How to Get Rid of Earwigs Indoors? | Stop the Invasion

Spotting an earwig scurrying across your bathroom floor at night is unsettling, but the pincer-tailed pests are more of a nuisance than a danger. The key to getting rid of earwigs indoors isn’t reaching for a spray can — it’s removing the ones you see, then cutting off the moisture and entry points that invited them in.

This guide covers the physical removal methods that work immediately, why indoor pesticides usually miss the mark, and the long-term fixes that keep earwigs outside where they belong. You’ll also find simple traps you can set tonight with items already in your kitchen.

What Brings Earwigs Inside The House?

Earwigs wander indoors for two reasons: they’re looking for moisture, or they slipped in by accident. They thrive in damp, organic conditions — think mulch beds, leaf litter, and wet soil — so a humid basement, a leaking pipe, or a damp bathroom makes your home look inviting.

University of California’s Statewide IPM Program notes that earwigs are attracted to moist, shady areas and may enter homes through gaps under doors, window screens, or foundation cracks. They’re nocturnal, so you’ll usually spot them at night or in the morning near sinks, tubs, or houseplants where water collects.

Light also plays a role. Porch lights and bright exterior lighting draw earwigs to the building, where they then find their way inside.

Immediate Removal: What Works Right Now

When you see an earwig indoors, skip the spray and pick up a vacuum or broom. Sweep or vacuum the earwig up, then empty the catch into a bowl of soapy water to kill it — this prevents it from crawling back out and reinvading. For single stragglers, a paper towel works fine.

After removing what you see, target the places they hide. Earwigs squeeze into tight, dark spaces during the day, so check:

• Under potted plants and plant saucers
• Along baseboards and in closet corners
• Around window sills and door thresholds
• In damp basements, garages, and crawl spaces

Vacuum these areas regularly, especially in corners and crevices where debris collects. Removing the hiding spots makes your home far less hospitable than simply killing the ones you happen to see.

Why Indoor Sprays Usually Fail

Here’s the honest truth: spraying indoors rarely solves an earwig problem. The University of California IPM program states plainly that indoor pesticide use won’t prevent earwigs from entering and isn’t recommended as a prevention strategy. Earwigs are coming from outside, and a surface spray inside does nothing to stop the next one from walking through the same gap.

Your effort is better spent on the exterior. Inspect the foundation, door frames, window screens, and utility pipe entries for gaps and cracks, then seal them with caulk or weatherstripping. The North Carolina State University extension also recommends cleaning gutters and making sure water drains away from the foundation, since standing moisture near the house is an open invitation.

For persistent problems, some extension guidance permits a residual insecticide applied around the foundation and entry points as an exterior, crevice treatment. Use only products labeled for that site and pest, and follow the label exactly — this is a perimeter measure, not a substitute for sealing and drying.

Simple Traps And Long-Term Prevention

Traps let you catch earwigs by the dozens without chemicals. A shallow container, like an empty tuna can, baited with a little vegetable or fish oil works well — earwigs climb in for the scent and can’t get back out. Rolled-up damp newspaper placed in problem areas overnight gives them shelter; in the morning, shake the catch into soapy water. Check traps daily and refresh the bait.

Long-term prevention comes down to three habits the University of Minnesota extension emphasizes: reduce moisture, remove shelter, and seal the structure.

Start indoors by fixing leaky faucets and pipes, using a dehumidifier in damp basements, and clearing any standing water. Outdoors, move mulch, leaf litter, and firewood away from the foundation, and keep grass and vegetation trimmed. Swap bright white exterior bulbs for yellow or sodium-vapor lights, which attract far fewer insects.

Combined, these steps dry out the conditions earwigs need and block the routes they use — the same strategy extension services across the country recommend.

FAQs

Are earwigs dangerous to people or pets?

Earwigs are not dangerous. They don’t sting, and their pincers are too weak to break human skin, though they may give a tiny pinch if handled roughly. They won’t damage your home’s structure or contaminate food, making them purely a nuisance pest rather than a health threat.

Will earwigs go away on their own indoors?

Occasional stragglers will die off or wander back out, but an ongoing problem won’t resolve itself. As long as your home offers moisture, hiding spots, and easy entry points, earwigs will keep finding their way in. Drying problem areas and sealing gaps are what stop the cycle.

Do dryer sheets or essential oils repel earwigs?

There’s no evidence that dryer sheets or essential oils repel earwigs reliably. These home-remedy claims circulate online but lack support from university extension sources. Your most effective options are physical removal, traps, moisture control, and sealing entry points — methods with proven track records.
