Boxelder Bugs on Siding: Fall Prevention with Pyrethroids

Red-backed bugs on stones, windows, siding in Milwaukee = boxelder bugs. They seek winter shelter in cracks (south/west walls). Indoors: vacuum. Prevention (fall): spray synthetic pyrethroids (Demon WP, Demand SC, Tempo WP/SC) around eaves, vents, windows, doors, fascia, siding—focus south/southwest. Seal cracks, fix screens, plug foundation gaps. Mechanical exclusion is best long-term.
