Brown marmorated stink bugs seek out warm, sheltered spots in fall — attics, wall voids, soffits — and reappear indoors on mild winter days, releasing their signature odour if crushed or disturbed.
They don’t bite or breed indoors, but large numbers gathering in living spaces is a common late-fall complaint, especially in homes near fields or wooded lots.
We treat the exterior perimeter ahead of the fall migration and seal the gaps around siding, vents, and window frames that stink bugs use to get inside.

No, they're a nuisance pest only — the odour when disturbed is the main complaint, not any bite or structural risk.
Bugs that overwintered inside wall voids or attics become active again when indoor temperatures rise, mistaking it for spring.
