Stink bugs and seasonal indoor invaders in Abbotsford
Agricultural surroundings can host strong outdoor populations near certain crops and hedgerows. Homes become overwintering targets when sun-warmed walls and roof voids offer cracks. Interior mass appearance is usually entry, not “hatching from nothing.”
Why they collect on sunny walls and attics
South and west exposures draw aggregations before cold weather. Attic voids and false ceilings hold quiet clusters until warm interior days wake them downward into living spaces.
Inspection: entry routes and overwintering voids
We trace roofline, vent screens, window channels, and door weatherstrip failure lines. Photo documentation helps when proofing quotes follow.
Treatment and timing realism
Interior reduction may be part of the plan, but durable improvement usually includes sealing pathways before the next aggregation season. We avoid fear copy and set expectations from what we can verify.
Exclusion and proofing that actually helps
Metal screen, vent caps, and sill detail beat spray alone on upper entries. Seepest proofing andentry point exclusion when gaps are repeatable year to year.
