Centipedes are fascinating yet often misunderstood creatures that can evoke a range of reactions from curiosity to fear. These alien looking multi-legged arthropods are commonly found in homes, especially in damp, dark areas. While centipedes are generally harmless to humans and can even be beneficial by preying on other pests, their presence in your home is usually unwelcome. In this blog post, we will explore the world of centipedes, their habits, the impact they have on your home, and effective pest control solutions. By understanding these unique creatures, you can manage, prevent infestations, and how to get rid of centipedes more effectively.
What Are Centipedes?
Centipedes belong to the class Chilopoda and are elongated, multi-segmented creatures with one pair of legs per body segment. The number of legs varies depending on the species but can range from 15 to 177 pairs. Despite their name, which means “hundred legs,” no centipede actually has 100 legs.
Physical Characteristics of Centipedes:
- Body: Centipedes have a flattened, segmented body.
- Legs: They possess one pair of legs per body segment, with the first pair modified into venomous claws called forcipules.
- Color: Their color can vary, but many are brown, reddish-orange, or yellow.
Behavior and Habitat of Centipedes:
Centipedes are nocturnal predators, feeding on insects, spiders, and other small arthropods. They prefer damp, dark environments and are commonly found in basements, bathrooms, and other areas with high moisture levels. Outdoors, they live under rocks, logs, and leaf litter.
Centipede Life Cycle
| Stage | Description | Duration |
|---|---|---|
| Egg | Laid in moist soil | Weeks |
| Juvenile | Fewer leg pairs | Months |
| Adult | Full leg count | 1–6 years lifespan |
The Impact of Centipedes on Your Home
While centipedes are beneficial in controlling other pest populations, their presence can still cause concern for homeowners. Here are some reasons why you’ll want to manage centipede infestations:
- Nuisance: The sight of centipedes scurrying across the floor can be unsettling and may cause alarm, especially if they are found in large numbers.
- Bites: Although centipede bites are rare and typically not dangerous to humans, they can be painful. The venom from their forcipules is used to subdue prey but can cause localized pain and swelling in humans.
- Indicators of Other Pests: The presence of centipedes in your home often indicates a larger pest problem, as they feed on other insects. Controlling centipedes may also involve addressing the underlying pest issues.

Preventing Centipede Infestations
Effective prevention is key to keeping centipedes out of your home. Here are some strategies to consider:
- Reduce Moisture: Centipedes thrive in moist environments. Use dehumidifiers in basements and other damp areas to reduce humidity levels. Fix any leaks in plumbing and ensure proper ventilation in bathrooms and kitchens.
- Seal Entry Points: Inspect your home for cracks and gaps around doors, windows, and the foundation. Seal these entry points with caulk or weatherstripping to prevent centipedes from entering.
- Remove Debris: Keep your home and yard free of debris such as leaves, grass clippings, and wood piles, which can provide hiding places for centipedes. Indoors, regularly clean areas where centipedes are likely to hide, such as basements and closets.
- Proper Drainage: Ensure that water drains away from your home’s foundation. Clean gutters regularly and consider installing downspout extensions to direct water away from the house.
Millipede vs Centipede
What’s the difference between millipedes and centipedes? Millipedes and centipedes are both arthropods, not insects, but they differ in behavior and impact. Millipedes are slow-moving decomposers that eat decaying plant matter and are generally harmless. Centipedes are fast-moving predators that hunt insects and are mildly venomous, though rarely dangerous to humans. Both are attracted indoors by moisture, but centipedes usually indicate the presence of other pests.
| Question | Millipedes | Centipedes |
|---|---|---|
| Is it an insect? | No. Arthropod (class Diplopoda). | No. Arthropod (class Chilopoda). |
| Is it harmful to humans? | Usually no; harmless, may release mild defensive fluid. | Usually low risk; venomous, bites uncommon and typically mild. |
| What does it eat? | Dead plants and decaying organic matter. | Insects, spiders, and other small pests. |
| Where does it live? | Damp soil, mulch, leaf litter; may enter during wet weather. | Under rocks/logs; indoors in damp areas like basements and bathrooms. |
| How many legs? | Two pairs per body segment. | One pair per body segment. |
| How fast does it move? | Slow. | Fast and agile. |
| Life expectancy | ~1–7 years depending on species. | ~1–6 years depending on species. |
| Why is it in my house? | Excess moisture or heavy rain. | Moisture and presence of insects (food source). |
What to Do If You Have Centipedes
If you already have an infestation, here are some steps on how to get rid of centipedes from your home and manage the problem:
- Traps: Sticky traps can be placed in areas where centipedes are commonly seen. These traps help capture centipedes and other pests, providing insight into the level of infestation.
- Insecticides: Residual insecticides can be applied around the perimeter of your home and in areas where centipedes are likely to enter. Be sure to follow the manufacturer’s instructions and safety guidelines when using chemical treatments. Many insecticides you can purchase at the store do have higher toxicity rates than products that professional pest control companies utilize—so be careful.
