Why Rat Control Is a Particular Issue in New Westminster
The Fraser River is the most significant Norway rat waterway corridor in Metro Vancouver. New Westminster is built on a hillside rising directly from the Fraser River's north bank — the entire southern edge of the city is in the direct foraging and travel radius of one of the largest urban rat populations in the region. The Fraser's network of drainage channels, tidal flats, and riparian vegetation provides year-round rat harbourage that connects to Queens Park, Sapperton, Uptown, and every other New Westminster neighbourhood through the hill's drainage corridors.
Queens Park's Victorian and Edwardian heritage homes — some dating to the 1880s — have the oldest crawl-space construction in Metro Vancouver. Original concrete crawl vents from the early 1900s, settling sill-plate lines, and pipe penetrations that have been failing for decades create the entry geometry that Norway rats from the Fraser River corridor exploit consistently.
The Brunette River and Brunette Creek provide secondary rat corridors into Sapperton from the Burnaby direction.
What drives rat pressure in New Westminster:
- Fraser River waterway corridor: One of the largest Norway rat populations in Metro Vancouver — year-round pressure on all New Westminster residential near the waterfront and through the hill's drainage corridors.
- Queens Park heritage crawl-space construction: 1880s to 1920s original crawl vents and sill-plate lines with the most accumulated entry geometry in Metro Vancouver.
- Brunette River/Creek corridor: Secondary rat connectivity from Burnaby into Sapperton.
