Earwigs are an outdoor insect that keeps finding your door.
Earwigs live in damp organic material — mulch beds, leaf litter, under stones and landscape timbers — and come indoors when it gets dry outside or when heavy rain floods them out. They don't reproduce indoors and they don't establish. Which means the fix is almost entirely about the first three feet outside your foundation.
What we look for
Earwig complaints follow weather. Dry spells and heavy rain both push them toward the house.
- Insects in basements, garages, and ground-floor bathroomsEntry is usually at grade — under door thresholds, through weep holes, and around utility penetrations.
- Concentration under mulch and landscape timbersLift a section of mulch against the foundation and you'll typically find them clustered underneath if they're the source.
- Ragged feeding damage on ornamentalsIrregular holes in leaves and flower petals, particularly dahlias, marigolds, hostas, and lettuce. Damage appears overnight because they feed after dark.
- Activity spiking after rainSaturated soil drives them to higher, drier ground, which frequently means the foundation and then the interior.
- Gathering under exterior door mats and plantersAny flat object held against damp ground creates ideal daytime harborage right at an entry point.
- Sightings around exterior lightingThey're drawn to lights at night, which puts them at the door and window frames where entry is easiest.
How we handle earwigs
- Inspect the foundation zoneThe first three feet out from the wall is where the problem lives. Mulch depth, plant material against siding, ground-contact wood, and drainage all get evaluated.
- Reduce harboragePulling mulch back from the foundation, thinning excessive depth, removing ground-contact debris, and raising planters and stored items off the soil.
- Correct moisture at the perimeterDownspout extensions carrying water away from the wall, correcting grading that slopes toward the house, and clearing gutters that overflow onto the bed below.
- Seal at gradeDoor sweeps, threshold gaps, weep hole screening, and sealing around utility penetrations. Same exclusion work that keeps out several other ground-level pests.
- Perimeter treatmentA targeted band application at the foundation and in harborage areas, plus granular bait in landscape beds where activity is heavy. Our 3A certification covers the ornamental and turf side.
They do not go into your ears
We're going to say it plainly because it comes up on nearly every call. Earwigs do not crawl into ears, do not burrow into brains, and do not lay eggs in people. The name traces to an old European folk belief and possibly to the ear-like shape of the hind wing. The pincers can deliver a pinch if you handle one, but they aren't venomous and can't break skin meaningfully.
The mulch conversation
Deep mulch banked against a foundation is close to ideal earwig habitat: damp, dark, and protected. It's also a common contributor to carpenter ant, millipede, and termite problems. We're not going to tell you to remove your landscaping — but pulling mulch back six inches from the siding and keeping it under three inches deep changes the pressure on the house substantially, and costs nothing but an afternoon.
They're actually useful outdoors
Earwigs are omnivores that eat aphids, mites, and insect eggs alongside plant material. In a garden that isn't being damaged, they're doing more good than harm. The goal on a service call is keeping them out of the structure, not eliminating them from the property — which is both unnecessary and, in a landscape this size, not achievable.
