Getting rid of earwigs in the house usually means cutting off the moisture and dark, cluttered spaces that draw them in from outside in the first place. Vacuuming up the ones you see indoors works better than squashing them, and sealing gaps around doors and windows, plus any cracks at the foundation, keeps new ones from replacing them. Cutting back mulch and leaf litter against the house, along with fixing anything nearby that holds standing water, removes the outdoor conditions that attract earwigs to a home in the first place. Most earwig problems clear up within a couple of weeks once the moisture and entry points are addressed.
You flip on the bathroom light at night and something small and reddish-brown with pincers on its tail end scurries under the sink. Earwigs showing up inside a house is common across the Upstate, especially once conditions outside turn too dry, too wet, or otherwise uncomfortable for them.
It’s an unsettling thing to see up close, but an earwig indoors is rarely a sign of anything more serious than a gap somewhere letting them in. Getting rid of earwigs in the house comes down to a handful of consistent steps rather than one single fix.
Why Earwigs End Up Indoors
Earwigs are drawn to moisture, and a house often has more of it available than the yard does during a dry stretch or after a heavy rain pushes them out of soil that’s suddenly too wet. They’re active at night and spend the day tucked into tight, dark spots, which is why most earwig sightings happen in a bathroom, basement, or laundry room rather than out in the open.
An earwig infestation rarely starts indoors. It starts outside, in mulch beds, in stacked firewood, or in leaf litter close to the foundation, and the earwigs already living there move inward once those spots no longer work for them. A house with damp basement corners or leaky pipes gives earwigs a reason to stay once they’ve made it inside.
Those pincers on an earwig’s tail end look more alarming than they are. Earwigs use them mostly for defense against other insects. While a large earwig can pinch hard enough to notice, they don’t bite the way people sometimes assume they will.
Signs of an Earwig Problem
A few signs tend to show up together, and noticing the pattern early makes earwig control easier.
- Earwigs found near sinks, tubs, or damp basement corners
- Small pinch marks or ragged edges on tender plants near the foundation
- Earwigs turning up under flower pots, mulch, or stacked wood outside
- Noticeably more activity at night than during the day
None of these on their own means a house has a serious problem, but seeing several together usually means conditions outside are pushing earwigs toward the house.
Getting Rid of Earwigs Already Inside
- Vacuum up earwigs you find rather than squashing them, since squashing leaves a mess and doesn’t address what drew them in
- Run a dehumidifier in a damp basement or crawl space to remove the moisture earwigs are after
- Seal gaps around doors and windows, plus any cracks in the foundation
- Fix leaky faucets or pipes that keep a spot damp longer than it should be
Earwigs found indoors are usually a handful that made it in through an existing gap, not a colony reproducing inside the walls. Clearing out the ones already inside and closing off how they got there is normally enough to stop it.
DIY traps made from rolled-up damp newspaper can catch a few strays overnight, and they’re a decent way to confirm an earwig problem. They’re less useful as a long-term fix on their own, since they only catch what’s already inside rather than addressing why more keep arriving.
What Keeps Earwigs From Coming Back
Earwig control outside matters more than anything done indoors, since a house with the right outdoor conditions will keep sending earwigs inside no matter how many get vacuumed up.
Pulling mulch and leaf litter back a few inches from the foundation, fixing gutters that dump water against the house, and keeping firewood stacked away from exterior walls all remove the damp hiding spots earwigs rely on.
Fall is when this usually matters most in the Upstate, since earwigs move toward shelter as outdoor temperatures start dropping the same way several other pests do this time of year. A house that’s already sealed up and clear of damp mulch beds near the foundation has a lot less pulling earwigs toward it once that seasonal shift starts.
Earwig season looks a little different depending on where you are in the Upstate, which is part of why we’ve broken down earwig control in Simpsonville separately, alongside the more general picture here. Earwigs aren’t the only pest that shows up around doors and basement windows once outdoor conditions shift; crickets follow a similar pattern, drawn by the same light and moisture that attract earwigs.
How Earwig Control Fits In
Earwigs are a common household pest that our regular quarterly treatment is designed to handle as part of the broader exterior service. Treating around the foundation and gutters, along with nearby mulch beds, during a standard visit is usually enough to keep earwig activity from building up between visits.
Most homeowners never need anything beyond that regular service once the outdoor conditions are addressed, though a heavier-than-usual earwig season, especially after a wet summer, sometimes calls for an extra visit focused on the exterior. That’s part of why keeping a consistent quarterly schedule tends to work better against earwigs than calling only once activity is already noticeable indoors.
If you’re not sure whether what you’re seeing is an earwig, a cricket, or something else entirely, our pest library is worth a look before deciding how urgent the problem actually is.
We’ve handled earwig calls for homeowners across the Upstate since 1974, and the pattern is almost always the same: fix the moisture and entry points outside, and the earwigs inside stop showing up. That holds true for a single earwig near a bathroom sink and for a heavier season after a wet summer. Give us a call at (864) 301-6535, and if they come back, we will too.
