Why Vancouver has more rodent activity than most Canadian cities
Mild winters + sea-level access + dense restaurant corridors + ageing infrastructure = year-round rodent activity, not the seasonal activity most Canadians expect.
Vancouver's mild Pacific winters mean rodents don't get the months-long deep-cold pause they get in most of Canada. Norway rats and house mice stay reproductive year-round in any sheltered indoor habitat, which means a single mouse you saw in October can become twenty by Christmas if conditions are right. Most Canadian homeowners are conditioned to think of rodent issues as a winter-only problem; in Vancouver, the population activity is constant.
Add Vancouver's restaurant density and the legacy Strathcona / downtown / Chinatown sewer infrastructure (some of which dates to the 1890s) and you have a Norway rat reservoir that feeds the surface population continuously. The Strathcona corridor, the downtown / West End restaurant zones, the Yaletown converted-warehouse blocks, and the back-alleys of Mount Pleasant and East Vancouver all see consistent commercial-source activity that radiates out into adjacent residential. The pattern is similar in Richmond and parts of Burnaby; Vancouver's just bigger.
House mice are the other half of the picture. They're a different species (Mus musculus) with different habits — drier, smaller, more residential-focused. The 1925 Craftsman in Kitsilano with the original cedar-shingle roof, original beadboard basement walls, and the inevitable 6mm gap somewhere along the foundation seam is textbook house mouse habitat. A single breeding pair establishes; six weeks later you have a colony. Treatment without exclusion is a renewable revenue model, not a solution.
Identify what you're dealing with — rats vs mice
The treatment approach differs between Norway rats and house mice, so identification matters. Quick reference:
| Sign | Norway rat | House mouse |
|---|---|---|
| Body length | 20-25cm + tail nearly as long | 7-10cm + tail similar length |
| Weight | 300-500g | 15-30g |
| Droppings | 12-20mm long, capsule-shaped, blunt ends | 3-6mm long, rod-shaped, pointed ends |
| Typical indoor location | Basement, crawlspace, lower-floor walls, sub-grade | Upper-floor walls, attic, kitchen + pantry zones |
| Entry point size | 12mm gap or larger | 6mm gap (pencil-width) is enough |
| Smell | Strong urine smell, often from sub-grade nesting | Lighter musky odour from pheromone-rich urine |
| Activity time | Mostly nocturnal | Mostly nocturnal but some daytime |
Our Vancouver rodent control method
Find the source. Seal the entry. Then treat. Photo report inside 30 minutes.
Most rodent control failures in Vancouver happen at the diagnosis stage, not the treatment stage. Setting traps without finding + sealing the entry point is whack-a-mole. New rodents replace the trapped ones within days, sometimes hours. The exclusion work is what stops the cycle.
Find the entry
25-point inspection across the perimeter (especially the foundation seam, utility penetrations, gas meter, hose bib, dryer vent), the attic (vents, soffits, roof-junction gaps), the crawlspace (if accessible), and the kitchen + pantry interior. We're looking for rub marks (greasy dark trails along travel routes), gnaw marks, droppings concentrations, and the gap that's letting them in. The diagnosis is the work.
Seal the entry
Physical exclusion done with the right materials. Steel wool + foam at small gaps, copper mesh at vents, 1/4-inch hardware cloth at attic ventilation, silicone for plumbing penetrations, weather-stripping at garage doors. We don't use expanding foam alone — rodents chew through it. Every exclusion point is documented in your photo report.
Then trap
Snap-trap deployment is our default. We place professional-grade traps in inverted T patterns along travel routes (not random spots), baited and pre-set in a way that makes them hard to bypass. Tamper-resistant bait stations are used selectively where snap-traps aren't viable (multi-unit settings with ongoing activity, commercial). We do NOT use second-generation anticoagulants near greenbelt or wildlife-edge locations — too much documented secondary-poisoning impact on raptors.
Follow-up
30-day return inspection at no extra charge. Check trap status, inspect for any new rub marks or droppings, confirm exclusion points are still sealed (rodents will probe them for weeks). If the population is gone we wrap up; if there's continued activity we redesign.
Our position on second-generation anticoagulant rodenticides
Second-generation anticoagulant rodenticides (SGARs — bromadiolone, brodifacoum, difethialone) are highly effective single-feed killers, and they have well-documented secondary-poisoning impacts on raptors and other predators that consume poisoned rodents. The BC Ministry of Environment has been progressively restricting their use in residential applications since 2021. We've taken the position that they're rarely the right tool for residential Vancouver work.
Specifically: we lead with snap-trap deployment + first-generation anticoagulants only where chemical control is genuinely needed. We use SGARs only in commercial situations (typically food-service or healthcare) where alternatives have failed and where the risk-benefit is documented. We do not use SGARs at all in residential applications adjacent to greenbelt, parks, or wildland — North Vancouver, West Vancouver, parts of Coquitlam + Maple Ridge — where raptor exposure risk is real.
If a competitor is recommending SGAR baits for your residential property without explaining the alternatives, get a second opinion. The default-to-SGAR approach is convenient for the operator and risky for the ecosystem.
60-day return guarantee
If rodent activity returns within 60 days of your treatment, we come back. No charge. Standard practice for our return visits is a fresh diagnosis — not a respray. If activity returned, we missed an entry point, or a new activity source emerged. Either way, we figure it out.
No contracts. About 60% of Vancouver rodent customers stay on a quarterly maintenance plan because the year-round activity makes proactive trap monitoring + exclusion checks valuable. 40% take a one-time service and renew if they ever have an issue again. Either is fine.
