How To Avoid House Centipedes from Infesting Your Home

Learn how to avoid centipedes from entering your house and how to keep them away permanently. 

Centipede is a term that refers to a creature with 100 legs, although various kinds of centipede may have as many as 354 legs. Aside from that, centipedes always have an odd number of pairs of legs, which means that none of them have exactly 100 legs.  

What Are House Centipedes? 

Centipedes, also known as house centipedes or Scutigera Coleoptrata, are nocturnal insects. Their bodies are elongated and worm-like, ranging from somewhat white to dark brown, and often have darker patterns. These insects often measure between 1 and 112 inches in length and have 15 pairs of legs. They prefer high-humidity settings, such as basements, closets, or bathrooms, and only go outdoors to find food.  

Because house centipedes are usually solitary, infestations are uncommon. However, they can be found in moist places such as basements, closets, and bathrooms. They are sometimes discovered in bathtubs and sinks. They can also be found in attics and crawl spaces during the warmer months. They are most active at night and can be found hiding in floor drains or under cardboard boxes during the day. 

How to Spot a House Centipede 

The primary distinguishing feature of house centipedes is their profusion of legs. Although the term “centipede” suggests that these animals have one hundred legs, this is not necessarily the case. Instead, the number of legs they have is determined by the number of segments in their body.  

Centipedes in the house usually have thirty legs and two antennas. Their bodies reach a length of approximately an inch to an inch and a half. They also have long legs that extend so far from their body that they nearly look hairy. These centipedes are typically light to medium brown and may have striped backs and legs.  

The presence of silverfish in your home can attract house centipedes. Some people consider house centipedes to be “beneficial pests,” since they consume other pests that you do not want in your home. Centipedes, for example, will gladly consume roaches, flies, termites, and, yes, even silverfish. Nonetheless, most people find these animals repulsive and do not want house centipedes in their homes. 

How to Prevent Future Centipede Problems 

Centipedes enter houses in search of food, humidity, and refuge. Therefore, the most effective method to keep centipedes out is to deny them of such items. There are many methods to do this. Let us learn how to avoid future infestations. 

Reduce Clutter 

Centipedes in your house spend the majority of their time hiding among garbage in moist locations. When they arrive, the fewer sheltering places they have, the less safe they will feel. Clean the inside of your home regularly to guarantee they feel as uncomfortable as possible. Pay particular attention to dark, less-used places. 

Centipedes will seek out protected areas. Eliminating clutter in basements, crawlspaces, and attics reduces their capacity to hide. 

Reduce Moisture 

Centipedes like to dwell in wet, high-humidity settings. To remove these areas, fix water leaks, use dehumidifiers to keep basements dry, and utilize exhaust fans in bathrooms and attics to assist in removing excess moisture. 

While addressing the source of the humidity is an excellent starting step, it is not always sufficient enough to resolve the issue. For example, certain parts of your building can remain naturally humid. In such instances, a dehumidifier is recommended. 

Reducing humidity to normal indoor levels effectively eliminates the ability of house centipedes to live in your structure for extended periods. In general, appropriate humidity management is critical for preventing long-term or continuing centipede infestations. A dehumidifier is one of the simplest and quickest methods to do this. 

Seal Cracks and Crevices 

Centipedes do not need much room to enter. That is why it is critical to immediately seal cracks, holes, and gaps in your property. Begin by identifying simple entry points in places where your centipedes are likely to dwell indoors. 

Inspect your garden level, basement, storage room windows, baseboards, concrete flooring, and foundation. Gaps and fractures surrounding utility lines should be sealed, particularly if they lead into your furnace or boiler room. Check for drafts, then attempt to identify and fix the source of those drafts. Not only would this eliminate insect entry points, but it will also help decrease the humidity, which is what draws centipedes, to begin with. 

Seal any holes, fissures, or gaps around the outside of your home to keep centipedes and other insect pests out. Repairing screen rips and installing weather stripping to doors and windows also helps keep out undesirable bugs. 

Remove Their Source of Food 

By the way, these unsightly home centipedes are predators. As previously said, these predators consume a variety of insects in our houses that most people despise, ranging from tiny spiders to cockroaches. Therefore, if you remove their food supply, centipedes will eventually seek food elsewhere. 

Traps are another effective technique of removal and are readily available in most shops. Several insecticides work against fleas, roaches, bed bugs, ants, and even earwigs. Even some carnivorous plants can eat pests, so adding extra greenery to your house may not be a terrible idea. 

Sprinkle Salt 

Salt is an excellent natural repellent for centipedes. Sprinkle salt around damp spots or gaps in the walls to prevent them from entering your house. If you have pets, you may want to put salt around their water bowls. However, make sure that your dogs do not eat the salt!  


If the problem continues and a more severe step is required, consider contacting professional pest management or pest control services. We hope you avoid going down that path and that the issue can still be resolved early on using the methods we just provided. Best of luck!
