Earwigs in your house in Williamsburg are seeking moisture and shelter, especially during hot, dry, or excessively wet weather. They are outdoor insects that live under mulch, stones, and leaf litter, but when conditions outside become unfavorable, they enter homes through gaps under doors, foundation cracks, and spaces around utility penetrations. Once inside, they gravitate toward the dampest areas including bathrooms, kitchens, and basements. Professional perimeter treatment around the foundation creates a barrier that stops earwigs before they enter. Reducing moisture near the foundation by improving drainage and managing mulch depth, combined with sealing entry points, provides long-term prevention.
