Earwigs are elongated, dark insects with distinctive pincers at the rear, belonging to the order Dermaptera. Despite their intimidating appearance and the viral social media warnings that often accompany their photos, they are not dangerous to humans. The old myth that they crawl into ears and burrow into the brain is completely false; they seek cool, damp places with organic matter and have no interest in human bodies. Their pincers can deliver a mild defensive pinch if handled, but they are non-venomous, do not sting, and pose no real health risk.
Finding earwigs inside a home is less about the insect itself and more a signal of underlying property conditions. These moisture-loving scavengers thrive in damp environments, so their presence usually points to excess humidity, leaks, poor ventilation in basements or bathrooms, or gaps in the building’s exterior sealing such as cracks in the foundation, damaged screens, or missing door sweeps. In some cases they may also indicate hidden wood rot or water damage that creates dark, sheltered voids.
To deal with them effectively, start by sealing entry points: install door sweeps, caulk foundation cracks and utility penetrations, and repair screens. Next, reduce moisture by using dehumidifiers, fixing leaks, improving drainage around the foundation, and keeping mulch and vegetation away from the walls. For active populations, simple tools like food-grade diatomaceous earth dusted in dry cracks or homemade oil-and-soy-sauce traps can reduce numbers without harsh chemicals.
In short, earwigs are more of a symptom than a threat. Addressing the dampness and structural gaps that attract them provides long-term control and improves the overall condition of the home, while the dramatic online warnings can safely be ignored.
