What changes in Delta
Who handles the problem in a rental or multi-unit building?
British Columbia rental starting point: BC’s Residential Tenancy Act requires landlords to maintain residential property to applicable health, safety and housing standards and suitable for occupation. Tenants must maintain reasonable health, cleanliness and sanitary standards and are responsible for damage caused by their actions or neglect. Pest responsibility therefore depends on the source and facts; it is not safe to say “landlord always pays” or “tenant always pays.” Check the official provincial source.
What the municipal source does: The municipal source on this page provides local pest, wildlife or prevention guidance. Use it for local routing and private-versus-public-property questions; it does not replace the provincial tenancy framework.
Shared-building signal: For strata or other multi-unit housing, activity inside one unit can involve common property, shared walls or service lines. Notify the owner/landlord and strata or building manager early when the source may cross unit boundaries; responsibility can depend on the strata bylaws, property boundaries and cause.
Four property checks for Delta
Repeated traffic into one opening can indicate a nest; casual feeding activity alone does not establish that.
Use the indoor evidence to guide an exterior exclusion check at the nearest doors, pipes and foundation joints.
Use the trail to identify the attractant or opening; treating only the workers can leave the source untouched.
If insects cluster in damp areas, fix the moisture source before repeated treatment becomes the routine.
Match the plan to the building
The same pest can require a different route check depending on the building. Follow shared utilities in attached housing and the full envelope on detached properties.
If the pest is well identified, start with the physical and housekeeping steps that fit the route. A pesticide is one tool, not the definition of pest control.
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.
British Columbia and Delta: rule check
A registered product still has to be used exactly as its Canadian label allows. British Columbia may add provincial restrictions, and municipalities can regulate some lawn and landscape pesticide uses.
