How to Prevent Centipedes from Entering Your Home

Centipedes, despite their harmless nature to homes, have become a growing concern for many homeowners. Their alien appearance, coupled with their rapid movement, can be startling, leading many to seek ways to prevent their unwanted entry. While their presence might be alarming, it’s crucial to remember that centipedes play a vital role in the ecosystem, preying on other household pests like ants and spiders. Therefore, when considering prevention methods, it’s essential to strike a balance. Ensuring our homes remain centipede-free shouldn’t come at the expense of causing broader environmental harm or disrupting the delicate balance of our local ecosystems.

Understanding the Centipede

Centipedes are fascinating creatures, and to effectively prevent them from entering our homes, we must first understand what lures them inside.

What Attracts Centipedes to a Home?

A primary factor that attracts centipedes to a house is moisture. Centipedes thrive in damp environments, and they often venture into homes in search of these conditions. 

Role of Moisture Levels in Attracting Centipedes

Homes with high humidity levels, unchecked water leaks, or standing water provide the perfect breeding ground for centipedes. Areas like basements, bathrooms, and crawlspaces, which often retain more moisture than other parts of the home, can be particularly enticing to these arthropods. To reduce the appeal of your home to centipedes, it’s advisable to maintain optimal humidity levels, quickly address any leaks or water seepage, and ensure proper ventilation, especially in areas prone to dampness.

Other Pests that Centipedes Prey Upon

Beyond the allure of moisture, centipedes are also attracted to homes abundant in food sources. These arthropods are carnivorous and feed on a variety of smaller household pests. Common prey for centipedes includes ants, spiders, bedbugs, silverfish, and cockroaches. By reducing the populations of these pests in your home, you indirectly make your living space less inviting to centipedes. Regularly cleaning, avoiding leaving food out, and addressing other pest infestations promptly can reduce the likelihood of a centipede making your home its hunting ground.

The Life Cycle of a Centipede and Their Most Active Times

Centipedes go through three primary life stages: egg, nymph, and adult. Females usually lay their eggs in damp soil, producing anywhere from 15 to 60 eggs at a time. Once hatched, the nymphs closely resemble smaller versions of adult centipedes but have fewer leg pairs. As they grow, they undergo several molts, acquiring additional pairs of legs with each stage until they reach maturity. Depending on the species and environmental conditions, a centipede’s life span can range from 1 to 6 years. Centipedes are nocturnal creatures, meaning they’re most active during the night. This is why nighttime is when homeowners are most likely to encounter these arthropods scurrying across a floor or wall.

Differences Between Centipedes and Millipedes, and Their Significance

While they might appear similar at first glance, centipedes and millipedes are distinct creatures with different behaviors and habitats. Centipedes are generally flat, with long, segmented bodies and one pair of legs per segment. They are carnivorous, preying on other small pests. Millipedes, on the other hand, have a more rounded body with two pairs of legs per body segment and are predominantly detritivores, feeding on decaying organic material. When threatened, centipedes are more likely to flee, while millipedes tend to coil up in defense. Understanding these differences is crucial as it informs the approach one should take in prevention and management. For instance, reducing organic debris might deter millipedes but won’t have the same effect on centipedes.

Potential Dangers Posed by Centipedes to Humans and Pets

While centipedes can appear menacing, they’re generally not harmful to humans or pets. However, some larger species possess venomous jaws (forcipules) which they use to paralyze their prey. If threatened or accidentally stepped on, a centipede might bite, causing localized pain, redness, and swelling, similar to a bee sting. While such bites are usually not dangerous, they can cause discomfort. Individuals who are allergic might have more severe reactions and should seek medical attention. Pets, especially curious cats or dogs, might try to play with or eat a centipede, which could result in a bite. It’s always advisable to keep an eye on pets and keep them away from any centipedes you might find in your home.

Entry Points and Habitual Spaces

To prevent centipedes from making an unwelcome appearance, homeowners must understand their entry methods and preferred habitats.

