Mice in your Commerce Valley home or building?
Our licensed technicians start with an inspection and a clear plan for your property.
Call 905-925-8427How AstraHive Pest Control gets rid of mice in Commerce Valley
- Inspection. We check the foundation, penetrations, doors, roofline and interior for entry points and travel routes.
- Exterior sealing. Entry points are closed from the outside with steel wool or copper mesh locked in with sealant or foam, and hardware cloth for large gaps. We never seal interior gaps. Weep holes and vents get breathable mesh only (steel wool, copper mesh or excluder mesh), never sealant, foam or mortar, because the hollow wall needs them to release moisture and warm air.
- Interior trapping. We trap the mice inside, with tamper-resistant bait stations where bait is needed.
- Follow-up. We return to check traps and seals.
Products are Health Canada approved and applied according to the product label, and our technicians are licensed by the Ontario Ministry of the Environment, Conservation and Parks (MECP). Our mouse work is backed by a 90-day warranty.
Older homes and shared walls in Commerce Valley
Commerce Valley is part of Markham, so these are Markham figures. 19% of homes in Markham were built before 1981 and 28% are semi-detached, row or other attached homes. Older foundations and shared walls and roof lines give mice more gaps to use, which is why the inspection covers the foundation, penetrations and roofline.

More on mice for Commerce Valley homeowners
A mouse can squeeze through a crack as small as a dime, and a rat through a hole the size of a quarter. Health Canada: rats and mice
The best bait in the wrong spot catches nothing. The second-best bait placed directly in an active travel path along a wall, behind an appliance, or inside a cabinet where droppings are visible will consistently outperform premium bait set in the middle of an open floor. Best Bait for a Mouse Trap in Ontario (It's Not Cheese)
Most consumer electronic traps are sized and calibrated for house mice. A rat is heavier and longer, and it frequently doesn't trigger the plates correctly or doesn't make full contact across its body to complete a lethal shock. Do Electronic Mouse Traps Work? An Honest Ontario Pest Control Breakdown
The first line of defence against mice is eliminating easy entry points, since mice can squeeze through cracks as small as a dime. Interior gaps like baseboards or attic hatches aren't entry points at all, they're just travel routes a mouse uses once it's already inside, and sealing them only pushes the mouse to find another route through your walls without solving anything. Do Glue Traps Work for Mice? An Honest Ontario Pest Control Breakdown
Even if release distance weren't an issue, live traps have a second, unrelated limitation: they catch one mouse per set. A house mouse can enter through a gap as small as a dime, and once one gets in and finds food and shelter, breeding follows fast. Do Live Mouse Traps Actually Work? Release Distance, Population Math, and When They Fail
Traps and bait reduce the population that's already indoors. Finding and closing every entry point, with materials that actually hold up to gnawing, is the part of the job that actually ends a mouse problem, not the traps and not the bait. How Do Mice Get Into a House? The 6 Entry Points We Find on Every Ontario Inspection
Mice aren't created by cold weather, they're already living in fields, woodpiles, and green spaces around your property all year. As temperatures fall, the warmth and shelter inside a heated structure becomes dramatically more attractive than staying outside, so existing mice start actively searching for a way in.
