Can Earwigs Bite Or Harm Humans Or Pets?

Have you ever wondered if those creepy-looking insects called earwigs could actually pose a threat to you or your beloved pets? Well, fear not! In this article, we will explore the truth behind the common misconception surrounding earwigs and their supposed harmful bites. So, sit back, relax, and let’s uncover the truth about whether earwigs can truly bite or harm humans or pets.

Can Earwigs Bite Or Harm Humans Or Pets?

What are earwigs?

Earwigs, scientifically known as Dermaptera, are a group of insects that belong to the order Dermaptera. These insects are characterized by their forceps-like appendages called cerci, which are found at the end of their abdomens. Earwigs vary in size, but most species typically range from 5 to 25 millimeters in length. They have elongated bodies with hardened wings and distinctive antennae. Overall, earwigs have a unique appearance that sets them apart from other insects.

Physical appearance

Earwigs have a distinct physical appearance that can be easily recognized. They have dark brown or reddish-brown bodies and are usually small in size. The most notable feature of earwigs is their cerci, which resemble pincers and are found at the end of their abdomens. These cerci are primarily used for defense and for capturing prey. Despite their intimidating appearance, earwigs are not harmful to humans or pets unless provoked.

Habitat and behavior

Earwigs can be found in various habitats around the world, including gardens, forests, and urban areas. They prefer dark and damp environments and are often found in areas where moisture is present, such as under rocks, logs, or in decaying vegetation. Earwigs are nocturnal creatures, meaning they are primarily active during the night. They are omnivorous insects and feed on a wide range of materials, including plant matter, other insects, and organic debris.

Can earwigs bite?

One common concern about earwigs is whether they can bite humans or pets. While earwigs do possess mouthparts that are capable of biting, they rarely bite unless they feel threatened or provoked. Their bite is not known to be venomous or harmful. It’s important to note that earwigs are generally more interested in finding food and shelter rather than seeking out humans or pets to bite.

Mouthparts of earwigs

Earwigs have mandibles in their mouthparts, which are used for chewing food. These mandibles are relatively small compared to other insect species and are not designed for powerful bites. If a human or pet comes into contact with an earwig and provokes it, the earwig may pinch or produce a mild bite as a defense mechanism.

Instances of earwig bites

Although earwig bites are relatively rare, there have been instances where people have reported being bitten. These bites, however, are usually mild and result in minimal pain and discomfort. In most cases, the bites cause small puncture wounds similar to a pinprick. It’s important to remember that earwigs are not aggressive creatures and are unlikely to bite unless provoked.

Are earwig bites harmful?

Earwig bites are generally considered to be harmless to humans. While they may cause some pain and discomfort, the effects are usually minor and temporary. However, there are a few factors to consider regarding the potential harm caused by earwig bites.

Pain and discomfort

When an earwig bites, it can cause a small puncture wound accompanied by mild pain and discomfort. The intensity of the pain can vary depending on the individual and their sensitivity to insect bites. It’s important to keep in mind that most earwig bites do not result in severe or long-lasting pain.

Infection risk

One potential concern related to earwig bites is the risk of infection. Like any wound, earwig bites have the potential to become infected if not properly cared for. It’s crucial to clean the affected area and apply appropriate first aid measures to minimize the risk of infection. In most cases, with proper care, the risk of infection from an earwig bite is low.

Can earwigs harm pets?

While earwigs are primarily considered a nuisance rather than a threat, they can potentially harm certain pets under specific circumstances. It’s important to understand the common targets of earwigs and the potential risks they pose to pets.

Common targets of earwigs

Earwigs are generally attracted to areas with moisture, which can make certain pets more susceptible to encounters. Small animals such as rodents, rabbits, and guinea pigs may be more likely to come into contact with earwigs if they are kept in environments where these insects thrive, such as damp outdoor enclosures.

Potential risks for pets

Earwigs may bite if they feel threatened or cornered by a pet. While the bites are not typically severe, they can cause discomfort or irritation to the animal. Additionally, if a pet has an allergic reaction to an earwig bite, they may experience more severe symptoms. It’s important to monitor pets for any signs of irritation or adverse reactions if they have come into contact with earwigs.

Preventing earwig bites and harm

To prevent earwig bites or potential harm to yourself and your pets, there are several proactive measures you can take. By eliminating their habitats, using natural repellents, and implementing physical barriers, you can significantly reduce the chances of encountering earwigs.

