Across Nevada, especially in cities like Las Vegas, Reno, Henderson, and growing suburban communities across the desert valleys, many families occasionally discover small, brown insects hiding in bathrooms, kitchens, laundry rooms, or basements. They usually appear suddenly, often after irrigation cycles, seasonal rain, or temperature shifts. Because of their distinctive rear pincers, earwigs immediately trigger concern, and many homeowners assume an infestation has begun inside the house.
But what most Nevada families don’t realize about earwigs indoors is that these insects are rarely true indoor pests.
