What changes in Saint John
Four property checks for Saint John
Repeated traffic into one opening can indicate a nest; casual feeding activity alone does not establish that.
Basements, crawlspaces, kitchens and exterior drainage deserve attention where persistent moisture is present.
Seal practical entry points and correct accessible food sources so trapping is not the only control measure.
Before spraying, follow the activity long enough to locate the likely entry point or source.
Match the plan to the building
A room-by-room response is not always enough: consider how walls, utilities, garages and exterior openings connect the affected area to the rest of the building.
Keep the treatment proportional to the problem. A single entry route, pantry source or reachable nest calls for a different response than recurring activity across several rooms.
Physical controls can often reduce the problem before any chemical step. When a pesticide is appropriate, the Canadian label—not a social post or foreign product page—sets the allowed use; see the label guide.
New Brunswick and Saint John: rule check
For household pest work, separate the federal product question from the local-use question. The Canadian label sets the approved use; New Brunswick and the municipality may impose additional limits.