Eliminating their habitats

To discourage earwigs from residing in your immediate environment, it is essential to eliminate their preferred habitats. This includes removing debris, decaying vegetation, and organic matter from your yard or garden. By keeping your outdoor spaces clean and well-maintained, you can reduce the likelihood of earwigs finding suitable nesting spots.

Using natural repellents

Natural repellents can be effective in deterring earwigs from entering your living spaces or pet enclosures. Some common natural repellents for earwigs include essential oils like lavender, mint, or citrus. Placing these scents strategically around potential entry points can repel earwigs and discourage them from venturing further.

Implementing physical barriers

Physical barriers can be an effective way to prevent earwigs from entering your home or pet enclosures. This can include sealing cracks and crevices in your walls and foundation, installing sweeps or weatherstripping on doors and windows, and using mesh or netting to cover gaps or openings that may serve as entry points for earwigs.

What to do if bitten by an earwig?

If you or someone you know is bitten by an earwig, it’s essential to follow proper care and first aid procedures to minimize any potential complications.

Cleaning the affected area

The first step after an earwig bite is to clean the affected area thoroughly. Gently wash the wound with soap and warm water to remove any dirt or bacteria. Pat the area dry with a clean towel to avoid further irritation.

Applying first aid

After cleaning the wound, apply an antiseptic ointment or cream to prevent infection. Cover the bite with a sterile bandage or adhesive bandage to protect it from further irritation and rubbing.

Seeking medical attention

In most cases, earwig bites do not require medical attention. However, if you experience severe pain, excessive swelling, or signs of an allergic reaction, it is advisable to seek medical assistance. A healthcare professional can assess your condition and provide appropriate treatment if necessary.

Treating earwig bites in pets

If your pet has been bitten by an earwig, it’s important to take appropriate measures to alleviate any discomfort and prevent potential complications.

Recognizing symptoms

Keep an eye out for any signs of irritation, redness, or swelling around the site of the bite. Excessive scratching or licking can also indicate that your pet is experiencing discomfort. If you notice any unusual symptoms, it’s best to examine the area closely and take appropriate action.

Cleaning the affected area

Similar to human bites, it’s crucial to clean the wound on your pet’s body. Gently wash the area with mild soap and warm water, taking care to avoid further aggravation. Pat the area dry, and if necessary, apply a pet-safe antiseptic cream or ointment to prevent infection.

Consulting a veterinarian

While most earwig bites in pets are not cause for serious concern, it is advisable to consult with a veterinarian if you notice any severe symptoms or if the symptoms persist. A veterinarian can provide professional guidance and determine if any additional treatment or care is required.

Misconceptions about earwigs

There are a few common misconceptions about earwigs that are important to address to provide a more accurate understanding of these insects.

Earwigs crawling into ears

One commonly held belief is that earwigs crawl into human ears while a person is sleeping. However, this is a myth with no scientific evidence to support it. Earwigs do not have any particular attraction or inclination to crawl into ears, and there have been no documented cases of earwigs causing harm or residing in human ears.

Earwigs causing diseases

Another misconception about earwigs is that they carry and transmit diseases to humans or pets. In reality, earwigs do not pose a significant risk in terms of disease transmission. They are primarily nuisance insects and do not have the ability to spread harmful diseases.

Interesting facts about earwigs

Apart from the misconceptions and concerns surrounding earwigs, there are some interesting facts about these insects that can provide a better understanding of their behavior and biology.

Longevity and reproductive habits

Earwigs have relatively long lifespans compared to many other insects, with some individuals living up to two years. They engage in complex mating rituals, and female earwigs show maternal care by guarding their eggs and young nymphs until they are independent.

Feeding habits and diet

Earwigs are opportunistic feeders and have a diverse diet. While they primarily feed on decaying organic matter, they are also known to consume plant material, insects, and even other earwigs. Their scavenging nature helps keep ecosystems in balance by breaking down organic matter and recycling nutrients.


Although earwigs can bite if provoked, they are generally harmless to humans and pets. Their bites may cause minor pain and discomfort, but the risk of infection is low with proper care. By understanding their behavior, taking preventive measures, and knowing how to respond to an earwig bite, you can coexist with these insects without unnecessary worry. So, the next time you come across an earwig, remember that they are more of a fascination than a threat.
