What is provincial and what is local?
New Brunswick requires professional pesticide businesses and applicators to meet provincial licensing and certification rules. Homeowners using domestic pesticides on their own property are treated differently from commercial applicators.
That pesticide rule is only one layer. Federal registration and the Canadian product label decide whether a product is authorized for a named pest and treatment site. Provincial tenancy law or policy helps frame landlord/tenant maintenance responsibility. A municipality may add property standards, waste rules, wildlife routing or a pesticide bylaw. One source should not be stretched to answer a different question.
Rental responsibility in New Brunswick
New Brunswick says tenants must maintain reasonable cleanliness and repair damage they or their guests cause. Landlords must keep the rental unit in a good state of repair and fit to live in, keep common areas clean and safe, and comply with health, safety, housing and building standards. Those duties frame a pest dispute; they do not make responsibility automatic without examining cause and property condition.
For recurring pests in a multi-unit building, notify the landlord or manager promptly and document where activity appears so common areas and connected units can be assessed if needed.
Where to escalate a problem
The Tenant and Landlord Relations Office is the provincial route for unresolved repair/maintenance disputes. Municipal enforcement may still matter where waste, property standards or nuisance-wildlife rules apply.
For a privately owned home, the owner normally handles pest activity on the property unless the city identifies a public-land, sewer, wildlife or municipal-program role. For a rental or multi-unit building, report recurring activity early and keep notes or photos of where it appears; that helps separate a property-condition issue from a treatment choice.
Pesticide and treatment safety
Start with identification, sanitation, moisture correction, exclusion and monitoring where those measures fit the pest. If a pesticide is needed, use only a Health Canada-registered product for the exact pest and site on the label. Provincial and municipal rules can be more restrictive, especially outdoors or where a professional applicator is required.
Season is a clue, not a diagnosis. Outdoor ants, wasps and some invading insects can be more noticeable in warmer periods, while bed bugs and cockroaches can persist indoors year-round. Rodent pressure can shift with weather and building conditions. The city pages use climate as an inspection prompt rather than claiming a citywide infestation rate.
How to use the New Brunswick city guides
Choose the municipality below for the local evidence layer: property standards, a pest or wildlife program, a pesticide bylaw, or—in a few smaller communities—only a general official verification route. The page labels the source scope so a City spraying program is not mistaken for permission to treat a home.
