Centipedes are one of the most common crawling creatures people see inside their homes. For many, just seeing one is enough to cause fear or panic. They move fast, have many legs, and often appear suddenly in dark corners. But an important question remains: Are house centipedes dangerous to humans?
In this blog post, we will explain everything you need to know about centipedes in very simple terms. We will talk about different types of centipedes, which ones are dangerous, which ones are harmless, and why they even enter our homes. We will also answer an important question for pet owners: Are house centipedes dangerous to cats?
By the end of this article, you will no longer be afraid of these creepy crawlers.
What Are Centipedes?
Centipedes are small crawling animals with long, segmented bodies and many legs. Each part of their body has one pair of legs, which makes them move very fast. Because of their appearance, many people think they are insects, but they are actually part of a larger group called arthropods.
Scientists often group centipedes and millipedes together because they look similar. However, centipedes are hunters, while millipedes usually eat plants and dead matter. Centipedes are built for speed and catching prey.
There are many different species of centipedes all around the world. Some live in forests, grassy areas, and wild places. Others live inside houses, bathrooms, basements, and kitchens.
Different Types of Centipedes
Not all centipedes are the same. Some species are harmless, while others can be dangerous. The danger level usually depends on where they live and their size.
Forest and Wild Centipedes
Centipedes that live in forests or grassy areas are often larger and more aggressive. These types usually have orange, dark red, or brown colors. They can grow very big, with some special species reaching lengths of 24 to 30 inches.
Because of their size and strength, large wild centipedes can hunt small animals. There have been cases where they prey on lizards, frogs, and even fully grown rats. These species have venom that they use to paralyze their prey.
These are the centipedes that people should avoid touching, especially when outdoors.
House Centipedes
House centipedes are very different from their wild relatives. They are usually smaller, thinner, and lighter in color. They are often gray, yellowish, or light brown.
House centipedes prefer dark, damp places like bathrooms, sinks, basements, and storage areas. They hide during the day and come out at night to look for food.
Are House Centipedes Dangerous to Humans?
The simple and clear answer is: No.
House centipedes are not dangerous to humans. They do not carry deadly poison, and they are not aggressive toward people. If you accidentally touch one, you will not be harmed.
In very rare cases, a house centipede may bite if it feels trapped. Even then, the bite is usually no worse than a small bee sting. Most people never experience a bite at all.
House centipedes do not spread diseases. They do not contaminate food. They do not damage furniture or clothes.
Their scary appearance is the main reason people fear them, not their actual behavior.
Why Do Centipedes Enter Houses?
Centipedes enter houses for one main reason: food.
House centipedes feed on other small insects. This includes ants, termites, cockroaches, spiders, and other bugs. If your house has many insects, centipedes will follow.
They are attracted to:
- Unsealed food sources
- Crumbs and food waste
- Moist and damp areas
- Cracks, holes, and wall gaps
Ants are one of their favorite food sources. Ants usually invade houses because of exposed food or sugary spills. Termites, on the other hand, are attracted to wooden structures.
If insects can enter your house, centipedes can enter too.
Are Centipedes Actually Helpful?
Yes, they are.
Even though they look scary, house centipedes are actually helpful creatures. They act like natural pest control inside your home.
They hunt and eat:
- Ants
- Termites
- Bed bugs
- Spiders
- Small cockroaches
Because of this, many experts consider house centipedes as beneficial. They help reduce the population of harmful insects without using chemicals.
They are not pests like bed bugs or termites. They do not destroy homes or cause infestations.
How to Get Rid of Centipedes Naturally
If you really want to get rid of centipedes, killing them is not the best solution. The best way is to remove what attracts them in the first place.
Simple Steps to Keep Centipedes Away
- Clean your house regularly
- Seal all food containers properly
- Fix wall cracks and small holes
- Reduce moisture in bathrooms and basements
- Get rid of ants and other insects
Once their food source is gone, centipedes will leave on their own. They are not trying to invade your home. They are just trying to survive.
Please remember that centipedes mean no harm. They simply found food inside your house by coincidence.
Cats vs Centipedes
Are House Centipedes Dangerous to Cats?
If you own a cat, you may have seen it chasing a centipede around the house. Cats are naturally curious and love to hunt moving objects.
