In late summer, boxelder bugs and Asian lady beetles love the warmth of the afternoon sun on south and west-facing walls. Bug clusters gather, then slip indoors through hairline gaps to overwinter. Bug-smart prep begins with filling gaps. Caulk around utilities and trim. Check weatherstripping on doors and windows. Repair or replace torn screens, and place tight mesh covers over vents.

Lights act like a porch-side beacon. Warm-tone bulbs, shielded fixtures and closed shades at dusk reduce attraction without sacrificing visibility. In the landscape, prevention is tough, but regular cleanup limits interest. Trim vegetation and leaf litter back from siding. Stack firewood off the ground and away from the house. 

If a few wanderers appear indoors, vacuum to remove them. Avoid crushing, which can stain or smell and even invite more to visit. Broad insecticide use becomes far less necessary when tight seals, smart lighting and simple housekeeping carry the load. When extra help is needed, seek a knowledgeable, professional, eco-conscious resource partner.
