Let’s dive into the fascinating world of centipedes, those multi-legged creatures that often get a bad rap. Did you know they’re actually beneficial to our ecosystem? These little guys are nature’s pest control, helping keep populations of roaches, silverfish, flies, and even termites in check.
Sure, centipedes have venom, but don’t let that scare you off. They’re not out to get us humans and rarely bite. Even if they did, their venom isn’t usually harmful unless you happen to be allergic.
Now, let’s talk about the house centipede (Scutigera coleoptrata). This is the only type that likes to set up shop indoors. While they’re harmless, I’ll admit their appearance can be a bit startling. All those legs and segments might make you jump if you’re not expecting to see them!
But here’s the thing – if you’re spotting these critters regularly, it might be time to play detective. Their presence could be a sign that your home has some excess moisture or even an insect problem that needs addressing.
Ready to learn more about your multi-legged housemates? Let’s explore everything you need to know about house centipedes.
Introducing House Centipede
Meet the house centipede, or Scutigera coleoptrata, a frequent guest in many U.S. homes. Often nicknamed “hundred-leggers” for their numerous legs, these critters typically stretch between one to two inches long, excluding their legs.
Sporting 15 body segments, each segment is paired with long, slender legs, which is fewer than some of their kin but in line with the odd-numbered leg pair rule among centipedes.
Though their swift movement and lengthy appendages might startle some, house centipedes are benign. They play a beneficial role indoors by hunting smaller arthropods, like pest insects. If you’re spotting a lot of them, it might be a sign of another pest problem in your home.
Let’s break down their classification a bit:
- Common Name: House Centipede
- Species: Scutigera coleoptrata
- Family: Scutigeridae
- Order: Scutigeromorpha
- Class: Chilopoda
House centipedes bear a somewhat menacing look with their dark brown or yellow bodies, adorned with darker markings and three distinct, dark lines running from head to tail. They sport a pair of bushy antennae and can have varied eye arrangements—from complex, multi-lensed eyes to simple ones or none at all.
Interestingly, they have specialized front legs, called forcipules, situated just below their mouths. These are adapted to deliver a venomous punch to subdue prey or deter predators, effectively acting as both spear and shield. The trailing pair of legs is exceptionally long, mimicking their antennae, which confuses prey about which end is which.
Adult females flaunt the most dramatic legwear; their last pair of legs can be nearly twice as long as their body, giving them an exaggerated length of up to four inches when you account for legs and antennae. The striking banded pattern on their legs and a primarily yellow body with longitudinal stripes round off their distinctive appearance.

Lifecycle of House Centipedes
These unique creatures have a three-stage life cycle: egg, larva, and adult. They’re outdoor winter dwellers, but come summer, female centipedes get busy. They’ll burrow into the soil and lay up to 35 eggs over a few days.
Growing up isn’t simple for these little guys. They go through six larval stages, each ending with a molt. Then, they’ve got four more post-larval stages before they’re fully grown. Talk about a long childhood! But it’s worth the wait – female centipedes can live for years and have up to 150 offspring.
During the day, these shy creatures hide in dark, damp spots around your home. But at night, they’re on the prowl for food. When they first hatch, baby centipedes only have four pairs of legs. But with each molt, they gain more. It’s like a leg lottery – 5, 7, 9, 11, 13, and finally 15 pairs when they’re adults.
House centipedes are the marathon runners of the insect world. While many bugs live for just one season, these guys can stick around for up to seven years, though most make it to about three. That’s a lot of time for munching on other creepy crawlies like silverfish, carpet beetle larvae, and cockroaches.
Here’s a fun fact: if you’re seeing a lot of centipedes, it might mean you’ve got a buffet of other bugs in your house. So while they might give you the heebie-jeebies, these leggy lodgers could actually be telling you about a bigger pest problem!

