Centipede vs. Earwig: Key Differences, Identification, and Control

When you spot a fast-moving, multi-legged insect in your home, you might wonder: is it a centipede or an earwig? Both creatures can be unsettling to encounter, but they are quite different in appearance, behavior, and their role in the ecosystem. Here’s how to tell them apart and manage them if they become a nuisance.

Centipede vs. Earwig: Quick Comparison

How to Identify a Centipede

  • Body Shape: Long and flat with clearly segmented sections.
  • Legs: Dozens of legs, giving them a rapid, slithering motion.
  • Behavior: Fast-moving, prefers dark, damp spaces like bathrooms, basements, and crawl spaces.
  • Bite Risk: Centipedes can bite if threatened, causing mild irritation, similar to a bee sting.

How to Identify an Earwig

  • Pincers: Distinctive forceps at the rear, curved in males and straight in females.
  • Body: Shorter, more compact compared to centipedes.
  • Behavior: Slower than centipedes, often found under leaves, mulch, or indoors near moisture.
  • Pinch Risk: May pinch if handled, but it’s harmless and doesn’t break the skin.

Are Centipedes and Earwigs Dangerous?

⚠️ Centipedes:

  • Bites: House centipedes have venomous bites, but they’re generally harmless to humans. Bites cause minor swelling, redness, or a burning sensation.
  • Benefit: They control pests like spiders, cockroaches, and flies.

✅ Earwigs:

  • Pinches: Can pinch when threatened, but their forceps aren’t strong enough to cause harm.
  • Myths: Despite old legends, they don’t crawl into ears or harm humans.

What Attracts Them to Your Home?

Both centipedes and earwigs are drawn to moist environments:

  • Leaky pipes, bathrooms, and basements
  • Damp laundry rooms or under sinks
  • Organic debris, mulch, and leaf piles outside

How to Get Rid of Centipedes and Earwigs

Indoor Control:

  • Reduce Moisture: Use dehumidifiers and fix leaks.
  • Seal Entry Points: Caulk cracks around windows, doors, and foundations.
  • Declutter: Remove storage boxes, papers, and other hiding spots.

Outdoor Control:

  • Clear Debris: Remove mulch, leaf litter, and woodpiles near the foundation.
  • Improve Drainage: Ensure gutters and downspouts direct water away from the house.
  • Use Traps: Sticky traps can catch both centipedes and earwigs indoors.

Natural Deterrents:

  • Diatomaceous Earth: A natural powder that dehydrates insects.
  • Essential Oils: Peppermint or tea tree oil sprays can repel both pests.