The good news is that house centipedes are not dangerous to cats. They do not have deadly venom that can harm household pets.
Most of the time, the cat wins the encounter. Even if a cat bites or plays with a house centipede, there is usually no danger.
The only risk comes from large wild centipedes found outdoors. If a cat plays in grassy fields or forests, it may encounter a dangerous species. That is why it is best to monitor pets when they are outside.
Final Thoughts
Centipedes may look frightening, but most of them are harmless. House centipedes do not pose a danger to humans or cats. They do not carry diseases and do not attack people.
In fact, they help control other insect populations inside your home. Instead of killing them, focus on cleaning, sealing food, and fixing entry points.
Understanding these creatures helps remove fear and promotes a safer, cleaner home.

It's scary to have and see them around. I'll kill them when I see them around.
ReplyDeleteI've been bitten and it hurts like a scopion bite.
Delete...scorpions don't bite, they sting...
DeleteIt says 24-30 ft im pretty sure you meant inches otherwise I'd be scared to ever go outside :P
ReplyDeleteMutant ninja anaconda centipedes, maybe???
DeleteOh sorry, you are right it should be in "inches". Thanks for the correction.
ReplyDeleteI'm not sure what the oher anonymous was reading, but I scrolled back up and your article does say 24 - 30 inches...not feet.
Delete"Please don’t kill them as they meant no harm in trying to invade your house", Are you kidding me?
ReplyDeleteI will burn them with a flame thrower. Any insect in the house is an enemy to me! sigh.
Yes but they eat bedbugs and cockroaches.
DeleteThey are being attracted into your house because of the source of food that they can eat. No matter how much you burn everyone of them, they will still keep coming.
ReplyDeleteDo they lay eggs or are they just made out from dust and dirt?
ReplyDeleteYes, they do lay eggs.
ReplyDeleteI hope he wasn't serious about that question... I saw one for the first time in my bathroom area...Is there anything I can do to prevent them from coming in my home? I live in an apartment, so am I trying to win a losing battle? Please help me...
ReplyDeleteClean your room, they are probably attracted to other insects around your room such as ants, cockroaches and other similar pests.
ReplyDeleteThey're everywhere! I spray them with generic Kroger lemon cleaner to slow them down then quickly smash them with a shoe. I hate to kill God's creatures, but house centipedes are really scary. All those legs! They love wet and woodsy Indiana, and when it's cold outside they're inside tormenting me. By the way, centipedes are poisonous. But pesticides are carcinogenic. Boric acid?
ReplyDeleteCan you imagine the females trying to shave their legs? Bahahahaha
DeleteHa ha good one
DeleteThose with black colored bodies with red legs are the once that are very dangerous.
ReplyDeleteCentipedes are not dangerous and cannot kill you, this guy has no idea what he is talking about
DeleteActually, I think you meant centimeters...
ReplyDeleteIn response to: "It says 24-30 ft I'm pretty sure you meant inches otherwise I'd be scared to ever go outside"
Is it possible that it enters into human ears?
ReplyDeleteYes, it is possible especially those small once.
ReplyDeleteWtf, they can enter into your ears. Now, I will kill them all every time that I see one.
DeleteYou better hire a Pest Control Service.
DeleteIs it okay to keep the black house centipedes as little pets?
ReplyDeleteYes. In fact, they are considered as exotic pets.
DeleteWhat do you mean by "aggressive"? They don't like being handled? Btw, I love house centipedes.
ReplyDeleteSome people actually find them aggressive. Anyway, I am curious to know about what makes you love them?
DeleteOmg they are disgusting looking. I have such a bad phobia of these things! I usually kill them with bleach though and it scares me when they move. It's just so unnatural to me lol.
ReplyDeleteWill they go out of their way to go into your ear and is there any way to prevent it
ReplyDeleteIf it got inside your ear, the method to remove it is called "flushing". Anyway, it's best to consult your doctor if you do not know what you're doing. And to prevent the insect from going inside your ear, put cotton or foam ear plugs.
DeleteCentipedes scare the hell outta me.....I don't even know why they exist WTH re they lookin for in our body....ewww they re so disgustin nd frightening I practically get petrified 😬😠😠ðŸ˜
ReplyDeleteTheir existence is actually very important because they "Balance the Ecosystem".
