Earwigs look more alarming than they usually are, but finding them in the kitchen, bathroom, basement, or tucked under patio cushions gets old fast. The most reliable fix is not one dramatic treatment. It is drying out the places they hide, closing easy entry points, and using a simple trap only where you are seeing activity.
Start With the Conditions Earwigs Like
Earwigs prefer cool, dark, damp cover. They often gather under wet mulch, stacked pots, dense groundcover, patio furniture, trash cans, and piles of leaves. Indoors, they usually show up after wandering in from those outdoor hiding spots rather than because they are nesting deep inside the house.
That is good news for a homeowner: the first pass is mostly cleanup and moisture control. Before reaching for sprays, walk the outside wall nearest the room where you are seeing them. Look low, especially where soil, mulch, siding, patio edges, and hose bibs meet.
A Simple Earwig Cleanup Plan
Use this as a one-hour reset around the problem area. You do not need to renovate the whole yard. Focus on the first few feet around the foundation, patio, porch, or garden bed where earwigs are appearing.
- Pull damp mulch, leaves, and plant debris back 6 to 12 inches from siding and door thresholds.
- Fix dripping hose bibs, irrigation overspray, clogged gutters, or low spots that keep the wall damp.
- Move firewood, stacked pots, cardboard, and dense clutter away from the house.
- Trim groundcover so air can move through beds near doors and basement windows.
- Check weatherstripping, door sweeps, pipe penetrations, and small foundation cracks.
If your bigger issue is general yard debris, the cleanup steps in Backyard Debris Cleanup Guide pair well with this job. Earwig control is much easier when wet hiding places are not being rebuilt every week.
Seal the Easy Entry Points
Earwigs can squeeze through small gaps, especially around garage doors, basement entries, sliding doors, and utility penetrations. After the area is dry and cleaned up, seal the obvious paths.
- Replace torn door sweeps or add a threshold seal where light shows under the door.
- Use exterior-grade caulk on small cracks around trim, sill plates, and utility lines.
- Add fine mesh or repair screens on crawl-space vents and basement windows.
- Keep mulch and soil below the siding line so the wall can dry after rain.
Use a Low-Mess Earwig Trap Overnight
Traps are useful when you want to reduce activity without spraying the whole area. Set them at dusk and check them in the morning.
- Put a small amount of vegetable oil in a shallow container, such as a tuna can or jar lid.
- Add a drop of soy sauce or a tiny bit of fish-based bait if the trap needs more pull.
- Place the trap near the patio edge, garden bed, garage threshold, or foundation area where earwigs are showing up.
- Empty and reset for a few nights, then stop once activity drops.
For a dry hiding trap, roll damp newspaper or corrugated cardboard into a tube, place it near the problem area overnight, then bag and discard it in the morning. This is especially handy near garden beds where oil traps are awkward.
When Garden Damage Is Part of the Problem
Earwigs sometimes chew tender seedlings, soft petals, and ripening fruit, but they also eat decaying material and some smaller pests. If the garden damage is minor, habitat cleanup and traps are usually enough.
Where seedlings are being hit hard, protect the most vulnerable plants first. Clear mulch right around stems, water early in the day so beds dry by evening, and use traps along the bed edge rather than broadcasting treatment across the whole garden.
If you are managing several pest pressures at once, the practical ideas in backyard mosquito control solutions and keeping flies off the patio can help you tighten up moisture, food, and cleanup habits across the same outdoor zones.
Should You Use Diatomaceous Earth or Sprays?
Diatomaceous earth can help in dry cracks, around patio edges, and in sheltered spots where it will not immediately get wet. Apply lightly, avoid breathing dust, and keep it away from flowers where pollinators are active. It works poorly once damp, so it is not a substitute for fixing moisture.
Outdoor insecticide should be a narrow backup, not the first move. If you use one, follow the label exactly, keep it away from edible plants unless the label permits that use, and target cracks, thresholds, and known hiding areas. Broad spraying often misses the source and can create more problems than it solves.
Earwig Control Checklist by Area
| Area | What to Check | Best First Fix |
|---|---|---|
| Foundation beds | Wet mulch, leaves, dense groundcover | Pull material back and improve airflow |
| Patio or porch | Damp cushions, planters, cracks, clutter | Dry, sweep, and set overnight traps |
| Garage entry | Door gap, threshold debris, stored cardboard | Replace sweep and clear storage from the wall |
| Garden beds | Seedling damage, heavy mulch, evening watering | Trap at the edge and water earlier in the day |
| Bathroom or basement | Nearby outdoor moisture, gaps, plumbing penetrations | Fix the outside source and seal small openings |
When to Call a Pest Professional
Most earwig problems are manageable with cleanup, sealing, and targeted traps. Call a professional if you are seeing heavy activity in multiple rooms, cannot find the outside source, have repeated moisture problems near the foundation, or need treatment around sensitive areas where label choices matter.

Bottom Line
The cleanest way to get rid of earwigs is to make the area less comfortable for them: dry it out, remove cover, seal the easy gaps, and trap only where activity remains. Start outside the wall where you are seeing them indoors. That one habit keeps this from turning into a spray-first guessing game.
