Stink bugs invade every fall: what homeowners need to know
Killing the bugs you see indoors does not stop the next wave staging on the sunny exterior wall. Crushing them spreads the famous odor. The durable approach is timed exterior treatment plus sealing.
What works better than smash-and-spray
- Exterior barrier before peak invasion
- Repair screens, door sweeps, and gaps at eaves and utilities
- Vacuum carefully and empty outdoors when bugs are already inside
- Reduce harborage against siding where possible
