What changes in Cambridge
Four property checks for Cambridge
Start with the route. Cleaning the attractant and closing the entry point may matter more than killing foragers.
A nest at a doorway or play area is a different problem from occasional wasps visiting flowers or food.
Exclusion comes first: check doors, utility entries, foundation gaps and attached garages for routes indoors.
Shared plumbing, walls and corridors can connect units, so isolated DIY treatment may not address the full route of activity.
Match the plan to the building
Match the inspection to how the building is connected. Common walls and service lines deserve attention in multi-unit homes; detached houses add the perimeter, garage and roof transitions.
Before treatment, note the exact location and pattern of activity. A short record of photos and physical signs helps distinguish a recurring route from a one-off sighting.
Canadian pesticide use starts with the label. The product must be registered in Canada and the label must cover the pest and location you intend to treat; the label guide shows what to check.
Ontario and Cambridge: rule check
The safest rule path is simple: current Canadian label, current Ontario requirements, then a municipal bylaw check if the treatment is outdoors or landscape-related.
