Why Centipedes are Found in Homes

Centipedes, often recognized by their numerous legs and elongated bodies, belong to the class Chilopoda. These arthropods can range in size from a few millimeters to 12 inches, depending on the species, and they typically inhabit dark, damp environments. Recently, homeowners have reported an uptick in centipede sightings within their living spaces. This has raised eyebrows and concerns alike, prompting many to question why these creatures, which are usually confined to gardens and outdoor spaces, are making their way indoors.

Understanding Centipedes in Homes

Centipedes, with their multi-legged appearance and swift movements, often evoke reactions of surprise and unease when spotted inside homes. Yet, to better address the issue of their presence, one must delve into their habits, lifecycle, and preferences. This understanding not only demystifies the centipede but also provides insights into why they might choose our homes as their dwelling place.

Brief Overview of Centipede Habits and Lifecycle

The daily activities and lifecycle stages of centipedes are intricately tied to their environment and their predatory nature.

What Do Centipedes Typically Feed On Inside Homes?

Primarily carnivorous, centipedes are adept hunters. In natural settings, their diet consists of insects, spiders, and other small invertebrates. When they venture into domestic settings, their palate adapts but remains carnivorous. They’ll actively hunt and consume household pests such as cockroaches, silverfish, and even spiders. This positions them as natural pest controllers, albeit unintended ones. While their appearance might be alarming, their dietary habits can inadvertently aid in keeping other pest populations in check.

What Is the Lifecycle of a Centipede in a Domestic Environment?

Centipedes, irrespective of where they live, follow a distinct lifecycle. After a mating process, female centipedes deposit their eggs in damp and protected areas. These could range from soil pockets to hidden crevices within homes. Depending on the species, a single female might lay anywhere from 60 to 150 eggs.

Upon hatching, the young centipedes, known as larvae, initially bear a resemblance to adults but with fewer leg pairs. As they grow and mature, they undergo multiple molting stages. With each molt, they acquire more leg pairs, gradually approaching their species’ characteristic appearance. It’s crucial to note that the domestic environment, often devoid of natural predators and characterized by stable conditions, can be conducive for their growth. In such settings, centipedes have been known to live for several years, with certain species even reaching up to six years in age.

Are There Regions or Countries More Prone to Centipede Invasions in Households?

Geography plays a significant role in the distribution of centipedes, and some regions are indeed more susceptible to household centipede invasions. Warm and tropical climates, characterized by consistent moisture and abundant prey, provide the most conducive environments for centipedes. This is why countries in Southeast Asia, Central and South America, and parts of Africa often report higher instances of centipedes in homes. However, centipedes are versatile creatures and are found on every continent except Antarctica. Even in temperate zones, the presence of basements, crawl spaces, or any moisture-rich environments can attract centipedes, making household encounters possible.

How Do Centipedes Adapt to Living Indoors Versus Their Natural Habitat?

Centipedes are resilient creatures, and their adaptability is a testament to their evolutionary success. In the wild, they gravitate towards dark, damp spaces, such as under logs, rocks, and leaf litter, which offer them protection and a steady source of prey. When they transition to indoor environments, they seek out similar conditions. Basements, bathrooms, or any spaces with plumbing leaks can recreate the humid and dim environment they favor.

Inside homes, their diet adjusts based on available prey. As mentioned earlier, household pests like cockroaches, ants, and silverfish become their primary food source. Another significant adaptation is their nocturnal behavior. Being active mainly during the night allows them to avoid potential human interactions, and it’s also when many of their prey species are active.

However, it’s important to note that while they can adapt, homes do not provide the optimal environment for centipedes. They might face challenges related to lower prey availability, dry conditions (especially in air-conditioned spaces), and direct threats from humans or pets. As such, their presence indoors is often a temporary detour rather than a permanent shift from their natural habitat.

Attraction Factors: Why Centipedes Choose Residential Spaces

Understanding the allure of residential spaces for centipedes involves considering the specific conditions and elements present in our homes that might inadvertently invite them in. These factors are not just limited to the structure of the home, but also the habits of its inhabitants.

