About Earwigs
Earwigs show up in Arizona homes and yards more than most people realize. They hide under rocks, mulch, potted plants, sprinkler boxes and shaded corners along the foundation. When the soil gets too wet or too dry, they wander into garages, bathrooms, kitchens and laundry rooms.
Their pincers look intimidating, but earwigs are mostly a nuisance pest. They do not bite or sting. The problem is that when you start seeing one, there are usually dozens more hiding nearby.
Common Earwigs in Arizona
Fromms Pest Control handles earwig problems across Phoenix, Mesa, Peoria, Scottsdale, Chandler, Glendale and surrounding cities. We target moisture pockets, foundation gaps, and landscape areas where earwigs live and breed, then treat the perimeter to keep them from entering your home.
The earwig species most commonly found in Arizona neighborhoods is the European earwig:
European Earwig
A reddish-brown earwig with noticeable curved pincers on the back end. They hide during the day and feed at night on decaying plant material and small insects. More info: European earwig on Wikipedia.
Arizona also has a few native earwig species, but homeowners mainly encounter the European earwig because it thrives in irrigated landscapes and shaded residential areas.
Where Earwigs Hide in Arizona Homes
Earwigs love moisture and shade. Around Arizona homes, they commonly hide in:
- landscape rock beds and mulch
- under potted plants and drip trays
- sprinkler and irrigation boxes
- soil along the foundation
- garage corners and storage areas
- bathrooms with condensation or leaks
- laundry rooms and baseboard gaps
If you see earwigs crawling on walls or appearing in sinks or bathrooms, they are following moisture and temperature changes inside the home.
Signs You Have an Earwig Problem
- multiple earwigs around outdoor lights or patios
- earwigs crawling along baseboards or entry points
- earwigs found in bathrooms, kitchens or laundry rooms
- damage to garden plants or leaves
- moisture buildup near the home’s foundation
Earwigs rarely appear alone. Seeing a few usually means there is an established population in your landscaping.
Why Earwigs Are Common in Arizona
Arizona’s mix of extreme heat and heavy irrigation creates perfect conditions for earwigs. They thrive anywhere with:
- moist soil from sprinklers or drip systems
- thick mulch or rock beds that stay shaded
- potted plants and planters against the foundation
- cool garage floors and undisturbed storage corners
- bathroom and laundry room condensation
Earwigs become especially active after monsoon storms and during seasonal transitions when moisture levels shift.
Are Earwigs Dangerous?
Earwigs look intimidating because of their pincers, but they are not harmful to people or pets. They may pinch if handled, but it is not venomous or medically significant. The biggest problems with earwigs include:
- creating infestations in landscaping areas
- drawing predators like spiders and scorpions
- becoming a nuisance inside bathrooms and laundry rooms
- chewing on garden plants and flowers
Since earwigs are prey for scorpions, their presence can increase scorpion activity. For scorpion removal, see our
scorpion control service.
DIY Earwig Control vs Professional Treatment
DIY sprays often dry out too fast or fail to reach the areas earwigs actually hide in. Since earwigs live in damp, shaded soil pockets, most over the counter products do not penetrate deeply enough to break the population.
Fromms Pest Control uses targeted treatments that reach the places earwigs hide, including:
- moisture pockets near the foundation
- irrigation and sprinkler zones
- rock and mulch beds
- entry points near doors and windows
- baseboards and hidden indoor cracks when needed
If earwigs are appearing indoors, they may be following moisture trails. Pairing treatment with our general pest control service helps prevent related pests like ants, roaches and spiders from establishing around the same areas.
How Earwigs Enter the Home
Earwigs enter homes through:
- door gaps and garage openings
- cracks near foundations
- utility and plumbing penetrations
- drain lines and floor gaps
- moisture damaged baseboards
They do not actively seek indoor spaces. They follow moisture, shade and cool temperatures.
Earwig Prevention Tips
- reduce overwatering or pooling irrigation around the home
- create a dry buffer zone between soil and the foundation
- move potted plants away from exterior walls
- fix leaking spigots, hoses or AC condensation lines
- seal gaps under doors and along garage frames
- keep mulch thin and avoid piling it high against the house
Earwig infestations often calm down once moisture conditions are fixed, but professional treatment ensures they do not return immediately.