DeleteI was turning off the light to the room when I noticed one on the ceiling above me. I instantly thought of a story I heard about super poisonous centipedes and I freaked out and ran into the other room. Thank you sooo~ much, I've finally quit feeling like their crawling on my.
ReplyDeleteNo they won't go in your ears goofballs.
ReplyDeleteWhat happens if it enters your ear
ReplyDeleteAn ear Specialist will have to perform a method called "Flashing" to get the insect removed.
DeleteI recently moved and have killed about 4 of these cretens. Each one slightly more gross than the other. I have a cat and although its because of her that I'm altered to centipedes and all other cretens, but it sucks that in her natural instinct to want to chase, torment and eventually kill these cretens, he has a bad habit of bringing them on my bed. Just had to jump out of my bed because she brought a centipede in it. It was the fastest I ever stripped off clothes and all beddings to find and kill the centipede. Now I'm freaked out and can't go back to sleep. P.S. I'm locking her out of the bedroom from tonight
ReplyDeleteThat's a terrible experience. Anyway, most cat will eat it right away but in your case, your cat is probably curious if the creature he caught is edible or not. The reason why he took it on your bed to ask for your confirmation.
DeleteOh dam I see one an it's gone seconds later be the time I get a broom an I have no ants or especially no roaches. In my house à don't pay bills it's dead!! My cat earns her food! Now im on look out on my bed!!
ReplyDeleteIt's not just ants or roaches, they also prey on other sorts of insects like termites which can hardly be noticed lurking in the interior parts of your house.
DeleteWhat happens if it does enter your ear exactly !!! And what if its also poisonous then what ......................!!!!!
ReplyDeleteThere is a proper medical procedure on how to remove the insect from your ear. Best thing to do is to take it to a doctor to perform the operation.
Deletedo u need to apply an ointment after a centipede bit or it ok to leave it that because it painful
ReplyDeleteIts all written above,and also they can go into your ears. I know this because once a centipede was crawling on my neck and i just in time before it could rmter my ear. And if it enters youur ear ever, rush to your doctor.
ReplyDeleteThat centipede with redish legs and black body bit my mom's toe. Should she see a doctor?
ReplyDeleteIf you see one in your room after you wake up, and try to kill it but it gets away. What should you do? P.S. It was gray.
ReplyDeleteThe best method is to clean your house. Take note, centipedes prey on other insects. Most of these insects are present around your house due to access to foods. One good example are ants.
DeleteIf you found it in your room and you don't kill it your just scared as heck, Is it ok to sleep in your room? It was a grey one.
ReplyDeleteJust turn the lights ON when you go to sleep. Centipedes are afraid to go out on a bright environment.
DeleteYes, they can go in your ear. I guy from Arkansas woke up with his ear hurting and pulled out a 4-inch centipede. It's shown on youtube and yes, it is real. He went to the hospital.
ReplyDeletepeace
Ummm a centipede bite landed me in the ER last year. It feels a little worse than a bee sting, but then my whole arm went numb. I was just cleaning out a cabinet, and it bit me on the finger. It was only about an inch long, but man... It was terrible. So they are poisonous, but definitely not deadly. I've only seen 2 or 3 more, but I killed them instantly.
ReplyDeletePeople are afraid of things they don't understand this type of bond is very intelligent enough to avoid humans you see them incoming houses because they have other bugs like roaches,spiders, ants, temites, even bed bugs. If you dont wanna see them clean your house and they wont comeback
ReplyDeleteYes there needed but one went into my indoor shoe it starteld me and I killed i saw a second one mer minutes later.
ReplyDeleteI know their harmless and I have seen them for years but recently they have become more active.
ReplyDeleteJust seen one tried to capture or end it in process. Then my laundry basket falls riitte on it. Smh.
ReplyDeleteI just woke up I was on my cell phone in the dark using the light from my cell phone I saw one crawling on my pillow toward my ear and I jumped up to find it and it crawled away down the side of the mattress. I'm going to try looking for it cause I'm scared to go back to bed
ReplyDeleteI just encountered a centipede in the bathroom,I can't take a nice warm bath with the bastard still sticking in the wall. I tried washing it off the wall then it immediately fell.I thought it would work that it may possibly drown but then the little bitch is still alive then he was hella fast wiggling through the floor.And now I can't kill it cuz he hid behind the toilet.I would burn down the whole bathroom even if you say it's harmless. I CAN'THE STAND THEM, I hate bugs.
