Rat Control in Waterloo Region
Norway rats are showing up in more Kitchener, Waterloo, Cambridge and Guelph neighbourhoods every year. Harnet uses a structured trap-and-exclude program with tamper-resistant stations, targeted trapping and detailed monitoring.
Homeowners, restaurant operators, property managers and business owners in Waterloo Region seeing rat burrows, large droppings, gnaw damage or heavy nighttime activity in walls, sheds, garages or around garbage areas.
Rats are showing up in more Ontario cities every year — Kitchener, Waterloo, Cambridge and Guelph are no exception. Construction activity, mild winters, urban garbage and rail corridors all contribute to expanding Norway rat populations across Waterloo Region.
Rat control is fundamentally different from mouse control. Rats are neophobic, cautious, and much larger — they need heavier traps, larger bait blocks, and stations placed along known runways. Sloppy rat work can drive rats deeper into structures and cause dead-animal odour problems in wall voids.
Every Harnet rat program is designed and executed by a Licensed Ontario Pesticide Applicator, using tamper-resistant equipment and a documented monitoring schedule so you know exactly what's happening on the property.
How to know you have a rat problem
- Large dark droppings (up to 20mm) near garbage, sheds or basements
- Burrow holes near foundations, decks or wood piles
- Gnaw damage on wood, plastic or garage doors
- Nighttime noise in walls, attics or crawl spaces
- Grease marks along low walls and fence lines
- Runways worn into grass or dirt against fences and foundations

Why professional rat treatment matters
Consumer rat poisons used above-ground or in open containers are illegal in Ontario for a reason — non-target risk to pets, children and wildlife is significant. Professional rat control uses locked, tamper-resistant bait stations that meet regulatory requirements.
Rats also require larger, sturdier snap traps and specific bait choices to overcome their caution around new objects. Placement is everything: a trap on the wrong side of a runway will sit untouched for weeks.
A structured program combines trapping, monitored baiting and exclusion recommendations so rats don't just die — the property becomes unattractive to the next colony.
How Harnet treats rat problems
Property Inspection
We map burrows, runways and entry points around the exterior and interior of the property.
Targeted Control
Snap trapping, tamper-resistant bait stations and precision placements along active runways.
Exclusion Recommendations
Detailed report of gaps, vents and structural defects that need sealing.
Ongoing Monitoring
Follow-up visits to service stations, track activity and adjust the program until the property is clear.
How to prevent rats from coming back
- Keep garbage in sealed rat-proof bins — not bags in the driveway
- Fill and monitor any burrow holes near foundations, decks and sheds
- Remove standing water, uncovered pet dishes and fallen fruit from yards
- Clean up bird-feeder spillage — a major food source for urban rats
- Seal gaps under garage doors, sheds and around utility penetrations
- Keep compost enclosed — open compost bins are one of the top rat attractants in urban Waterloo Region
Local relevance in Waterloo Region
Norway rat sightings have climbed noticeably in downtown Kitchener, uptown Waterloo, Galt in Cambridge and parts of Guelph over recent years. We see clusters near restaurant rows, transit corridors and older neighbourhoods with dense laneway garbage.
Because rats travel between properties, a truly effective rat program often needs to consider what's happening at the neighbouring property or business too. We'll document what we find so you have the right information to raise concerns with landlords, businesses or city services.