House Centipede Hideaways
Ever wondered where those speedy, many-legged creatures like to hang out? House centipedes have a knack for finding cozy, damp spots in and around your home. Let’s explore their favorite hideaways!
Inside your house, these critters love cool, moist areas. You’ll often spot them in basements, tucked away in closets, or scurrying across bathroom floors. They’re also fans of potted plants and unexcavated spaces beneath your home. If you’ve got firewood stored inside, check under the bark – it’s prime centipede real estate!
But how do they sneak in? These crafty insects have a few tricks up their sleeves (or should we say, legs?). They can squeeze through tiny cracks in concrete slabs, wriggle into gaps in cement block walls, or even pop up through floor drains that lack water traps. And if you’ve got cardboard boxes sitting on a concrete floor, you might have some unexpected roommates!
Outdoors, house centipedes feel right at home under logs, rocks, and fallen tree bark. They’re night owls, preferring to hide during the day and come out after dark to hunt.
While you might freak out when you spot one on your bedroom wall or trapped in the bathtub, remember – these aren’t their usual hangouts. They much prefer those damp, dark corners of your home.
One thing you don’t need to worry about? Centipedes crawling up through your pipes. Despite popular belief, they’re not fans of drain surfing.
Are House Centipedes Dangerous?
House centipedes might give some people the creeps with their appearance, but they’re actually harmless to humans and pets. In fact, they’re beneficial as they hunt down household pests like cockroaches, silverfish, and even bed bugs. These speedy critters use their numerous long legs to snatch up prey swiftly, ensuring pests have no chance of escape.
It’s quite rare for a house centipede to bite humans or animals. Their jaws aren’t very strong, so on the off chance you do get bitten, it’s likely to only cause minor swelling. They do have venomous fangs, which they use to kill their prey, but the venom isn’t harmful to humans.
You might experience a slight reaction similar to a bee sting if bitten, but such instances are extremely uncommon and usually happen only if the centipede is provoked.
Visually, house centipedes sport a yellowish to dark brown hue and can grow up to an inch and a half with 15 pairs of legs. This enables them to move quickly, up to a foot per second. While they may look daunting, they don’t pose a threat to your clothes or furniture like moths, nor do they damage your pantry goods like ants.
Unlike their plant-eating millipede relatives, house centipedes are carnivores that focus on other insects. Although they use their jaws to deliver venom to their prey, it’s highly unlikely for them to bite a human unless mishandled. If a bite does happen, it typically feels like a mild bee sting.

Are House Centipedes Actually Helpful?
Believe it or not, house centipedes are actually the good guys in your home! From an expert’s perspective, these creepy crawlies do more good than harm by feasting on other unwanted pests.
Think of them as your personal, eco-friendly pest control service. They have a knack for hunting down insects like spiders, ants, cockroaches, and silverfish—all of which you’d probably rather not have around.
These leggy arthropods are night owls, doing most of their pest patrol during the darker hours. This means they’re out of sight while you’re asleep, quietly handling nuisances by sneaking into the nooks and crannies where pests love to hide.
What’s more, the average female house centipede lays dozens of eggs, multiplying their helpful impact without you even noticing. While the thought of many centipedes might make you shudder, rest easy knowing they’re likely hidden and working hard to keep your space bug-free.
So, the next time you spot one, you might just want to let it scurry on its pest-controlling way!

