Stink Bug, Boxelder Bug & Lady Beetle Control Ottawa
Every fall they gather on sunny walls and look for a way inside to overwinter.
What you need to know
Stink bugs, boxelder bugs, and lady beetles do not infest a home the way ants or mice do. In fall they gather on warm, sunny walls and squeeze into gaps to overwinter, then reappear indoors on warm winter days and in spring. They do not breed indoors, but large numbers become a real nuisance. The best results come from treating the exterior before they settle in and sealing the gaps they use.
Covered under the PestPass Plan ($159/visit, quarterly, $636/year) and the One-Time Treatment ($249/visit, 30-day guarantee). See plans & pricing →
Warning signs
- ✓Clusters on south- and west-facing walls, window frames, and eaves in fall
- ✓Insects crawling on windows or curtains during warm winter days
- ✓Many insects collecting in attics, wall voids, or upper rooms
- ✓A noticeable smell when stink bugs are disturbed or crushed
What to expect
Check sunny exterior walls, window and door frames, soffits, and common gaps.
Treat the building exterior where they gather and enter, ideally before fall clustering peaks.
We point out the gaps around windows, doors, and utility lines that let them in.
Vacuuming is the safest way to remove the ones that get inside; crushing stink bugs releases their odour.