Conditions That Favor Centipede Infestations

Homes can unknowingly provide an environment that either mimics or supplements the natural habitats of centipedes, making them ideal places for these arthropods to venture into.

How Does the Moisture Level in a Home Impact Centipede Presence?

Moisture is perhaps the most significant attractant for centipedes. These creatures are naturally drawn to damp environments, which not only provide the hydration they need but also favor the proliferation of their prey. In residential spaces, high moisture levels can be found in areas like basements, bathrooms, laundry rooms, and anywhere there may be leaks or poor ventilation. Humid climates, in general, can see more centipede invasions due to the ambient moisture. Homes with persistent dampness, whether due to structural issues or environmental factors, often find themselves more prone to centipede visits.

Can Over-Watering Indoor Plants Contribute to Attracting Centipedes?

Absolutely, over-watering indoor plants can indirectly invite centipedes inside. The excess water in plant saucers, combined with the organic matter of the soil, creates a microhabitat that can attract various pests, including fungus gnats and springtails. These small pests can, in turn, lure in centipedes searching for prey. Moreover, the moisture retained in the soil can create a conducive environment for centipedes to hide and thrive. Thus, maintaining a balanced watering schedule and ensuring proper drainage for indoor plants is essential not just for plant health but also for preventing unwanted guests like centipedes.

Relationship Between Centipedes and Other Pests

Centipedes and other pests often share a complex relationship, particularly within domestic settings. The presence of one can influence the other, either directly or indirectly.

Can the Presence of Other Pests in a Home Attract Centipedes?

Yes, the presence of other pests can indeed be a major attractant for centipedes. Being carnivorous, centipedes primarily feed on insects and smaller pests. A home infested with insects like ants, cockroaches, or spiders can be a food haven for centipedes. Consequently, when they sense an abundant food source, they might be drawn into homes more readily. In essence, a pest problem can lead to or signal a subsequent centipede issue.

Are There Benefits to Having Centipedes in the Home, Such as Controlling Other Pests?

While their appearance might be off-putting to many, centipedes do offer a silver lining: they can help control other pests. By feeding on insects and smaller pests, they naturally reduce the population of those unwanted creatures in the home. In a way, they act as a natural pest control, mitigating potential infestations of more harmful or disruptive pests. However, while this predatory behavior can be beneficial, most homeowners would prefer a home free of both pests and centipedes. 

Climate Considerations

Climate plays a pivotal role in the behaviors, habits, and movements of centipedes. Their presence in homes can be directly or indirectly influenced by the larger climate or even minute seasonal variations.

How Does Climate or Weather Affect the Presence of Centipedes in Homes?

Centipedes prefer warm and humid environments. As such, homes located in tropical or subtropical regions might experience more frequent encounters with these arthropods. But it’s not just the overall climate that matters. Short-term weather patterns, like prolonged rains or sudden temperature drops, can drive centipedes indoors in search of shelter and stable conditions. In contrast, homes in dry or cold regions might see fewer centipedes, unless the indoor environment offers them the warmth and humidity they crave.

How Do Seasonal Changes Impact the Frequency of Centipedes in Homes?

Seasonal shifts, particularly the transition from warm to cold weather, can influence centipede behavior. As the temperatures drop, centipedes might seek refuge inside homes to escape the chill. Additionally, the rainy season can increase the moisture level in the environment, making homes more inviting for these moisture-loving creatures. Conversely, during hotter and drier periods, if homes provide a cooler and more humid refuge compared to the scorching outdoors, centipedes might also be tempted to move in. In essence, any drastic shift in outdoor conditions that makes the indoor environment comparatively more favorable can result in a spike in centipede presence.

Entry Points: How and Where Centipedes Infiltrate Our Homes

Though homes are built as sanctuaries for humans, many creatures, including centipedes, often find ways to breach these protective barriers. Understanding how they manage to infiltrate can provide insights into effective prevention strategies.