How Do Centipedes Typically Find Their Way into Homes?

Centipedes are skilled infiltrators, exploiting even the smallest of gaps to gain access to the cozy interiors of our homes. 

Specific Areas or Rooms in a Home More Prone to Centipede Entry

Basements, crawlspaces, and ground-level rooms are the most common points of entry due to their proximity to the outdoors and often damp conditions. Bathrooms and kitchens, with their plumbing and occasional leaks, can also attract these creatures. Any area of the home with high humidity or moisture is a potential hotspot. Gaps beneath doors, cracks in the foundation, or improperly sealed windows and vents can serve as gateways for these agile arthropods.

Importance of Regular Inspection of the Home for Centipede Entry Points

Regularly inspecting and maintaining the home’s structural integrity is vital in keeping centipedes at bay. Seal any noticeable cracks, gaps, or holes in walls, floors, and foundations. Weatherstripping can also be installed around windows and doors to ensure a tighter seal. Ensuring that crawlspaces are properly ventilated and free from excess moisture can further deter these pests.

The Connection Between Outdoor Lights and Centipede Attraction

While centipedes are not directly attracted to light, the insects that they prey upon are. Outdoor lighting can draw in a myriad of small insects, which in turn can become a buffet for centipedes. Homeowners might inadvertently create a thriving ecosystem right outside their doorsteps. It’s advisable to either limit outdoor lighting during night hours or to opt for yellow “bug lights” which are less attractive to insects.

Role of Clutter, Debris, Mulch, and Landscaping in Centipede Infestations

Centipedes seek shelter in spaces that mimic their natural habitat. Piles of leaves, logs, stones, or dense vegetation close to the home can offer them refuge. Inside the house, cluttered areas provide them with ample hiding spots. Mulch, while beneficial for plants, can create a moist environment conducive for centipedes if placed too close to a home’s foundation. It’s recommended to keep a buffer zone of at least a foot between any mulch and your home’s foundation. Regularly clearing debris and maintaining a tidy yard can drastically reduce the likelihood of a centipede invasion.

Natural and Commercial Preventative Measures

When it comes to deterring centipedes, homeowners have an array of options, ranging from nature-inspired solutions to commercial products. Here’s a deeper dive into some of the most effective strategies.

Natural Remedies to Deter Centipedes

Specific Plants or Herbs Known to Deter Centipedes


This aromatic plant is not only pleasing to the human nose but also acts as a natural repellent for centipedes. Planting lavender around your home’s foundation or keeping sachets of dried lavender indoors can deter these pests. A mature lavender plant can be bought at most local nurseries for around $10-$20.


Another aromatic deterrent, mint plants, can be strategically placed around the home. While they repel centipedes, it’s worth noting that mint can be invasive in gardens. To prevent it from taking over, consider planting mint in pots. A small mint plant typically costs between $3-$7.

Essential Oils Effective Against Centipedes

Eucalyptus Oil

Recognized for its strong scent, eucalyptus oil can deter centipedes when diluted with water and sprayed around potential entry points. A 4 oz. bottle of high-quality eucalyptus oil, like that from the brand NOW Foods, often sells for $10-$15.

Tea Tree Oil

Another potent essential oil, tea tree, can be used similarly to eucalyptus. Mixing a few drops with water and spraying around the home can serve as a barrier against centipedes. Brands like Aura Cacia offer tea tree oil in a 2 oz. bottle for around $10-$12.

Lemon Oil and Peppermint Oil

These can be mixed in equal proportions to create a potent centipede repellent. When sprayed in areas of concern, the mixture’s scent will deter centipedes. Popular brands like Young Living and doTERRA offer these oils, with prices varying based on size and quality, typically ranging from $15-$30 per bottle.

While using these oils, ensure good ventilation, especially if there are pets in the home. Some essential oils can be harmful or irritating to animals. It’s always recommended to do a patch test first to ensure there’s no discoloration or damage to surfaces.

Commercial Repellents: How Effective Are They?

