House centipedes (Scutigera coleoptrata) are not considered dangerous to humans. These centipedes are more of a nuisance than a threat. Here's a breakdown of their characteristics and their interactions with humans:
House centipedes are typically yellowish-gray with elongated, flattened bodies and numerous legs. They are often found in homes, especially in damp areas like basements, bathrooms, and crawl spaces. While they can be startling due to their appearance and rapid movements, they are not venomous or harmful to humans. In fact, they play a beneficial role by preying on other household pests like spiders, ants, silverfish, and cockroaches, helping to control the populations of these more problematic pests.
These centipedes are generally reclusive and prefer to hide in dark, secluded areas. They are primarily active at night, which is when they emerge to hunt for insects. While they may occasionally venture into living spaces, they do not bite humans unless they feel threatened. Their bite, while rare, may cause mild pain, redness, and swelling, but it is not considered medically significant. In most cases, it can be treated with basic first aid and does not require professional medical attention.
To prevent encounters with house centipedes, it is advisable to reduce their access points by sealing cracks and crevices in your home, ensuring proper ventilation and reducing moisture levels in basements and other damp areas. Using insect screens on doors and windows can also help keep them outdoors. If you find house centipedes in your home, the best course of action is to gently capture and release them outside or to use non-lethal methods to control their presence, such as reducing their prey (other insects) by implementing pest control measures.
House centipedes are not dangerous to humans and can actually be beneficial by helping to control other household pests. Understanding their behavior and taking preventative measures can minimize their presence in your living spaces.
Are House Centipedes Harmless?
Yes, house centipedes (Scutigera coleoptrata) are generally considered harmless to humans. These arthropods may appear unsettling due to their elongated bodies and numerous legs, but they do not pose a significant threat. Here's what I mean:
House centipedes are not venomous, and their bite, while rare, is not medically significant. If they feel threatened or cornered, they may bite, which can cause mild pain, redness, and swelling, but these symptoms are typically not severe and can be managed with basic first aid. The vast majority of people who encounter house centipedes do not experience any adverse effects from them.
In fact, house centipedes are often considered beneficial to have in homes because they prey on other household pests. They are voracious hunters and feed on insects like spiders, ants, silverfish, and cockroaches. By doing so, they assist in controlling the populations of these more problematic pests, which can be a natural form of pest control.
These centipedes are primarily active at night and prefer to hide in dark, secluded areas. They are rarely found in living spaces, but when they do appear, it's usually due to their search for prey or changes in their environment. They are not interested in human food or causing any damage to property.
To minimize encounters with house centipedes, it's advisable to take preventive measures such as sealing cracks and crevices in your home, maintaining proper ventilation, and reducing moisture levels in areas where they might be present. Using insect screens on doors and windows can also help keep them outdoors. If you find house centipedes in your home, gentle capture and release outside or non-lethal pest control methods are the best approaches to deal with them.
House centipedes are harmless to humans and can be beneficial due to their role in controlling other household pests. Understanding their behavior and taking appropriate precautions can help ensure coexistence with these creatures without any significant concerns for your health or well-being.
Do House Centipedes Bite?
Yes, house centipedes are capable of biting, but their bites are rare and generally not a significant concern for humans.
Frequency of Bites: House centipedes are known for being reclusive creatures that avoid direct contact with humans. They typically only bite when they feel threatened or cornered. Bites from house centipedes are relatively rare, and most people will never experience one.
Effects of Bites: When a house centipede does bite, it can cause mild localized pain, redness, and swelling. These symptoms are generally not severe and can be managed with basic first aid. Allergic reactions to house centipede bites are exceedingly rare.
Venom: House centipedes do possess venomous glands in their jaws that they use to immobilize and digest their prey. However, their venom is not harmful to humans. It is primarily intended for subduing small insects and other arthropods, not for defending against larger animals like humans.
Preventing Bites: To avoid being bitten by house centipedes, it is advisable to exercise caution when handling them and to use a gentle approach if you need to capture or remove one. If you encounter them in your home, it's best to leave them alone or use non-lethal methods to encourage them to move outdoors.
Beneficial Role: While house centipedes are capable of biting, it's important to note that they are generally considered harmless and are often even beneficial. They help control other household pests like spiders, ants, silverfish, and cockroaches by preying on them, which can serve as a form of natural pest control.
House centipedes can bite when they feel threatened, but their bites are not typically a cause for concern. These creatures are more inclined to avoid humans and are generally harmless. Understanding their behavior and taking precautions to reduce encounters with them is often the best approach to coexisting with house centipedes in your home.

Are House Centipedes Poisonous?
House centipedes (Scutigera coleoptrata) do possess venom, which they use to immobilize and digest their prey, primarily other insects and small arthropods. However, their venom is not considered dangerous or poisonous to humans. Here's a comprehensive explanation of house centipede venom:
Venom Composition: The venom of house centipedes is not well-documented in terms of its chemical composition, but it is generally considered to be of low toxicity to humans. It is designed to subdue and break down the bodies of their prey, which are typically much smaller insects.
Effect on Humans: While house centipedes can deliver a bite if they feel threatened or cornered, the effects of their venom on humans are typically limited to mild, localized symptoms. This can include some pain, redness, and swelling at the site of the bite. Allergic reactions to house centipede venom are extremely rare.
Not Poisonous: To be clear, "poisonous" typically refers to organisms that can harm you when ingested or touched, while "venomous" refers to creatures that inject venom through a bite or sting. House centipedes are considered venomous due to their ability to deliver venom via their fangs but are not considered poisonous because they are not harmful if ingested or touched.
Beneficial Role: Despite their ability to produce venom, house centipedes are generally harmless to humans and can even be considered beneficial. They play a crucial role in controlling the populations of other household pests, such as spiders, ants, silverfish, and cockroaches. Their presence in your home can help with natural pest control.
House centipedes are indeed venomous, but their venom is not dangerous or poisonous to humans. Their bites are rare, and when they occur, they typically result in mild, localized symptoms. These creatures are more inclined to avoid humans and serve as helpful contributors to pest management by preying on other household pests.