- Professional Pest Control Services: For persistent or severe infestations, consider enlisting the help of a professional pest control service like Green Pest Management to get rid of centipedes. Our experienced technicians can assess the situation and recommend targeted treatment options to effectively control centipede populations.
- Ongoing Maintenance: Regularly inspect and maintain your home to prevent future infestations. This includes addressing moisture issues, sealing entry points, and keeping your home clean and free of debris.

Are centipedes dangerous?
Centipedes are generally not considered dangerous to humans. They do not transmit diseases and they do not damage wood, wiring, or household structures. Most species are reclusive and avoid light and human activity. If threatened, some species can bite in self-defense. In most cases, the effects are limited to temporary pain, redness, and mild swelling.
How many legs does a centipede have?
Centipedes have one pair of legs attached to each body segment. The total number of legs varies widely depending on the species. Many common house centipedes have about 15 pairs of legs, while larger species may have over 100 pairs. The total number of leg pairs is always an odd number. Despite their name, centipedes do not have exactly 100 legs.
What do centipedes eat?
Centipedes are active predators that feed on other small animals. Their diet includes insects such as ants, cockroaches, silverfish, termites, and spiders. Larger species may also consume worms or small invertebrates. They capture prey using speed and inject venom to immobilize it. This feeding behavior helps naturally reduce populations of other pests.
Are centipedes venomous?
Centipedes are venomous, meaning they produce venom to subdue prey. The venom is delivered through modified front legs rather than through a stinger. The strength of venom differs among species. In humans, symptoms are typically mild and short-lasting. Significant medical complications are rare.
How to get rid of centipedes?
Effective control focuses on reducing moisture, since centipedes require humid environments to survive. Lowering indoor humidity with ventilation or dehumidifiers makes conditions less favorable. Sealing cracks and gaps around foundations, doors, and windows prevents entry. Eliminating other insects reduces their available food source. Consistent sanitation and moisture management help prevent recurring activity.
What is a centipede?
A centipede is an elongated, multi-segmented arthropod belonging to the class Chilopoda. It has a flattened body and one pair of legs per segment. Centipedes are primarily nocturnal predators. They use venom to capture and immobilize prey. They are commonly found in soil, leaf litter, under rocks, and in damp indoor areas.
Are centipedes insects?
Centipedes are not insects, although both belong to the broader arthropod group. Insects have three main body sections and six legs. Centipedes have many body segments and numerous legs. They belong to a separate biological class. These anatomical differences clearly distinguish them from true insects.
Do centipedes bite?
Centipedes can bite, but it is uncommon and usually happens only if they are handled or accidentally pressed against the skin. They use modified front legs, called forcipules, to inject venom primarily for hunting prey. In humans, a bite typically causes mild, localized pain, redness, or slight swelling similar to a bee sting. Serious reactions are rare, though individuals with allergies or sensitive skin may experience stronger symptoms.
Are centipedes poisonous?
No, centipedes are not poisonous, but some centipede species are venomous. That means the centipedes do not become harmful if touched or eaten, but they can inject venom through specialized front legs called forcipules. Most common household centipedes have mild venom that they use to subdue prey like insects and spiders, and their bite is usually comparable to a bee sting for humans. Severe reactions are rare, though people with allergies or sensitive skin may experience more noticeable swelling or discomfort.
What do centipedes eat?
Centipedes eat other small pests – centipedes are carnivorous predators. Their diet includes insects, spiders, silverfish, cockroaches, ants, termites, and even small worms. House centipedes help control indoor pest populations because they actively hunt in dark, damp areas such as basements and bathrooms. They use their venom to immobilize prey before consuming it.
How to get rid of house centipedes?
To get rid of house centipedes, focus first on reducing moisture and removing their food sources. These pests thrive in damp environments, so using a dehumidifier, fixing plumbing leaks, and improving ventilation can significantly reduce their habitat. Sealing cracks, gaps around doors, and foundation openings helps prevent entry. Because centipedes feed on other insects, controlling underlying pest problems like ants or cockroaches is essential for long-term prevention.
Are house centipedes poisonous?
House centipedes are not poisonous, but they are mildly venomous. Their venom is designed to capture prey and is generally not dangerous to humans. In rare cases, a bite may cause localized redness, swelling, or mild pain. However, house centipedes are typically shy and avoid human contact.
Are centipedes harmful?
Centipedes are generally not harmful to people or property. They do not spread diseases, damage structures, or contaminate food like some other household pests. In fact, they can be considered beneficial because they prey on insects that may cause infestations. The primary concern for homeowners is their unsettling appearance rather than actual danger.
What does a centipede look like?
Here is how a centipede looks: it has a long, flattened body divided into multiple connected segments, each with one pair of legs. Their coloration ranges from yellowish-brown to reddish or dark brown, depending on the species. House centipedes have very long, delicate legs and extended antennae, giving them a spider-like appearance. They move quickly and are often spotted darting across floors or walls, especially in humid areas of a home.
