What Vaughan's Property Standards By-law 231-2011 requires of owners
| Section or source | What it requires | What it means for mice |
|---|---|---|
| Section 5.1(b) | Every yard must be kept clean and free from rodents, vermin, insect pests and other pests and from any condition that may encourage their infestation or harbouring. | The yard duty covers the conditions that harbour pests. |
| Exterior openings | Openings in exterior walls not protected by a door or window must be screened with wire mesh, a metal grill or otherwise suitably protected to prevent the entry of vermin, rodents, insects or other pests. | Wire mesh over openings is the by-law's own answer, which matches covering vents and weep holes with breathable mesh. |

How AstraHive Pest Control gets rid of mice in Thornhill
- 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.

| What the guides say | Guide |
|---|---|
| Every inspection considers where mice were seen and when, where droppings and urine or odour occur, where gnawing and nesting material are found, where travel routes are likely, and where entry points are located. That full picture, not a single sighting, is what an effective treatment plan is built on. | Why Mice Keep Coming Back Every Year (It's Rarely the Same Mouse) |
| Handling a trap barehanded transfers your scent directly onto the plastic or wood. Rats have a strong sense of smell and will often approach a human-scented trap with excessive caution, or avoid it completely and just walk around it. | Why Your Rat Traps Aren't Catching Anything: 5 Real Reasons (Ontario Guide) |
| Mice are thigmotaxic, meaning they navigate by keeping their whiskers and fur in contact with a vertical surface. A trap sitting in the middle of a room, even a few inches off the baseboard, gets ignored because it's outside the animal's actual travel path. | Why Your Mouse Traps Aren't Working: Victor Snap Trap Placement Mistakes (Ontario Guide) |
| House mice have large ears and range from light brown to dark grey with a lighter belly. | Health Canada: rats and mice |
| Deer mice are the most common carrier of hantavirus. | Health Canada: rats and mice |
| Dead rodents should be double-bagged in plastic and put in a secured garbage container. | Health Canada: rats and mice |
| A mouse will tug at the material to pull it back to a nest site, and that tugging motion triggers the trap just as reliably as feeding does. This works especially well on mice that have already been ignoring food-based bait for several nights in a row. | Best Bait for a Mouse Trap in Ontario (It's Not Cheese) |
Older homes and shared walls in Thornhill
Thornhill is part of Vaughan, so these are Vaughan figures. 8% of homes in Vaughan were built before 1981 and 24% 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.
