Do Centipedes Bite Humans? Symptoms & First Aid
Centipedes are fast-moving, creepy-looking creatures that can easily startle anyone who spots them darting across the floor.
But beyond their frightening appearance, many people wonder, do centipedes bite humans? The answer is yes, but it is not as simple or scary as it might sound.
In this article, we will explore whether centipedes pose a real threat, which species are most likely to bite, what those bites feel like, and when you should seek medical attention.
Let us separate the facts from the fear so you know exactly what to do if you cross paths with one of these many-legged pests.
Facts About Centipedes
Centipedes are fascinating animals that live in different habitats all around the world. They play a vital role in managing pest populations, but their bites can cause pain and worry for those who come into contact with them.
It is important to recognize the signs of centipede bites to effectively identify and address any negative reactions.
The word “centipede” is derived from Latin, where it means “hundred feet,” because these creatures appear to have many legs. These animals should be viewed as beneficial since they are strictly predatory.
Centipedes are elongated arthropods that are active at night and consist of many segments, each typically having a pair of legs except for the last one.
The first set of legs on their head has transformed into pincer-like structures called forcipules, which they use to inject venom into their prey.
The final segment features two long, tail-like appendages that, contrary to popular belief, do not help with venom delivery.
Centipedes primarily feed on a variety of prey they can overpower, making them generalist carnivores. They thrive in many different places, ranging from lush tropical rainforests to dry deserts.
However, since they lack the protective waxy coating found in insects and arachnids, centipedes need moist environments to prevent rapid water loss.
To stay hydrated, they avoid direct sunlight by hiding or being active during nighttime.

What Do Centipedes Look Like?
Centipedes can vary in size, measuring anywhere from less than 1 inch to up to 7 inches long. They typically have between 15 pairs of legs and can have up to 177 legs, but they always have an odd total number of legs.
These creatures prefer dark, moist environments and thrive in wet climates, but they can also adapt to deserts and other dry regions. Centipedes are found nearly everywhere around the world.
They can be found in various places such as basements, floor drains, concrete blocks, crawl spaces, forests, and gardens.
You might find them hiding under decaying logs or rocks, in potted plants, underwater, or even deep inside caves.
Do Centipedes Bite Humans?
Do centipedes bite humans? Yes, centipedes are capable of biting humans. Although they are not aggressive, they may bite if they feel threatened or upset.
Their bite can be quite painful and might lead to redness, swelling, and inflammation.
Most reactions are mild and typically fade within a few hours to a few days; however, some individuals might experience more severe symptoms or allergic reactions due to the centipede’s venom, although this is rare.
Generally, no treatment is necessary for a centipede bite unless someone has a serious allergic reaction. Over-the-counter medications for itching and pain can help alleviate discomfort.
Symptoms usually resolve within a short time, with little chance of long-term issues.
When a centipede bites, it injects venom through its fangs located in specialized mouthparts called forcipules.
They use this venom to defend themselves and catch their food. If a centipede feels threatened by a person, it may resort to biting.
Centipedes are carnivorous creatures that feed on insects and worms using their venomous bite; they are not typically hostile toward humans but will react if provoked.
All centipedes possess venom that helps them kill their prey, but bites rarely lead to serious health issues in people and are not usually life-threatening.
In rare cases, larger centipede species can inject enough venom to cause nausea, sweating, fever, chills, or even severe allergic reactions like anaphylaxis.
Fatalities from centipede bites are uncommon; there have only been a few well-documented incidents, such as one involving a child bitten on the head and another where a bite on the throat resulted in choking.
Certain centipedes have venom that includes different toxins, such as histamine, serotonin, and a toxin that can slow down the heart.
While it is uncommon for bites from centipedes to cause widespread effects, it is crucial to understand that these toxins can lead to serious allergic reactions in individuals who are sensitive to bee and wasp stings.
They can also result in notable cardiovascular and neurological issues.
How Do Centipedes Bite or Sting?
Centipedes use the sharp, claw-like legs on their first body segment to bite and break through skin. They might bite if someone picks them up roughly or steps on them by accident.
Although all centipedes are capable of biting, smaller varieties might not have enough strength to break through human skin.

What are the Signs of a Centipede Bite?
Centipede bites are marked by two tiny puncture wounds where they inject venom into your skin. The area surrounding the bite may turn red and swell up.
The level of pain you experience depends on how much venom is injected. Smaller centipedes release very little venom, making their bites feel similar to bee stings in terms of discomfort.
In contrast, larger centipedes can inject more venom, resulting in sharp pain.
You will notice pain, redness, and swelling right after being bitten. These symptoms can persist for anywhere from a few hours to several days.
Other symptoms might appear as well, which could signal a serious allergic reaction, such as the following:
- fever
- chills
- nausea
- Severe swelling at the bite site
- swollen lymph nodes
- heart palpitations
- itching
What to Do if Bitten by a Centipede?
Centipede bites may look similar to those from other venomous insects. If you are uncertain about what bit you, it is wise to see a doctor, particularly if your symptoms are serious.
If there are no complications, treating a centipede bite focuses on easing the symptoms and can often be managed at home:
- Quickly apply heat to the bite. Soaking the area in hot water or using hot compresses helps dilute the venom.
- Use ice packs to lessen swelling.
- Take medications for pain relief, allergic reactions, and inflammation, like antihistamines, anesthetics, and anti-inflammatory drugs.
