Mice Season in Newmarket
Mice Control in Newmarket
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.
Newmarket pairs century homes around historic Main Street and the Holland River with newer subdivisions in Stonehaven, Glenway and Summerhill — two very different ways mice get in. Older homes have settled foundations and gaps around aged service lines; newer builds have construction voids and garage seals that haven't aged well. Sani IQ finds and seals the entries either way, instead of just leaving bait behind.
Where we find them getting in around Newmarket
- Droppings under the kitchen sink, in the garage, or along basement walls
- Scratching or scurrying in walls and ceilings after dark
- Gnaw marks on food packaging, wiring or wood trim
- A musky ammonia smell in pantries, closets or the utility room
- Activity that returns each fall as the weather cools
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 Newmarket Homes
Our inspections in Newmarket 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 Newmarket — common questions
My older Newmarket home keeps getting mice — why?
Century and mid-century homes near Main Street and the Holland River have settled foundations and gaps around aged plumbing and wiring. We seal those entry points, which is the step most companies skip.
Do you serve the newer subdivisions too?
Yes — Stonehaven, Glenway, Summerhill and the rest of Newmarket. New builds have their own gaps around garages and service penetrations, and we treat those too.
How do mice get into Newmarket homes?
The entries we find most in Newmarket: 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 Newmarket.
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.

Old Main Street, New Subdivisions — Newmarket Gets Both Kinds of Pests
Newmarket splits cleanly along its history. The heritage core around Main Street and Fairy Lake carries century homes on stone foundations — reliable winter mouse territory, with carpenter ants working the mature maples and older framing above. The East Holland River corridor and its trail system move rodents and wildlife right through the middle of town.
Around the edges, Stonehaven, Copper Hills and the newer phases toward the 404 behave like every growth corridor: displaced field mice after each construction phase, wasps colonizing new fence lines and play structures, and attics that squirrels find within a season or two of the sod going down.
Every completed visit is documented — you always know what was done and what comes next.
What Newmarket Calls Us For
Mice in both the century core and the new phases — different causes, same exclusion-first fix. Wasp and hornet nests from June to September — covered nest removal is included on every Sani IQ Protect plan. Carpenter ants in the mature streets around the core and Gorham-College area. Squirrels and raccoons along the Holland River corridor into attics — removed, sealed, screened. And ants across patios and interlock every summer.
Newmarket is on our daily Yonge Street corridor between Barrie and the GTA — same-day is usually available.
What It Costs in Newmarket
Homes in Newmarket are billed after each visit — no monthly fees. Sani IQ Protect is $249 a visit, four visits a year, for homes up to 2,000 sq ft. That covers quarterly service for common ants, household spiders, earwigs, centipedes, cluster flies, silverfish and wasps (covered nest removal included), an exterior barrier with eave and soffit treatment, free re-service between visits and a photo report after every visit — with rodent prevention included.
Mice inside? The Sani IQ Rodent Program ($445 at the first visit, then $150 a quarter) removes them in three weeks, seals how they got in and keeps the stations in all year with a 12-month warranty. Mice and insects together? Protect Plus ($249 a visit, six visits a year) covers both, with carpenter ants and 48-hour re-service. Bed bugs, German cockroaches, wildlife and rats are quoted after an inspection.

Frequently Asked Questions
How much does pest control cost in Newmarket?
Sani IQ bills every visit after it's done — no monthly fees. Mice inside in Newmarket? 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 does my Main Street–area home get mice every winter?
Heritage foundations. Stone and early-block foundations open gaps as they settle each season, and the older core is full of them. Sealing the entries — not endless bait — is what ends the annual cycle.
We back onto the Holland River trail — is that why we get wildlife?
Yes. The river corridor is a highway for squirrels and raccoons moving between green space and rooflines. We remove humanely, seal the entry and screen vents so the attic stays empty.
Do you cover Aurora and East Gwillimbury too?
Yes — the whole Yonge corridor is on our daily routes, from Bradford through Newmarket and Aurora toward Richmond Hill.
Are your treatments safe for kids and pets?
Yes — reduced-risk, Health Canada–registered products, safe once dry, explained by your technician before any treatment.