How Do Centipedes Enter Homes?

Centipedes, with their flexible bodies and numerous legs, are adept at exploiting even the tiniest of gaps to gain entry into homes. Common entry points include:

  • Cracks and Crevices – Foundations, walls, and the areas around windows and doors can develop minute cracks which centipedes can squeeze through.
  • Vents and Drain Pipes – Open or poorly screened vents and drain pipes can serve as direct pathways for centipedes into homes.
  • Under Doors – The gap between the bottom of a door and the floor, especially in older homes, can be wide enough for centipedes to slide through.
  • Brought in Unintentionally – They can occasionally hitch a ride on plants, outdoor furniture, or other items brought inside.

Do Certain Types of Homes or Construction Materials Make It Easier for Centipedes to Infiltrate?

Yes, the type of home and the materials used can influence the ease with which centipedes gain entry. Older homes, which might have settled over time, often develop cracks or gaps that can invite these pests. Homes made with certain types of stone or wood might naturally have more crevices, which can provide entry points. Moreover, homes that lack a solid foundation, like those built on stilts or with crawl spaces, can be more susceptible to centipede invasions due to the easy access provided to ground-dwelling creatures.

Do Centipedes Prefer Specific Areas or Rooms in a House?

Centipedes have a strong preference for damp, dark spaces. Consequently, they’re often found in:

  • Basements – The typically cool and moist environment of a basement is highly attractive to centipedes.
  • Bathrooms – Given the inherent humidity and the frequent presence of water, bathrooms can be a hotspot for these arthropods.
  • Kitchens – Areas under sinks or around leaky pipes can provide the moisture centipedes seek.
  • Laundry Rooms – Similar to bathrooms, the humidity and occasional water spills make laundry rooms appealing.
  • Garages and Storage Rooms – These areas can mimic the dark, undisturbed outdoor environments centipedes are accustomed to.

Understanding these preferences can guide homeowners in their efforts to deter centipedes, focusing on making these specific areas less inviting for these many-legged invaders.

The Impacts and Risks of Domestic Centipedes

Centipedes, while fascinating, can bring a mix of benefits and concerns when they find their way into our homes. Here, we dissect the potential impacts, the risks, and the misconceptions surrounding these critters in a domestic setting.

What Are the Risks or Dangers of Having Centipedes in Your Home?

Contrary to some beliefs, centipedes, especially the common house centipede, are relatively harmless to humans. However, there are a few concerns associated with their presence:

  • Bites – While rare, some larger species of centipedes can bite if threatened. Their bite might cause localized pain, redness, and swelling, similar to a bee sting in its intensity.
  • Allergies – Some individuals might be allergic to centipedes or the substances they release. In such cases, an encounter can lead to more severe reactions.
  • Psychological Discomfort – Many people find centipedes unsettling or even frightening due to their appearance. Their presence can thus cause anxiety or distress.
  • Indicator of Other Pest Problems – As discussed earlier, centipedes feed on other pests. Their presence might indicate an underlying pest issue in the home.

Relationship Between Pet Ownership and Centipedes

How Do Pet Ownership and the Presence of Centipedes in a Home Correlate?

Pet ownership can influence the centipede dynamics in a household in various ways:

  • Food Source – Pet food, if not stored correctly, can attract other pests, which, in turn, can invite centipedes.
  • Water Bowls – Pets’ water dishes can provide the moisture that centipedes seek.
  • Predation – Cats and some dogs might hunt and kill centipedes, acting as a deterrent for these critters.
  • Introducing Centipedes – Pets, especially those that spend time outdoors, might inadvertently bring centipedes into the home on their bodies or in their bedding.

Overall, while pets can introduce factors that attract centipedes, they can also serve as a line of defense against them.

