Why Are They Inside Your Home?
House centipedes usually enter homes for two simple reasons:
1. They Are Looking for Food
Their presence often indicates that other insects are already living in your home. If there’s a steady supply of prey, centipedes are more likely to stay.
2. They Prefer Moist Environments
Bathrooms, basements, laundry rooms, garages, crawl spaces, and damp storage areas provide the humidity they need to survive.
What Should You Do If You See One?
If you don’t want house centipedes indoors, there’s no need to kill them.
Instead, you can:
- Place a glass or container over the centipede.
- Slide a stiff piece of paper underneath.
- Carry it outside and release it away from your home.
This removes the centipede while allowing it to continue controlling insect populations outdoors.
How to Prevent House Centipedes Naturally
If you regularly see house centipedes, the goal shouldn’t be eliminating the centipedes—it should be eliminating what attracts them.
You can reduce their numbers by:
- Fixing leaking pipes and faucets.
- Using a dehumidifier in damp rooms.
- Sealing cracks around doors, windows, and foundations.
- Keeping storage areas clean and clutter-free.
- Controlling ants, cockroaches, silverfish, and other insects.
- Vacuuming regularly to remove insects and eggs.
Once their food supply disappears, house centipedes usually move elsewhere.
Common Myths
Myth: They damage furniture or clothing.
Fact: House centipedes do not eat wood, fabric, paper, or food.
Myth: They’re a sign your house is dirty.
Fact: Even clean homes can attract house centipedes if moisture and insects are present.
Myth: They’re poisonous to people.
Fact: They possess venom for catching tiny insects, but they rarely bite humans and are not considered medically dangerous for most people.
The Bottom Line
While their appearance may be unsettling, house centipedes are more friend than foe. They quietly patrol your home, feeding on many of the pests homeowners spend money trying to eliminate.
If you spot one occasionally, it’s often a sign that nature’s own pest control is already at work. However, if you notice large numbers of house centipedes, it may indicate an underlying insect or moisture problem that deserves attention.
Sometimes, the creature that looks the scariest is actually one of the most helpful visitors your home can have.
