Stink Bugs control — prevention & targeted treatment
Stink bugs (often brown marmorated) enter homes in fall seeking winter shelter. They're harmless indoors but a smelly, persistent nuisance.
Signs to look for
- Shield-shaped bugs appearing in fall and winter
- Clusters around windows, doors, and light fixtures
- A distinctive odor when disturbed or crushed
- Large numbers in attics or upper floors
Prevention (starts before the pest does)
- Seal gaps around windows, doors, siding, and vents
- Repair window screens and weather stripping
- Caulk utility penetrations and foundation gaps
- Move exterior plants away from walls
Safe DIY limits
- Vacuum them up (dispose of the bag)
- Avoid crushing them — they release odor
- Seal entry points before fall
Eco-friendly approach
Because they're shelter-seeking, control is mostly exclusion and vacuuming — least-toxic methods fit this pest naturally.