ReplyDeletetheres a centipede in my room its maybe 7 cm and its not afraid of light tiny legs looks brown or copperish
ReplyDeleteI agree I will kill any bug/insect whatever I just can't share inside my house w them. I had rented a house that was infested w them and I had never seen One before until I moved into this house, I had no idea what it was first time I saw one and it was big I almost had heart faliure! I think they r so awful and discussting w all there big creepy legs. They were everywhere like a ufo stopped above the house and dropped them off I was discussted when I first saw it then kept seeing them even at night run across the bed and I complained few months before my land lord called an exterminator but by then I was so grossed out I moved out I took non of my furniture nothing I had stored in basement I was too afraid they would be in there. I can't stand them that place tromotized me an it was an nice clean house I never thought it would be such a nightmare.
ReplyDeleteI love centipedes.In my houses there are centipedes present in every room and each one is of different colour and I don't think they are house centipedes because they are big enough and colourful like red,purple,black,blue,yellow,orange etc.I have been living with them from 25 years of my life and I seriously like them and love them and I have never killed them even if they come so close to me.So therefore never kill a centipede,spider ,cockroach or ants because they also have all the right to live there beautiful and happy life so love them please don't kill them as God made them just like he made us.thankyou.
ReplyDelete😣 ewwww!!! I kill them when i see them. I live in a basement apartment. Had never seen one in person before I moved here. So grossed out! 😧
ReplyDeleteI woke up this morning and found one in my bathroom, I came here to figure out how poisonous now I know thanks
ReplyDeleteWhat happens if it's body get split in half I smacked one few minutes ago using a slipper but both half are still wiggling.
ReplyDeletecentipedes are repulsive and dangerous all of them, kill them the moment you see them when in bathroom pour some toilet cleaner on them, toilet cleaners have hcl acid in them, which kills these creatures in seconds, & so you dont have to jump up & down to squish them under your feet
ReplyDeleteOmg! How can someone live with monster for 25yrs. That creature is disguisting. I can't stand it.
ReplyDeleteI never knew this night would come! I am not really an early sleeper so while watching the TV I saw something crawling so swiftly toward my where my TV was. I summoned up courage,picked up a broom but twas long and fast gone. Few minutes later it crawled swiftly again right under my bed and that's when I saw it- a centipede!!! I can't find it under my bed now. I hate centipedes;i hate it's name and what it looks like! Now I'm caught between sleep and centipede! I don't deserve this! I hate creepy,crawling insects or anything that looks like it. They disgust me. Nat Geo wild says they dangerous! Why me,God?!!!
ReplyDeletecan a centipede enters your brain through ear?
ReplyDeleteit greeted my finger what i thought at first was just wind while browsing the net and i freaked out..because of shyness it also ran away..at quick glance it was Scolopendra gigantea about ~10inches long as i watch it creep back into wooden furniture..dem it is a majestic creature but hans get the flammenwerfer!!
ReplyDeleteI was using the toilet without knowing there is a centipede in it. So close to my ass. Oh my God. When I got up later to wash my hands and stuffs, that is when I saw it! A frickin centipede which was only a centimeter away from my ass. It is so ugly and scary. Oh my God, what if it went into my ahole?
ReplyDeleteI saw one in my sink. I just moved into an apartment that was in renovation few days ago. Went to the sink just rinse a glass then I saw this creepy crawling creature with long legs everywhere. I screamed and boil water to flush it there. But ever since that day I cannot sleep with lights off, just incase.
ReplyDeleteI just leave them alone. Sure, they're creepy, but, in small numbers, they're really more useful than annoying (and they actually have cute little faces). If I find them in a place I don't want them, I catch them and move them to the unfinished part of my basement and usually never see the same one again. I do the same for spiders, unless it's something like a brown recluse (I found one once at work, unable to escape an empty plastic bucket) or a black widow (I have yet to find one), in which case I take it to the nearby woods to fend for itself. But house centipedes? I'd much rather have them than ants. (Ick. I loathe ants.)
