What's in a Name? Unpacking the 'Earwig' Moniker
The term 'earwig' conjures up unsettling images, largely due to a persistent, albeit mostly untrue, legend. But why are these distinctive insects specifically called earwigs? The answer lies deep within historical folklore and a misunderstanding of their behaviour. The name originates from an old Anglo-Saxon word, 'earwicga', which literally translates to 'ear-insect'. This peculiar nomenclature is not derived from any scientific observation of them favouring ears, but rather from a widespread superstition that they would burrow into the ears of sleeping humans. From there, it was believed they would lay eggs, feed on earwax, or even cause damage to the eardrum. This deeply ingrained belief, passed down through generations, cemented the insect's name, despite evidence to the contrary.
- The name 'earwig' comes from the Anglo-Saxon 'earwicga' meaning 'ear-insect'.
- It's based on a folk belief, not scientific fact, about them entering ears.
- This myth led to the insect being named despite no evidence of this behaviour.
The fear associated with earwigs entering ears is a significant part of their cultural perception. Ancient texts and folklore often describe them as harmful to the ear canal, leading to their ominous reputation. However, modern entomological understanding clarifies that while earwigs might occasionally seek shelter in dark, humid places, including potentially an ear if one were exposed and vulnerable, they do not actively seek out human ears. Their primary habitat is in soil, leaf litter, and beneath bark, where they forage for food and shelter. Their scientific classification, Dermaptera, means 'skin-wing', referencing the short, leathery forewings that cover their larger, membranous hindwings, which are rarely used for flight in most species.
Debunking the Myth: Do Earwigs Really Go in Your Ear?
Let's address the elephant in the room: do earwigs go into human ears? The short answer is: it's exceptionally rare and highly unlikely. Earwigs are primarily nocturnal scavengers and predators, seeking out decaying organic matter, small insects, and other invertebrates in damp, dark environments. They are not attracted to the warmth or moisture of the ear canal. If an earwig were found in an ear, it would almost certainly be accidental – perhaps the ear was exposed outdoors in an earwig-infested area, or the insect was seeking refuge and stumbled into the opening. Once inside, their primary instinct would be to escape rather than burrow or cause harm. Their characteristic pincers, or cerci, at the rear are used for defence, capturing prey, and aiding in wing folding, not for burrowing into flesh.
The persistent myth likely originated from a combination of their somewhat alarming appearance, particularly their cerci, and the fact that they are often found in dark, hidden places where one might also sleep, like under bedding or in decaying wood near homes. The fear was amplified by the lack of scientific understanding in earlier times, allowing superstitions to flourish unchecked. While it is important to be aware of potential pest issues in and around your home, the specific fear of earwigs actively targeting human ears can be largely dismissed. If you do find an earwig in your home, it is far more likely to be seeking shelter or food than plotting an invasion of your auditory canals.
The historical fear of earwigs entering ears is a myth that has unfairly shaped public perception for centuries.
The 'Earwig' Name: Etymology and Folklore
To truly understand why they are called earwigs, we must delve into the etymology and the rich tapestry of folklore that surrounds these creatures. The name 'earwig' is a direct descendant of the Old English word 'ēarewicga'. Breaking this down, 'ēare' means 'ear', and 'wicga' is thought to mean 'insect' or 'crawler'. Thus, the name literally translates to 'ear crawler'. This naming convention points towards a deep-seated cultural narrative rather than any scientific observation. Across various European cultures, similar names and beliefs existed, all revolving around the alleged tendency of these insects to invade ears.
In medieval times, the belief was so widespread that remedies were sought to prevent earwigs from entering the ears. Some folklore suggested that wearing a specific type of cap or plugging the ears with wool would offer protection. The common earwig (Forficula auricularia) is the species most often associated with these legends. Its distinctive appearance, particularly the prominent, curved pincers at its rear, likely contributed to its fearsome reputation, making it an easy target for superstitious explanations of bodily ailments or discomforts.
Cultural Beliefs and Historical Misconceptions
The historical misconception about earwigs has persisted for so long that it has become almost a part of their identity. Ancient Greek and Roman writers, while often more scientifically inclined, also mentioned the perceived danger of earwigs to human ears. This widespread belief among learned individuals lent credence to the superstition, ensuring its transmission across centuries and geographical boundaries. The lack of detailed entomological knowledge meant that such stories, however unfounded, could easily take root and flourish.
