The long-standing notion of earwigs deliberately crawling into human ears has instilled fear. This common urban legend prompts questions about their actual behavior. Understanding the truth requires examining scientific facts about earwigs and practical advice for rare instances of insect entry into the ear canal.
Dispelling the Earwig Myth
Earwigs do not actively seek to enter human ears, and an occurrence of this nature is exceedingly rare. The persistent myth likely stems from their Old English name, “Δ“are-wicga,” which translates to “ear wiggler” or “ear creature.” Historically, people mistakenly believed these insects would bore into the brain or lay eggs inside the ear. However, earwigs are not interested in human ears as a habitat. Their prominent pincers, which appear menacing, are primarily used for defense, mating, or grasping prey, and they are generally harmless to humans, rarely breaking skin.
Understanding Earwig Behavior and Habitat
Earwigs are nocturnal insects that prefer dark, moist environments. They typically hide during the day under rocks, logs, leaf litter, mulch, or in cracks and crevices. Their diet is omnivorous, consisting of decaying plant and animal matter, as well as small insects like aphids. Earwigs are scavengers that play a role in decomposition, helping to break down organic material in their natural habitats. Their primary interest lies in finding suitable damp shelter and food sources within their environment, not in human ear canals.
What to Do If an Insect Enters Your Ear
While earwigs rarely enter ears, any small insect can accidentally find its way into the ear canal. If this happens, it is helpful to remain calm. First, tilt your head to the side with the affected ear facing downward and gently shake it to try and dislodge the insect. Avoid inserting objects like cotton swabs or tweezers, as this can push the insect deeper or damage the eardrum.
If the insect is still alive and the eardrum is known to be intact, a small amount of body-temperature mineral oil or baby oil can be poured into the ear canal to suffocate or float the insect out. If the insect is dead, warm water can be used to gently flush it out, again only if the eardrum is known to be intact. Prompt medical attention should be sought if the insect cannot be removed, if there is pain, discharge, hearing loss, or any concern about eardrum integrity.
