What changes in Langley
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 Langley
Before treatment, identify what the ants are reaching and how they are getting there.
If insects cluster in damp areas, fix the moisture source before repeated treatment becomes the routine.
A nest at a doorway or play area is a different problem from occasional wasps visiting flowers or food.
Check garage doors, pipe penetrations, crawlspaces and lower-level gaps before cooler weather increases pressure indoors.
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.
Photograph useful signs and mark the activity location. That record helps separate identification from guesswork and makes follow-up more meaningful.
Do not substitute a foreign label or a retailer description for the Canadian product label. The pesticide-label guide explains how to verify the current registered use.
British Columbia and Langley: rule check
Federal registration answers whether a product is authorized in Canada. The label answers how it may be used, while British Columbia and local bylaws can add another layer.

Township of Langley — Rodent control
The Township’s useful local layer is rodent control on private property: it places prevention and control on property owners, emphasizes sanitation, exclusion and trapping, and cautions against poison because of risks to pets, children and wildlife. It also requires a qualified pest-control company to complete a rodent-abatement declaration before a building-demolition permit is issued. That is different from Langley City’s landscape-pesticide bylaw.
