawling appearance make it unmistakable. In contrast, the silverfish has a shiny, smooth texture and a uniform gray or silver color. Its sleek body gives it a more compact, streamlined look compared to the leggy house centipede.
Size and Legs
House centipedes are larger, reaching up to 1.5 inches in length. They possess 15 pairs of long, slender legs that fan outward, giving them a wide, sprawling appearance. Silverfish are smaller, typically 0.5 to 1 inch long, with six short legs that keep their movements compact and less pronounced. The house centipede’s many legs are a clear distinguishing feature.
Behavior and Movement
House centipedes are hunters, using their speed and darting motion to chase down prey like cockroaches, spiders, and other insects. Their predatory nature often makes them a sign of other pest activity in your home. Silverfish, on the other hand, are scavengers that feed on starchy materials like paper, fabrics, and stored food. Their unique wiggling motion, reminiscent of swimming, sets them apart from the rapid, darting movements of house centipedes.
While both pests thrive in damp environments, their differing behaviors and eating habits highlight why each requires a specific approach to control. Alta Pest Control is here to help identify and manage both pests effectively, ensuring your home stays free of these unwelcome guests.
Habitats and Locations
House centipedes and silverfish often seek out similar environments but have distinct preferences that reflect their behaviors. Both pests thrive in dark, damp, and secluded areas, though their specific habitats vary based on their needs.
Where House Centipedes Live
House centipedes are commonly found inside homes, especially in areas with high humidity, such as basements, bathrooms, and crawl spaces. These spaces provide the ideal environment for their predatory behavior, offering easy access to prey like spiders, ants, and even silverfish.
Outdoors, house centipedes may reside under rocks, leaf piles, or in compost, but they are more likely to migrate indoors when temperatures drop or food sources become scarce. Once inside, they are often spotted in dark, undisturbed spaces like closets, under sinks, or behind furniture. Their preference for high-humidity environments means they are most active in areas with water leaks or poor ventilation. House centipedes are nocturnal and known for their darting, rapid movements as they hunt their prey.

Where Silverfish Live
Silverfish also favor damp environments but are more closely tied to areas with organic materials and starches. Basements, bathrooms, and kitchens are common hotspots, as are spaces where starchy items like paper, cardboard, or fabric are stored. Attics, laundry rooms with piles of clothes, and closets with books or old documents are also prime locations for silverfish.
Outdoors, silverfish can be found hiding under rocks, in bird nests, or beneath tree bark. However, they frequently migrate indoors during unfavorable weather conditions, seeking warm, humid spaces with limited airflow. Unlike house centipedes, silverfish move more slowly and in a characteristic wiggling motion, often found near bathroom floors or pantry shelves, where they scavenge for food.
Potential Risks and Damage
Understanding the risks associated with house centipedes and silverfish is essential for protecting your home and maintaining peace of mind. While neither pest is particularly dangerous, their behavior and potential to cause damage are notably different.
Do They Bite?
House centipedes have the ability to bite using their modified claws, but such incidents are extremely rare. Their venom is designed to subdue prey and is not harmful to humans, though a bite might cause mild irritation or discomfort at the site. Silverfish, on the other hand, do not bite or sting, making them entirely non-threatening in terms of physical harm.
Are They Harmful to Humans?
House centipedes are often considered helpful because they hunt and reduce other pest populations, like cockroaches and spiders. However, their rapid and unexpected movements can cause alarm for homeowners. Silverfish pose no direct threat to humans, but they can indirectly affect your well-being by contaminating food products or causing damage to personal belongings. This can lead to frustrations and unnecessary expenses if left unaddressed.
Property Damage
House centipedes do not damage property or belongings. Their presence is typically a sign of other pest activity, as they prey on insects that might already be causing problems.
Silverfish, however, are more destructive. They feed on materials containing starch, sugars, or cellulose, which includes books, wallpaper, fabrics, cardboard, old photographs, and even stored grains or paper currency. Over time, this can lead to noticeable damage to your possessions and stored items. Addressing silverfish infestations promptly is essential to avoid costly property loss.
How to Prevent and Remove Infestations
Preventing and removing house centipedes and silverfish doesn’t require a severe infestation to warrant action. Whether you’ve spotted a few pests or simply want to take precautionary steps, combining preventive measures, DIY techniques, and professional pest control can help keep your home pest-free.
Preventive Measures
Professional pest control isn’t just for severe infestations—it’s a proactive way to keep pests out before they become a problem. At Alta Pest Control, we recommend addressing the conditions that attract house centipedes and silverfish, including:
- Reducing Humidity: Fix leaks, use dehumidifiers, and ensure proper ventilation to eliminate the damp environments these pests thrive in.
- Decluttering: Regularly clean and organize spaces like basements, closets, and storage areas. Store books, papers, and fabrics in sealed containers to remove hiding spots and food sources for silverfish.
- Sealing Entry Points: Inspect walls, doorframes, and utility entry points for gaps or cracks. Use caulk or weatherstripping to block access and prevent pests from entering your home.
While these steps are helpful, professional pest control offers long-term solutions tailored to your specific needs. Our quarterly treatments ensure pests are kept at bay year-round, providing an added layer of protection.
DIY Removal Methods
DIY methods can help with mild infestations, but they often require significant time and effort and may not fully address the root cause. Common techniques include:
- Sticky Traps: Placing traps near entryways or areas of pest activity can capture house centipedes and silverfish, offering visible evidence of their presence.
- Diatomaceous Earth: Sprinkling this natural powder around baseboards, cracks, and damp areas creates a barrier that dehydrates pests on contact.
- Natural Deterrents: For silverfish, scents like cedar, cloves, lavender, or cinnamon can repel them and disrupt their nesting habits.
- Vacuuming Hidden Areas: Regular vacuuming of cracks, crevices, and cluttered spaces helps remove eggs and live pests.
While these methods may reduce pest numbers temporarily, they rarely offer the same lasting results as professional pest control. DIY solutions often address the symptoms of infestations rather than the underlying causes, leading to wasted time and money.