Commercial repellents, including sprays, granules, and powders, are widely available and often claim to provide robust protection against centipedes and other pests. In general, they tend to be effective due to their strong chemical formulations. Some popular brands in the market are Ortho Home Defense, Raid, and Terro. However, the duration and extent of their effectiveness can vary based on factors like application, the concentration of the active ingredients, and the specific environment in which they are used.

Potential Health Risks Associated with Chemical Repellents

While commercial repellents are potent, there’s always a trade-off. Many of these products contain chemicals that can be harmful if ingested, inhaled, or even when they come in contact with the skin. Common ingredients like permethrin, pyrethroids, and organophosphates can cause health issues ranging from skin irritations to more severe neurological effects in high exposures. Moreover, these chemicals can also be harmful to pets, aquatic life, and beneficial insects. It’s essential to read the label, follow instructions carefully, and store these products out of reach of children and pets. Opt for brands that are transparent about their ingredients and perhaps lean towards those with more natural formulations if health concerns are paramount.

The Effectiveness of Regular House Cleaning in Preventing Infestations

Regular house cleaning is a simple yet highly effective preventative measure against centipedes and other pests. By maintaining a clean environment, you eliminate food sources for insects that centipedes prey upon, making your home less enticing for both. Sweeping, vacuuming, and mopping regularly can reduce the number of pests. Furthermore, decluttering removes potential hiding spots for centipedes. Cleaning also helps in spotting early signs of an infestation, such as droppings, eggs, or even the pests themselves, allowing for prompt action. In the long run, maintaining a clean house not only deters centipedes but also creates a healthier living environment by minimizing allergens, dust, and pathogens.

DIY Solutions and Professional Interventions

Effectively preventing centipede infestations often requires a combination of do-it-yourself methods and professional interventions. Below, we explore these strategies in detail.

Best Ways to Seal Off Entry Points and Exterior Treatment Options

Sealing off potential entry points is the first line of defense against any pest. For centipedes, focus on these measures:

  • Caulking – Invest in a high-quality caulk, like GE Silicone 2+, to seal gaps and cracks on the home’s exterior, especially around windows and doors.
  • Weather Stripping – Install or replace weather stripping around doors and windows to prevent centipedes from sneaking in. Brands like Frost King offer a variety of affordable options.
  • Door Sweeps – Attach a door sweep, such as those from M-D Building Products, to the bottom of exterior doors to close off any gaps.
  • Foundation Checks – Periodically inspect the home’s foundation for cracks or openings. Larger gaps can be filled with expanding foam, like GREAT STUFF, which costs around $5-$10 per can.

DIY Traps to Safely Catch Centipedes Inside Homes

  • Sticky Traps – While these are commonly used for spiders or cockroaches, they are equally effective for centipedes. Brands like Catchmaster offer glue boards that can be placed along walls and in corners where centipedes frequent.
  • Jar Traps – Place a tall jar or glass next to a wall at night. Centipedes might crawl into the container, but their smooth sides will prevent them from climbing out. In the morning, you can safely relocate any trapped centipedes outside.

Role of Professional Pest Control Services in Long-Term Centipede Prevention

For homeowners overwhelmed by a centipede infestation or those looking for a more hands-off, comprehensive solution, professional pest control services can be invaluable. Companies like Orkin offer specialized plans tailored to target and prevent centipedes and other pests. These professionals have access to commercial-grade repellents and equipment that can offer longer-lasting protection than store-bought products.

Additionally, they bring expertise in identifying and sealing off entry points and can provide guidance on habitat modifications to make the environment less conducive to centipede infestations. The cost of these services can vary based on the size of the property, severity of the infestation, and the specific company, but homeowners might expect to pay anywhere from $100 to $500 for an initial assessment and treatment, with follow-up visits or maintenance plans incurring additional fees.

Engaging with professionals not only offers peace of mind but also ensures that treatments are applied safely and effectively, minimizing potential risks to household members and pets.
