It often starts after dark: a scratching or scurrying inside the walls, a few dark droppings behind the stove, or a chewed corner on a cereal box in the pantry. Rats are cautious and mostly nocturnal, so by the time you see one in daylight or hear them overhead, there are usually more than one, and they breed fast. A single pair can turn into a serious infestation in a matter of months. Surrey sits along the Fraser River and the Serpentine and Nicomekl floodplains, which gives it some of the highest rat pressure in the Lower Mainland, and the mild coastal winters mean the pressure barely lets up. The Province of BC lists rats and mice among the pests most likely to damage buildings and spread disease.
The good news: rats are very controllable once you stop chasing the ones you can see and start closing off how they get in and where they nest. For fast, local help, our team handles rat control in Surrey from inspection through exclusion, and if you already know you need a hand, a professional rat exterminator in Surrey will find the entry points and runways a quick DIY pass almost always misses.
Quick answer
Rats are active in Surrey year round, with a strong push indoors in fall and winter as the weather cools. Getting rid of them means locating nests and runways, setting a controlled baiting and trapping program, and sealing every gap larger than about a coin so they cannot re-enter.

Rats breed fast
One breeding pair can become dozens before winter. The sooner you act, the smaller the job.
Call 604-589-3338Droppings
Dark, capsule-shaped pellets 12 to 19 mm long, clustered near food, sinks or along walls.
Gnaw marks & grease
Chewed edges on wood, wire and packaging, plus greasy rub marks where rats run the same path.
Night noises
Scratching, gnawing or scurrying in walls, ceilings or the attic once the house goes quiet.
Rat Season in Surrey: a Year-Round Problem
Unlike wasps or ants, rats never really take a season off in Surrey. The mild, wet coastal climate and the river corridors keep them active all twelve months. Here is how the year tends to run.
The move indoors (peak). As nights cool, rats look for warmth and food inside homes and garages. This is the busiest window and the most important time to seal up.
Settled in. Rats that got in before winter are nesting in walls, attics and crawlspaces, breeding through the cold months while food is scarce outdoors.
Spring surge. Warmer weather and abundant food drive a fast breeding cycle. Populations outdoors climb quickly along ravines, greenbelts and waterways.
Outdoor high. Summer numbers peak in yards, compost, sheds and woodpiles. Catching them outside now keeps them from moving in when fall arrives.
Rats vs. Mice: Which Do You Have?
Surrey homes get both, and they call for different traps, bait placement and entry-point sizes. Telling them apart helps you describe the problem when you call. Health Canada notes that droppings size and gnaw damage are the quickest tells.
🐀 Rats
- Body 20 to 25 cm plus a long tail
- Droppings large, 12 to 19 mm, capsule-shaped
- Norway rats burrow outdoors and low; roof rats climb
- Gnaw fist-sized holes; leave greasy rub marks
- Common along the Fraser corridor and waterways
🐁 Mice
- Body 7 to 10 cm, small and light
- Droppings tiny, 3 to 6 mm, like grains of rice
- Nest indoors in walls, insulation and clutter
- Squeeze through gaps as small as 6 mm
- Curious, so they investigate new traps quickly
DIY first? Snap traps and store baits can knock down a few rats, but rats are neophobic, meaning they avoid new objects, and they will route around a poorly placed trap for days. If you are seeing droppings in more than one room, hearing noises in the walls, or refilling bait that keeps disappearing, a targeted inspection finds the nest and the entry points faster and cheaper than weeks of trial and error. It also helps to spot the early signs of a rodent problem before it spreads.
How Pest Detective Handles Rat Control in Surrey
Pest Detective has been Canadian owned and operated since 1986, which is 40 years of local experience, technicians who live and work across Surrey, full BC Pesticide Applicator licensing, and a 4.8★ rating over 176+ reviews. Here is how a rat job runs.
Inspection & entry mapping. We follow runways and rub marks, check the crawlspace, attic and foundation, and find the gaps, vents and utility penetrations rats are using to get in, the step DIY usually misses.
Controlled treatment. We place tamper-resistant bait stations and traps where rats actually travel, sized and positioned for their caution, so the population comes down instead of just the boldest few.
Exclusion & perimeter. We seal entry points and can add exterior perimeter protection so new rats cannot simply follow the same path back in.
Follow-up & prevention. We return to confirm activity has stopped, clear stations, and flag the food, clutter and moisture issues that invited them, so it stays fixed.
Rat control programs start at $450, with in-and-out and poison-free options available, and we confirm the exact price before any work begins. Call 604-589-3338.
Where Rats Show Up Across Surrey
Surrey's rivers, floodplains and greenbelts give rats water, cover and travel routes right up to the back door. A few areas see it more than others.
Bridgeview & Newton
Right along the Fraser River corridor, where Norway rats burrow and follow storm and utility lines into homes.
Serpentine & Nicomekl floodplains
Low, wet ground and ditches keep year-round rat pressure high across Panorama Ridge and Sullivan Heights.
Whalley & Guildford
Older homes and busier lots offer plenty of gaps, garbage and shelter for rats to move between properties.
Cloverdale & South Surrey
Farmland, chicken coops and acreage outbuildings draw rats to feed, then into nearby houses and garages.
Rats are just one of the pests moving through the city right now. See what else is active around Surrey this season so nothing catches you off guard.
Keep Rats Out: Surrey Prevention Checklist
- Seal gaps around pipes, vents, dryer outlets and the foundation; rats push through openings the width of a coin.
- Keep pet food, birdseed and pantry staples in sealed metal or hard plastic containers, never open bags.
- Move compost, woodpiles and yard debris away from the house, and secure garbage and green-bin lids.
- Cut back ivy, shrubs and tree limbs that touch the roof or siding, since these act as rat ladders.
- Fix leaks and improve drainage; a reliable water source keeps rats close to the building.
Once they are out, the goal is keeping them out. It helps to seal rats and mice out of your home for good with a full exclusion pass.
Year-round option
Tired of rats finding their way back every fall?
Surrey's mild winters mean rat pressure never fully stops. PD Shield 365 rodent monitoring bundles ongoing exterior monitoring visits with perimeter treatments into one simple plan, so rats are caught at the fence line instead of in your kitchen.
Rat Control FAQs — Surrey
Why does Surrey have so many rats?
Surrey sits along the Fraser River and the Serpentine and Nicomekl floodplains, with ravines and greenbelts throughout. That means water, cover and food year round, and the mild coastal winters let rats stay active when colder regions see a pause.
I only saw one rat, is that really a problem?
Usually yes. Rats are cautious and nocturnal, so seeing one, especially in daylight, often means a larger group is already established nearby. Rats also breed quickly, so acting early keeps the job small.
When is rat season in Surrey?
Rats are active all year here, but activity indoors peaks in fall and winter as they move inside for warmth and food. Outdoor numbers climb through spring and summer, which is why year-round monitoring works best.
How much does rat control cost in Surrey?
Rat control programs start at $450, with in-and-out and poison-free options available. The final price depends on the size of the problem and the home, and we confirm it before any work begins.
Do you offer fast rat service in Surrey?
Yes. We prioritize urgent rodent calls and work to get a technician to your Surrey home as quickly as possible.
