What Are Earwigs? Understanding These Moisture-Loving Pests

If you've ever turned over a rock in your garden or spotted a strange, pincer-tailed insect in your basement, chances are you’ve met an earwig. Despite their spooky appearance, earwigs are more of a nuisance than a threat—but they can invade your home in large numbers when outdoor conditions shift.

In this post, we’ll break down:

• What earwigs are and what attracts them
• Where they live outdoors and how they enter homes
• How they’re similar to roaches (and how they’re not)
• How to prevent an infestation
• Answers to the most common earwig-related questions

Earwig Biology: What You Need to Know

Earwigs belong to the order Dermaptera, a small group of insects known for their:

• Pincer-like cerci at the back of their abdomen (used for defense and mating)
• Elongated, flattened bodies that help them squeeze into tight spaces
• Nocturnal behavior—they hide during the day and become active at night

Why Earwigs Love Moisture

Earwigs thrive in damp, dark environments, making them common in places with:

• High humidity
• Excessive moisture from leaks, condensation, or poor drainage 
• Shaded areas with organic debris like mulch, leaves, or wood piles

This makes them a lot like cockroaches—both insects seek out similar environments, especially when it gets too dry or too hot outside.

Natural Habitat: Where Earwigs Live Outside

You’ll often find earwigs:

• Beneath rocks, logs, garden stones
• Around drainage areas like downspouts and gutter edges
• In mulch beds, leaf piles, and wood stacks

They’re most active during spring through early fall and often come inside seeking shelter or moisture when the ground dries out.

FAQ: Common Questions About Earwigs

Q: Do earwigs crawl into people’s ears?
A: This is a myth! The name "earwig" comes from old European folklore. They may wander into ear canals out of curiosity (like many bugs), but it's extremely rare.

Q: Are earwigs dangerous?
A: No, they don’t bite or sting. Their pincers may look intimidating but are harmless to humans and pets.

Q: Why am I suddenly seeing earwigs in my house?
A: They often enter homes during dry spells or after heavy rain. Moisture-seeking behavior brings them inside through cracks or vents.

Q: How can I tell the difference between earwigs and roaches?
A: Earwigs have noticeable pincers and a slimmer body. Roaches are more oval-shaped, faster, and have long antennae. Both love moist, dark areas.

Q: What’s the best way to get rid of earwigs?
A: Reduce moisture, remove outdoor debris, seal entry points, and consider a targeted pest control treatment—especially if they're showing up in large numbers.
