How to Identify an Earwig (and What Those Pincers Are For)
If you’ve ever lifted a flowerpot, pulled back mulch, or moved a damp towel left outside — only to spot a quick-moving insect with what looks like pincers on its rear — you’ve probably met an earwig.
While they might look intimidating, especially with those forceps-like appendages, earwigs are often misunderstood. Let’s break down what earwigs are, what their pincers actually do, and why they may be showing up around your home.
What Is an Earwig?
Earwigs are small, flat-bodied insects that belong to the order Dermaptera. They’re most recognizable by the pair of curved pincers (called cerci) at the end of their abdomen. Despite old myths, they don’t crawl into people’s ears, nor are they aggressive toward humans.
Key Earwig Characteristics:
- Size: ½ to 1 inch long
- Color: Reddish-brown or dark brown
- Body: Slender, segmented with short wings (but rarely fly)
- Behavior: Nocturnal and moisture-loving
- Pincers: More pronounced in males; used for defense and mating rituals
What Do the Pincers Do?
While earwig pincers may look like mini weapons, they’re not dangerous to people. Earwigs use their cerci primarily for:
- Self-defense against predators
- Capturing small prey like aphids or insect larvae
- Mating displays (especially among males)
- Folding their wings (yes, they have wings — even if they rarely fly)
If you were to handle an earwig, it might try to pinch you — but the pinch is harmless and barely felt.
Where Do Earwigs Hide?
Earwigs thrive in cool, dark, and damp places, both indoors and out. You’ll most commonly find them:
- Under mulch, stones, or leaf piles
- In garden beds or flower pots
- In bathrooms, kitchens, laundry rooms, and basements
- Behind baseboards or under sinks if moisture is present
They tend to come indoors in search of shelter during dry spells or after heavy rain, especially if the conditions in or around your home are particularly moist.
Do Earwigs Cause Damage?
While earwigs are mostly considered a nuisance pest, they can:
- Feed on young plants or seedlings in gardens
- Invade homes in large numbers, especially during summer
- Occasionally damage paper products or soft fruits
However, they don’t sting, transmit disease, or pose serious risks to people or pets.
Why Are Earwigs Getting Into My Home?
Like many pests, earwigs are opportunistic. They may enter your home for:
- Moisture: Leaky pipes, damp basements, or standing water
- Shelter: Cool, dark crevices under baseboards or behind walls
- Food sources: Decaying organic matter or other small insects
If you’re spotting earwigs inside, it often signals excess moisture around your property — something worth addressing even beyond pest concerns.
How to Keep Earwigs Out
The key to preventing an earwig problem is reducing the conditions that attract them:
Outdoors:
- Clear away leaf litter, mulch buildup, and yard debris
- Trim vegetation away from your home’s foundation
- Avoid overwatering lawns and gardens
- Seal exterior gaps and install door sweeps
Indoors:
- Use a dehumidifier in damp areas like basements
- Fix plumbing leaks and improve ventilation
- Store paper products and cardboard in dry spaces
- Seal cracks along baseboards and entry points
If you’re noticing persistent activity — especially in multiple rooms — it may be time for professional treatment.
