Earwigs, with their distinctive appearance, often trigger concerns about their potential to harm humans. Many wonder if they are dangerous or if they bite. This apprehension stems from their common name and intimidating pincers. Understanding earwigs can help dispel these fears.
Do Earwigs Bite People?
Earwigs do not possess mouthparts capable of biting humans. Instead, they are equipped with a pair of prominent, forceps-like appendages called cerci at the end of their abdomen. These cerci are primarily used for defense against predators, capturing prey, aiding in reproduction, and assisting in folding their wings. If an earwig feels threatened, such as when picked up or accidentally pressed against skin, it might use these pincers to pinch.
The sensation of an earwig pinch is typically minor. Most often, it feels like a slight nip or a gentle squeeze, similar to a mild pinch from a person. In rare instances, the pinch might be strong enough to leave two small red marks or even break the skin, but this is uncommon. Earwigs are not venomous and do not inject toxins.
What to Do if Pinched by an Earwig
If you experience an earwig pinch, they do not transmit diseases. Gently remove the earwig from your skin without crushing it. After removal, thoroughly wash the affected area with soap and warm water. Should the skin be broken, applying a topical antibacterial cream or antiseptic can help prevent potential infection.
While the discomfort is usually mild and temporary, an ice pack can reduce any redness or swelling that might occur. Medical attention is rarely necessary; however, if the pincers break off in the skin, or if signs of infection like increasing redness, swelling, or persistent pain develop, consulting a healthcare professional is a sensible precaution.
Understanding Earwigs: Facts and Myths
Earwigs belong to the insect order Dermaptera, with approximately 2,000 species found worldwide. They are typically small (0.2 to 2 inches), with flattened bodies, often brown or black. These insects are primarily nocturnal, seeking shelter during the day in dark, moist crevices such as under rocks, logs, leaf litter, or in damp basements.
Earwigs are omnivores, feeding on both plant and animal matter. They commonly feed on decaying vegetation, fungi, and various plants, including fruits, vegetables, and flowers. Some species also prey on small insects like aphids and caterpillars, making them opportunistic feeders.
The most persistent myth surrounding earwigs is that they crawl into human ears to burrow into the brain or lay eggs. This old wives’ tale, which likely contributed to their name, has no scientific basis. Earwigs have no interest in entering human ears, and while it is theoretically possible for any small insect to accidentally enter an ear canal, it is an extremely rare occurrence and not a typical behavior.
