Markham's Pests Track Its Housing Eras
Markham layers four decades of building booms, and each one has its own pest profile. The mature streets of Old Markham Village, Unionville and Thornhill carry the carpenter ants and winter mice that come with big trees and settled foundations. The 80s–2000s subdivisions of Milliken and Berczy sit in the middle. And the newer phases of Cornell, Wismer and Greensborough take displaced field mice with every round of grading toward the north-east.
The Rouge River system and its tributaries thread the whole city, moving rodents and wildlife between green space and rooflines — and Markham's dense townhome and condo blocks add the shared-wall dynamics that let German cockroaches move unit to unit, a problem we treat with the honesty it needs.
On-site at a Markham residential service call — same trucks, same licensed crew, every visit.
What Markham Calls Us For
German cockroaches in townhome and condo clusters — treated properly, with straight talk about when neighbouring units or the complex need to be involved. Mice across every housing era from October onward. Wasp and hornet nests in Unionville's mature eaves and Cornell's new fence lines alike. Carpenter ants in the older wards. And ants across interlock and patios every summer.
Same-day service is available across Markham most weekdays.
What It Costs in Markham
Homes in Markham 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 Markham?
Sani IQ bills every visit after it's done — no monthly fees. Mice inside in Markham? 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.
Our Markham townhome complex has roaches — can one unit be treated?
We can treat your unit properly, and we'll tell you honestly whether it will hold: in attached housing, German cockroaches travel through shared walls and utility runs, so lasting results usually need the neighbouring units addressed. We document everything for property management.
Why does my new Cornell or Wismer home have mice?
Each construction phase displaces the field rodents on that land, and new builds are rarely sealed to pest standard. One exclusion visit — finding and sealing entries — beats years of bait.
Do you serve Unionville and Old Markham Village?
Yes — and their mature trees and older framing make them Markham's carpenter-ant core. Nest-targeted carpenter ant treatment is covered on Sani IQ Protect Plus ($249 a visit, six visits a year).
Is Sani IQ licensed and insured?
Yes — licensed under the Ontario Pesticides Act, MECP-registered, $5M liability. Every technician is an employee, never a subcontractor.
