Why North York’s mix of older homes and mid-rise apartments both attract mice, and what to do about it.
North York’s housing stock is genuinely varied — leafy, decades-old neighbourhoods sit close to dense clusters of mid-rise and high-rise apartment buildings, and mice find opportunity in both. Whether it’s a gap around an aging foundation or a shared wall in a multi-unit building, the pattern is the same: mice are looking for warmth, food, and a way in, and North York offers plenty of both housing types where they can find it.
Why North York Homes Are Vulnerable
Older, established homes in North York have had decades for small gaps to develop around foundations, utility lines, and window frames — exactly the kind of opening a mouse needs, which is as small as a pencil’s width. Meanwhile, North York’s many mid-rise and high-rise apartment buildings present a different risk: mice can travel between units through shared plumbing chases and wall voids, meaning a problem in one unit isn’t necessarily contained to that unit alone.
Signs of a Mouse Problem
- Droppings — small, dark, pellet-shaped, often found near food storage or along walls
- Gnaw marks — on wires, wood, or food packaging
- Scratching sounds — typically at night, light and quick
- A musky odour — noticeable in areas with heavier activity
Prevention Tips for North York Homeowners
- Seal visible gaps around foundations, utility lines, and window frames
- Store food, including pet food, in sealed containers
- Keep basements and storage areas decluttered so activity is easier to spot early
- In apartment buildings, report early signs to property management promptly
When to Call a Professional
Recurring droppings, activity in more than one room, or a mouse problem that persists despite basic prevention steps are all signs it’s worth a professional inspection — particularly in apartment or condo settings, where the source may not be confined to your own unit.

Frequently Asked Questions
North York’s mix of older established neighbourhoods and dense mid-rise apartment buildings both offer mice easy entry points — aging foundations in older homes, and shared walls or utility chases in apartment buildings, which let mice travel between units.
Small, dark, pellet-shaped droppings near food storage or along walls, gnaw marks on wires or wood, and light scratching sounds at night are the most common early signs of a mouse infestation.
Yes. Mice can travel through small gaps around shared plumbing and electrical chases, which means a mouse problem in a multi-unit building often needs treatment coordinated across more than one unit to fully resolve.
Activity typically increases in September and October as outdoor temperatures drop and mice look for warm indoor shelter for the winter.