Common Misconceptions About Centipedes in Homes

  • Danger to Humans – Many believe all centipedes are venomous and dangerous. In reality, most species found in homes pose little to no threat to humans.
  • Infestation – A single sighting of a centipede might be misinterpreted as an infestation. However, centipedes are solitary creatures, and seeing one doesn’t necessarily mean there are many more.
  • Disease Carriers – Some people mistakenly think centipedes carry diseases. Unlike some other pests, centipedes are not known to transmit any diseases to humans.
  • Attraction to Filth – It’s a myth that centipedes are attracted to dirty homes. They are primarily in search of moisture and prey, not dirt or waste.

Understanding these misconceptions can help homeowners approach the presence of centipedes in their homes with a balanced perspective, addressing the situation with knowledge rather than fear.

Prevention and Deterrence

As the saying goes, “Prevention is better than cure.” This is especially true when it comes to household pests like centipedes. By understanding their habits and taking preventive measures, homeowners can greatly reduce the likelihood of a centipede invasion.

Effective Ways to Prevent Centipedes from Entering a Home

  • Seal Entry Points – Regularly inspect the foundation, walls, windows, and doors for cracks or gaps and seal them using caulk or other suitable materials.
  • Reduce Humidity – Invest in dehumidifiers for damp areas of your home, like basements or attics. Ensuring good ventilation can also help keep moisture levels in check.
  • Fix Leaks – Regularly check and repair any leaky pipes, faucets, or roofs to prevent moisture buildup.
  • Store Firewood Away from Home – Centipedes love hiding in wood piles. If you store firewood, keep it away from your home’s foundation.

The Role of Landscaping in Centipede Prevention

Can Landscaping or Outdoor Conditions Near a Home Influence Centipede Infestations?

Absolutely. The external environment around a home can play a significant role in either inviting or deterring centipedes:

  • Clear Debris – Regularly clear leaves, grass clippings, and other debris from around your home, as these can provide hiding places for centipedes.
  • Maintain Lawns – Mow the lawn regularly and avoid overwatering to reduce moist areas that attract centipedes.
  • Plant Choices – Some plants can repel insects and, indirectly, the centipedes that prey on them. Lavender, for instance, is known to deter many pests.

Household Products or Chemicals That Can Deter Centipedes

  • Diatomaceous Earth – This natural powder can be spread around potential entry points. It causes dehydration in centipedes and other crawling pests, effectively deterring them.
  • Natural Repellents – Essential oils, such as tea tree, peppermint, or eucalyptus, can deter centipedes when sprayed in areas where they’re commonly found.
  • Pesticides – There are specific commercial pesticides designed to repel or kill centipedes. However, these should be used cautiously, especially if there are children or pets in the home.

How Do Household Habits or Routines Influence the Likelihood of Centipedes Moving In?

Our daily habits can inadvertently create inviting conditions for centipedes:

  • House Cleaning – Regular cleaning, especially in dark and damp areas like basements, can deter centipedes by removing their hiding places.
  • Storage Practices – Avoid storing items in cardboard boxes directly on the basement floor, as these can attract moisture and, in turn, centipedes.
  • Indoor Plant Care – Overwatering plants can increase indoor humidity, making the environment more appealing to centipedes. Ensure plants are adequately drained and trays do not retain excess water.
  • Regular Inspections – Periodically inspecting less-frequented areas of the home can help in early detection and prevention of a potential centipede problem.

By taking a proactive approach and integrating preventive habits into daily routines, homeowners can create an environment that is less attractive to centipedes, ensuring these critters remain where they belong—outside.


Centipedes, often misunderstood and surprisingly beneficial, can be a cause for both intrigue and concern in homes. Drawn indoors by dampness and prey, they pose minimal risk to homeowners but can be a nuisance. Addressing misconceptions, it’s crucial to understand that not all centipedes are harmful and they aren’t attracted to unclean environments. To maintain a centipede-free home, focus on moisture control, home sealing, and mindful landscaping. With informed practices, homeowners can coexist with these creatures, appreciating their role in the ecosystem while ensuring they remain outside our living spaces.
