Mice Control in Richmond Hill
Treated on day one, verified at three weeks, then sealed — 12-month warranty, no monthly fees. November is the peak move-in month in Ontario.
Richmond Hill backs onto the Oak Ridges Moraine, and the ravine lots and open fields around Oak Ridges, Jefferson and Bayview Hill push field mice toward warm basements every fall. Larger homes with finished basements, attached garages and complex rooflines give them dozens of ways in. Sani IQ maps the whole envelope and seals the entries — we don't just bait and leave.
Where we find them getting in around Richmond Hill
- Droppings in the garage, under sinks, or along basement and storage walls
- Scratching or scurrying in walls and ceilings at night
- Gnaw marks on food packaging, wiring or wood trim
- A musky ammonia smell in closets, pantries or the furnace room
- Activity that returns each fall as fields and ravines cool down
Full inspection + entry-point map
Exterior foundation, garage seals, utility lines, weepers, attic and kitchen kick-plates — we document every gap a mouse can use (a dime-width, about 6 mm, is enough). Most homes have 8–15 the owner has never noticed.
Treat first — exit routes stay open
Interior treatment plus tamper-resistant exterior bait stations, placed on the evidence (droppings, rub marks, gnaw patterns). We deliberately do NOT seal on day one, so mice leave the structure and die outside — not in your walls.
Return visit (~3 weeks): verify, then seal
Once activity has stopped we come back, confirm the knockdown, and seal the entry points with galvanized steel mesh, steel-wool-backed sealant and weatherstripping. Sealing at the right time is the step most companies get wrong.
Keep them out + 12-month warranty
Stations stay in and are serviced every quarter; freeze-thaw and settling open new gaps, so we re-inspect and reseal on every visit. Mice return inside the warranty? So do we — at no charge.
Where They Get In
The 8 Ways Mice Get Into Richmond Hill Homes
Our inspections in Richmond Hill find 8–15 entry points on a typical house. These are the ones that show up again and again — and the ones we seal at the ~3-week return visit, once the mice are out.
- 1 Garage door bottom seal — Worn weatherstrip = open door
- 2 Weepers & foundation cracks — 6 mm is enough
- 3 Utility & A/C line penetrations — Gas, hydro, cable, condensate
- 4 Dryer & bathroom vents — Missing or stuck flaps
- 5 Soffit & fascia gaps — Climb via downspouts and vines
- 6 Roofline & attic vents — Then straight down the wall voids
- 7 Window wells & sill gaps — Basement windows left ajar
- 8 Cantilevers & deck ledgers — Open-bottom overhangs

Mice in Richmond Hill — common questions
Why do mice keep coming back to my Richmond Hill home?
Homes near Oak Ridges and Jefferson face seasonal pressure from surrounding fields and ravines. Without sealing the entry points, new mice simply follow the same routes — exclusion is the step we never skip.
Do you treat large or multi-level homes?
Yes — we inspect the full exterior, garage, attic and mechanical rooms of larger Richmond Hill homes to find every entry, not just the obvious ones.
How do mice get into Richmond Hill homes?
The entries we find most in Richmond Hill: gaps where utility and A/C lines enter the foundation, worn garage-door bottom seals, weepers and foundation cracks, dryer and bathroom vents with stuck flaps, and soffit or fascia gaps at the roofline. A house mouse needs about 6 mm — the width of a dime. Mapping and sealing every one of them is part of every Sani IQ mice job in Richmond Hill.
Why don't you seal the entry points on the first visit?
Because sealing first traps mice inside — they die in wall voids and you get the smell for weeks. Our exit-first protocol treats on day one with exit routes open so mice leave and die outside, then we return in about three weeks to verify the knockdown and seal. Sealing is included; it's the sequence that matters.
Will the mice leave on their own once it gets cold or warms up again?
No. Mice move in for warmth and food in October–November and, once established, a house is better than outdoors in every season. A population that has nested inside grows through winter — a female can have 5–10 litters a year. Waiting makes it a bigger job, not a smaller one.

On the Oak Ridges Moraine, Nature Is Next Door — Literally
Richmond Hill's north half sits on the Oak Ridges Moraine — kettle lakes, wetlands and protected green space woven between subdivisions. It's why the town is beautiful, and it's why Oak Ridges and Jefferson homes see mosquito pressure, wildlife traffic and wasp activity that southern neighbours don't. Wilcox Lake and the wetland pockets breed mosquitoes all season; the forest tracts run squirrels and raccoons straight to rooflines.
South of Elgin Mills, the profile shifts: Mill Pond and the older core carry century-home mice and carpenter ants, while the Yonge corridor's condos and the newer phases toward Bayview share the tower and new-build patterns of the rest of York Region.
Exterior perimeter treatment — the backbone of every Sani IQ Protect visit.
What Richmond Hill Calls Us For

Frequently Asked Questions
How much does pest control cost in Richmond Hill?
Sani IQ bills every visit after it's done — no monthly fees. Mice inside in Richmond Hill? The Sani IQ Rodent Program is $445 at the first visit, then $150 a quarter, 12-month warranty. Want the whole house covered? Sani IQ Protect is $249 a visit, four visits a year, rodent prevention included. Mice and insects together? Protect Plus is $249 a visit (six visits). Base prices cover homes up to 2,000 sq ft. Bed bugs, German cockroaches, wildlife and rats are quoted after an inspection.
Why are mosquitoes so bad in Oak Ridges?
The moraine. Kettle lakes, wetlands and shaded forest pockets are continuous breeding habitat, and no amount of dumping birdbaths fixes what the landscape provides. Barrier treatments (monthly through the season on Protect Elite) knock pressure down for weeks; Protect Elite includes the whole season.
We hear scratching in the attic near the moraine — what now?
Almost certainly squirrels or raccoons off the forest tracts. We remove the animal humanely, seal the entry point and screen the vents — removal without exclusion just books the next tenant.
Do you cover Mill Pond and the older core?
Yes — and its century homes are Richmond Hill's mouse and carpenter-ant core. Exclusion-first treatment ends the every-winter cycle.
Are treatments safe for kids and pets?
Yes — reduced-risk, Health Canada–registered products, safe once dry, fully explained before treatment.
