What attracts earwigs? Earwigs are attracted to moisture, darkness, decaying organic matter, and sheltered hiding spots. They need high humidity above 75 percent to survive, so damp dark places like basements, bathrooms, crawl spaces, laundry rooms, under sinks, and areas with leaks attract them. Outdoors, they are attracted to mulch, leaf litter, compost piles, wood piles, decaying plant material, and under rocks, boards, and logs where they can hide during day and find food like decaying matter and small insects. They are attracted to lights at night, which may draw them toward houses. Food sources like decaying plant material, small insects, aphids, and soft plant material attract them as they are omnivorous. Clutter providing hiding spots also attracts. So what attracts earwigs is moisture, dark sheltered areas, decaying organic matter near foundation, mulch, leaf litter, lights at night, and entry points like cracks and gaps that allow them to enter homes seeking damp shelter, especially during wet or dry extremes.
