Earwigs: Complete Identification & Control Guide

Earwigs are one of the most misunderstood household pests. Despite the old myth that they crawl into human ears, these nocturnal insects are mostly nuisance invaders that seek out dark, damp spaces in and around your home. The good news? With the right knowledge and professional-grade products, earwig problems are very manageable on your own. This guide covers everything you need to know to identify, treat, and prevent earwig infestations.

What Does an Earwig Look Like?

Earwigs are elongated, flat-bodied insects that typically measure between 5/8 inch and 1 inch in length. They range in color from dark brown to reddish-brown, often with lighter tan or yellowish markings on their legs and the edges of their wings. Their most recognizable feature is the pair of pincer-like appendages, called cerci, that extend from the tip of their abdomen. Males tend to have curved, wider-set pincers, while females have straighter, narrower ones.

Earwigs have six legs, two antennae that are roughly half the length of their body, and a segmented, slightly shiny exoskeleton. While many species have wings, they rarely fly. If you spot a small, fast-moving insect with prominent pincers scurrying away when you lift a rock or a flower pot, you're almost certainly looking at an earwig.

Signs of an Earwig Infestation

Earwigs are nocturnal, so you may have a significant population before you ever see one during the day. Here are the most common signs to watch for:

  • Live sightings at night: Turn on a light in a dark bathroom, kitchen, or basement and you may catch earwigs out in the open. They scatter quickly when disturbed.
  • Damage to plants and seedlings: Earwigs feed on soft plant tissue, leaving ragged, irregular holes in leaves, flower petals, and young seedlings — especially in gardens close to your home's foundation.
  • Gathering under objects: Lift up mulch, pavers, stones, newspapers, or potted plants near your home and discover clusters of earwigs huddled together in the moisture beneath.
  • Faint, foul odor: When crushed or threatened, earwigs can release a mildly unpleasant yellowish liquid from scent glands on their abdomen. In large populations, this smell can become noticeable.
  • Small dark droppings: Earwig frass is tiny and pellet-like, sometimes found near baseboards, in cabinets, or around damp areas where they congregate.

Where Earwigs Hide

Earwigs are moisture-seeking insects, so they gravitate toward the dampest areas in and around your home. Outdoors, they hide under mulch, landscape timbers, leaf litter, rocks, and compost piles. They're commonly found beneath potted plants and in garden beds close to the foundation.

Indoors, earwigs typically congregate in basements, crawl spaces, laundry rooms, bathrooms, and kitchens — anywhere humidity levels are elevated. They also hide in door frames, window sills, and behind baseboards. Cracks in the foundation, gaps around utility pipes, and poorly sealed door sweeps all serve as entry points. They're often drawn inside during periods of extreme heat, drought, or heavy rain.

Health & Property Risks

Earwigs are not considered dangerous to humans. They do not transmit diseases, and while they can use their pincers to deliver a mild pinch if handled, it rarely breaks the skin and is not venomous. They are not known to cause allergic reactions in most people.

From a property standpoint, earwigs do not cause structural damage to homes. They don't bore into wood or chew through wiring. However, they can cause cosmetic damage to indoor houseplants and significant damage to outdoor gardens, particularly to young seedlings, soft fruits like strawberries, and ornamental flowers such as dahlias and marigolds. Large populations can become a persistent nuisance, especially when they invade living spaces in numbers.

How to Get Rid of Earwigs: DIY Treatment Steps

Earwig control is highly effective with a targeted, multi-step approach. Here's a treatment plan you can follow using professional-grade products:

  • Step 1 — Reduce moisture and harborage: Before applying any products, address the conditions that attract earwigs. Fix leaky faucets, improve drainage near your foundation, and remove debris like leaf piles and stacked wood from around your home's perimeter.
  • Step 2 — Apply a perimeter granular bait: Spread an insecticidal granular bait around the exterior foundation of your home, in garden beds, and near entry points. Earwigs are attracted to the bait and consume it, making this one of the most effective outdoor treatments.
  • Step 3 — Apply a residual barrier spray: Using a professional-grade liquid insecticide, treat a 3-foot band around the foundation, along door thresholds, window frames, and any cracks or crevices where earwigs may enter. This creates a long-lasting barrier that kills earwigs on contact and continues working for weeks.
  • Step 4 — Treat indoor harborage areas: Apply a crack-and-crevice treatment along baseboards, behind appliances, under sinks, and around plumbing penetrations in kitchens and bathrooms. A light dust formulation works well in wall voids and hard-to-reach spaces.
  • Step 5 — Use traps for monitoring: Place sticky traps or simple rolled-up damp newspaper traps in problem areas to monitor earwig activity and gauge whether your treatments are working.

Pest Remedy kits include the right combination of professional-grade products for each of these steps, along with clear instructions tailored to earwig control. Everything you need arrives at your door — no guesswork required.

Prevention Tips

  • Seal entry points: Caulk cracks in the foundation, install or replace door sweeps, and seal gaps around pipes and utility lines entering your home.
  • Reduce exterior moisture: Ensure gutters drain away from the foundation, fix irrigation leaks, and avoid overwatering garden beds near the house.
  • Minimize mulch depth: Keep mulch to 2 inches or less and maintain a 6-inch gap between mulch and your home's foundation to reduce harborage areas.
  • Remove debris: Clear leaf litter, stacked firewood, and unused landscape materials away from the perimeter of your home.
  • Improve ventilation: Use dehumidifiers in basements and crawl spaces, and ensure bathroom exhaust fans are functioning properly to reduce indoor humidity.
  • Switch exterior lighting: Replace white outdoor lights with yellow or sodium vapor bulbs, which are less attractive to earwigs and other insects that may draw them closer to your home.

When to Call a Professional vs. DIY

For the vast majority of earwig problems — from occasional invaders to moderate infestations — a DIY approach with professional-grade products is more than sufficient. Earwigs respond well to barrier treatments, baits, and moisture management, all of which homeowners can apply effectively with the right guidance and materials.

You might consider calling a licensed pest control professional if you're dealing with an extreme, recurring infestation that persists despite multiple treatment cycles, or if you suspect the earwig activity is a symptom of a larger