Why Are There House Centipedes in My Home?
Ever wonder why you’re spotting house centipedes scurrying around your place? These critters are mostly active at night, making it hard to catch them in the act. If you start seeing them regularly, it could mean they’re not alone—other pests might be lurking about, serving as a buffet for these many-legged invaders.
Your home could be more inviting to house centipedes if you’ve got other pests like cockroaches, termites, or spiders. These bugs are like a call to dinner for centipedes, especially in quiet, dark, and damp spots like your basement.
These sneaky guests find their way in through the smallest cracks and crevices in search of moisture. They’d rather be outside under logs or in leafy debris where it’s moist, but if they do slip inside, they head straight for similarly damp places like musty closets or shadowy corners.
The warmth and security of your heated home can also draw them in, particularly during the bitter cold of winter or dry spells when outdoor conditions are tough. They feast on various pests—think cockroaches, silverfish, and moths.
While it might seem beneficial that they’re handling other pests, their presence is a red flag that you might have a larger pest problem to tackle.
Here’s what attracts house centipedes to your home:
- Moisture: These pests thrive in damp environments. Keep an eye on moisture around your home—fix leaky spigots, ensure gutters are unblocked and functioning properly, and manage soil dampness by adjusting your landscaping to keep the area dry.
- Food: Centipedes are on the hunt for food, which often leads them close to your home. They dine on insects that lurk around your yard, drawn by moisture and plants. Keeping your yard clean of debris and excess vegetation can cut down on their food sources.
- Shelter: Clutter and debris around your house can offer centipedes and other pests shelter. Clear out any piles of wood, leaves, or unused items that could become pest havens.
To deter these unwanted guests, start with a thorough inspection of your home’s exterior. Seal any cracks and gaps, check the integrity of screens on windows and doors, and remember—just a tiny opening is all a centipede needs to make your home theirs.
Keeping your yard tidy and your home dry and sealed are your best defenses against these creepy crawlers.

How to Handle a House Centipede
If you spot a house centipede scurrying across your floor, don’t panic! These critters might give you the heebie-jeebies, but they’re actually nature’s pest control agents. A house centipede’s presence often points to a bigger bug problem in your home. They thrive where they can feast—meaning if you’ve got them, you likely have other unwelcome insects too.
To manage a centipede population, first focus on cutting off their food supply. Use sticky traps to find out what other pests are lurking around, then eliminate these insects with your preferred pesticide, whether it’s a natural solution or a chemical one.
Centipedes are also suckers for moisture, so check for any leaks and consider a dehumidifier to dry out damp areas like basements, which could be their perfect hideout.
Encountering these many-legged creatures can be startling, but remember, they’re more scared of you than you are of them and they’re not harmful to humans.
Instead of crushing them (which can release an unpleasant smell), gently trap and release them outside where they can continue keeping other pests in check. Just cover them with a cup, slide some paper underneath, and set them free.
Managing centipedes effectively involves more than just eviction. Seal up cracks in walls and around the foundation, put screens over drains and sump pumps, and reduce humidity in your home by using dehumidifiers and improving soil grading around your house to keep moisture away from the foundation.
Ultimately, house centipedes don’t need to be feared or exterminated. They help control more annoying pests. If the sight of them is too much, focusing on reducing other pests and drying out your home will naturally reduce their numbers without resorting to pesticides, which are often ineffective against them due to their high-stepping gait.
Keep your spaces dry and clean, especially basements and dark corners, to make them less inviting to centipedes.

Keeping House Centipedes at Bay: Practical Tips for a Pest-Free Home
Want to keep those creepy-crawly house centipedes out of your space? It’s easier than you might think! First things first, seal off their entry points. Take a good look around your home’s exterior—check the walls, foundation, and any gaps around windows and doors. Using caulk to fill these gaps can significantly reduce their chances of sneaking in.
Moisture is a big draw for these pests, so it’s crucial to keep your home dry. A dehumidifier works wonders in pulling excess moisture from the air.
Don’t forget to run those exhaust fans in your bathrooms and attics, especially after a steamy shower or during humid weather, to keep the dampness down. Tackling any leaks or plumbing issues also helps in making your home less inviting to centipedes.
Lastly, centipedes thrive in cluttered, dark environments. By keeping your living spaces neat and tidy, you reduce their hiding spots. Make it a routine to vacuum and clean regularly, focusing on drains and pipes to ensure they’re clear of organic debris.
Addressing any bug infestations swiftly will also cut down on their food sources, making your home less appealing to these unwelcome guests.
By combining these measures, you can create a less hospitable environment for house centipedes and enjoy a pest-free home.
