Cockroaches Problems in Markham? Here's How We End Them.
Markham's dense townhouse rows in Cornell, Berczy and Milliken, its condo corridors along Highway 7, and its busy restaurant scene around Pacific Mall and Unionville give German cockroaches exactly what they need — warmth, moisture and shared walls that let one untreated kitchen re-seed a whole block. Sani IQ has a technician based in Markham and runs a gel-bait plus growth-regulator program that breaks the breeding cycle instead of just killing the roaches you see.

Our Process
How Sani IQ Handles Cockroaches in Markham
Species ID & inspection
German cockroaches need a completely different program than oriental or American roaches. We identify the species and locate harborages — warm motors, hinges, drains, wall voids.
Gel bait + IGR program
Targeted gel baits plus insect growth regulators break the breeding cycle instead of just killing the roaches you see. Safe for kitchens when applied by licensed techs.
Crack & crevice treatment
Residual treatment of harborages and travel routes — not a fog that scatters roaches deeper into the building.
Follow-up visits
Cockroach jobs include scheduled follow-ups until activity hits zero. We don't consider it done until you do.