This fear also extended to what earwigs were believed to do once inside. Some tales claimed they would feed on earwax, others that they would burrow into the eardrum and lay eggs, causing severe pain and hearing loss. While earwigs do consume organic matter, including decaying insects, they have no biological mechanism or motivation to seek out and infest human ears for sustenance or reproduction. Their cerci, while formidable-looking, are adapted for grasping prey or aiding in the folding of their delicate hindwings, not for piercing or burrowing into flesh. The truth is that earwigs are generally harmless to humans, preferring to avoid confrontation and stay hidden.
The 'earwig' name is a historical label rooted in superstition, not in the insect's actual behaviour.
Beyond the Name: What Earwigs Actually Do
Given the dramatic reputation attached to their name, it's worth exploring what earwigs actually do in their natural environment. Far from being malicious invaders of human ears, earwigs are fascinating and often beneficial insects. They are primarily nocturnal, spending their days hidden in dark, moist places like under rocks, logs, mulch, or in leaf litter. As night falls, they emerge to forage. Their diet is omnivorous, consisting of a varied menu that includes decaying plant matter, fungi, other insects (like aphids), insect eggs, and small invertebrates. This makes them valuable allies in the garden for pest control.
Their distinctive pincers, or cerci, are their most recognisable feature. These are typically smooth and curved in males, and straighter in females. As mentioned, their primary uses are for defence, helping them to ward off predators, and for capturing smaller prey. Some species also use them to help fold their hindwings neatly after flight, though many earwigs are not strong fliers and tend to walk or scurry rather than fly. Their ability to fold their wings under their short forewings is quite remarkable, contributing to their compact appearance when at rest.
The Earwig's Role in the Ecosystem
The ecological role of earwigs is often overlooked due to their infamous name. In gardens and natural environments, they act as natural pest controllers and decomposers. By feeding on aphids, small caterpillars, and other garden pests, they help to keep populations of these insects in check, reducing the need for artificial pesticides. They also contribute to the decomposition process by consuming decaying organic matter, returning nutrients to the soil. This makes them an integral part of a healthy ecosystem, playing a quiet but important role in maintaining balance.
Understanding their actual behaviour and ecological function can help demystify these creatures. They are not attracted to humans or their ears. If they are found in a house, it's usually because they are seeking shelter from extreme weather, looking for food, or have accidentally wandered indoors. Their presence is more indicative of available moisture and food sources nearby than any intent to cause harm. If you find earwigs in your home, focusing on removing moisture sources and sealing entry points is a more productive approach than worrying about them entering your ears.
If you find earwigs congregating, reduce moisture and food sources in that area by clearing debris and checking for leaks.

Managing Earwigs: Practical Advice
While the fear of earwigs entering ears is largely unfounded, they can sometimes become a nuisance in homes or gardens. If you wish to manage their presence, understanding their habits is key. Earwigs thrive in damp environments. Therefore, the most effective way to deter them from your home is to reduce moisture. Check for and repair leaky pipes, ensure good ventilation in bathrooms and kitchens, and avoid leaving damp cloths or towels lying around. Outdoors, clear away leaf litter, mulch, and debris near the foundation of your house, as these provide ideal hiding and breeding grounds.
For gardens, earwigs can be beneficial. However, if their numbers become overwhelming and they start damaging plants, particularly seedlings or soft fruits like strawberries, you can take steps to manage them. One method is to create trap shelters. Roll up sections of newspaper or place overturned flower pots filled with damp straw or wood shavings in areas where earwigs are prevalent. The earwigs will congregate in these shelters during the day, allowing you to collect and dispose of them in the morning. This is a humane and environmentally friendly way to reduce their numbers without resorting to broad-spectrum insecticides.
Alternatives to Traditional Pest Control
If you are concerned about earwigs on your plants, consider using natural barriers or attractants for beneficial insects. For instance, planting certain herbs might deter earwigs from specific areas, or encouraging natural predators like birds and ground beetles can help balance the ecosystem. Companion planting can also play a role; some plants might not be as attractive to earwigs as others. When dealing with earwigs in the house, ensure that windows and doors are properly sealed to prevent entry. Simple measures like checking shoes left outdoors and shaking out clothing before bringing it inside can also prevent accidental indoor migration.
Ultimately, the name 'earwig' is a historical curiosity, born from fear and superstition rather than fact. While they may not be the ear-invading monsters of folklore, they are a part of the natural world with their own unique behaviours and ecological roles. By understanding their true nature, you can appreciate their place in the environment and address any practical concerns about their presence with reasoned, effective methods.
