Window Sill Warriors: Solving Overwintering Congregations (Boxelder Bugs, Cluster Flies & More)

Homeowners sometimes find dozens of harmless-but-annoying insects clustered on window sills, sun-facing siding, or inside attics. In this episode we unpack a real service call about overwintering congregations—think boxelder bugs, cluster flies, and Asian lady beetles—and turn it into an Integrated Pest Management (IPM)-first playbook. Mike and Dana walk through the clues pros look for (staining, daytime indoor sightings at sunlit windows, small entry gaps), explain why these species cluster and what attracts them, and prioritize exclusion, sanitation, and monitoring over quick fixes. You’ll get the XTERMIGATOR DIY Report: 3–5 safe, non-chemical steps to reduce arrivals tonight, plus clear red flags that mean call a licensed inspector. Warm, practical, and checklist-driven, this episode teaches durable pest prevention—how to find entry points, reduce habitat, and stop repeat visits without panic or unsafe hacks.
