Why Earwigs Are Common in La Jolla
Earwigs thrive in moist, shaded areas — making irrigated California landscapes ideal habitat. They hide under mulch, rocks, pavers, potted plants, and leaf litter during the day, then become active at night. Heavy earwig populations often move indoors seeking moisture during hot, dry periods.
While earwigs don't cause structural damage or carry disease, they're a nuisance pest that homeowners find alarming due to their pincers. Large populations can also damage garden plants, seedlings, and fruit.
Our treatment targets earwig harborage zones in the landscape and creates a perimeter barrier to prevent indoor entry. Reducing moisture around the foundation is key to long-term control.
How We Handle Earwigs
- Granular treatments in mulch beds, under pavers, and around landscape features
- Perimeter barrier along foundation to prevent indoor entry
- Treat under potted plants, stepping stones, and decorative rock

No. Despite their alarming pincers, earwigs don't bite or sting in any meaningful way and don't carry disease. They're a nuisance pest that most homeowners simply don't want inside their home.
Earwigs move indoors when conditions outside become too hot or dry. They enter through gaps around doors, windows, and foundation cracks, usually seeking moisture in bathrooms and kitchens.
Reduce moisture near the foundation — fix irrigation overspray, clean gutters, and move mulch away from the structure. Our perimeter treatments add another layer of protection.
Earwigs can pinch with their rear pincers if handled, but they rarely do. The pinch is mild and not dangerous. They're a nuisance pest, not a health threat.
In large numbers, earwigs can damage seedlings, flowers, and soft fruit. Our landscape treatments reduce populations while keeping your garden healthy.
Yes — earwigs are drawn to exterior lighting at night, which often brings them closer to entry points. Switching to yellow or sodium vapor bulbs can reduce attraction.
