What changes in Courtenay
Four property checks for Courtenay
A nest at a doorway or play area is a different problem from occasional wasps visiting flowers or food.
Use the indoor evidence to guide an exterior exclusion check at the nearest doors, pipes and foundation joints.
Follow the route toward food, water or an exterior gap before treating the visible line of ants.
Look for the moisture condition behind the activity—leaks, condensation or drainage—then choose control around that finding.
Match the plan to the building
Work outward from the room or exterior edge where the evidence is strongest. Attached housing puts more emphasis on shared walls and service routes; detached homes add the full perimeter, garage and roofline.
Make one or two explainable changes first and watch the result. That is more useful than broad treatment when the source has not been confirmed.
Before using a pesticide, confirm that it is registered for use in Canada and that the label covers the exact pest and location. The label guide links the official registry.
British Columbia and Courtenay: rule check
For household pest work, separate the federal product question from the local-use question. The Canadian label sets the approved use; British Columbia and the municipality may impose additional limits.
