Rat removal in Richmond Hill means locating where the rats live outside, usually a burrow under a deck, shed or patio slab, treating it, and sealing the openings into the house. Mice control is a smaller job: trap the mice that are in, then close the small gaps they used. Budget $300 to $600 and up for rats and $200 to $500 for mice, with a free inspection first and the price fixed before anything starts. Call or use the form for same-day booking anywhere in the city. This page is the rodent detail behind our main page on pest control in Richmond Hill; how each animal behaves is covered in our region-wide mouse control and rat control guides.
What rat removal involves on a Richmond Hill property
A rat removal job has five parts, and skipping any one of them is why the rats come back.
- Map the colony. We walk the lot line, the foundation, the deck, the shed and the bin area looking for burrow openings, runs flattened into the grass, and gnawing at the base of doors. The first visit tells us whether there is one burrow or a network.
- Cut the food. Open compost, bird seed on the ground, a green bin left at the side of the house, pet food on the porch. Nothing else works while the rats are being fed.
- Treat the burrows. Bait goes only into locked, tamper-resistant stations placed along the runs, never loose in a hole. Snap traps work inside the garage and basement.
- Seal and collapse. Once activity drops, active burrows are collapsed and the foundation openings are closed with hardware cloth, sheet metal or mortar. Foam alone does not stop a rat.
- Check it held. Follow-up visits confirm the stations have gone quiet and no new holes have opened.
Most residential rat jobs need two or three visits over a few weeks. A single visit with a bait box and no sealing is a rental fee, not a removal.
Mice control in the north end: Oak Ridges, Lake Wilcox and Jefferson
Richmond Hill's north end sits on the Oak Ridges Moraine. Lake Wilcox, in the Oak Ridges community, is the largest kettle lake on the Moraine and the headwaters of the East Humber River (City of Richmond Hill, Lake Wilcox). The streets around it, and the newer subdivisions in Jefferson and Oak Ridges, back onto woodlots, wetland and open moraine land.
That landscape is mouse habitat. When the nights cool in September and October, field mice and white-footed mice move from the edges into whatever is warm, and a house at the end of a crescent backing onto the woods is the first warm thing they meet. On these lots we put most of the effort into the envelope: garage door corners, the gap under the front porch slab, utility penetrations, and the soffit returns where the roof meets a lower wall.
Further south, in Richvale, Crosby, Mill Pond and the streets off Bayview, the pressure is lower but steady. The entries are the usual suburban ones: weep vents, a worn garage seal, a dryer vent flap that no longer closes.
Rats along the Yonge corridor
Rats in Richmond Hill concentrate where food and ground disturbance meet. The Yonge Street corridor has both. Tower sites are dug down for underground parking, which breaks up any burrow on or near the lot, and finished buildings put ground-floor restaurants, garbage rooms and loading areas side by side.
If you own a house on a side street near a construction site and suddenly have rats for the first time, that is the usual story. The fix is the same as anywhere: cut the food on your lot, treat the burrows, seal the foundation. If you are in a condo and rats are coming from the garbage room or the parkade, that is the corporation's problem to solve, and York Region Public Health says plainly that condominium boards have a legal responsibility to maintain their property (York Region, preventing rats and rodents).
What Richmond Hill's by-laws expect from your yard
Richmond Hill passed a new Property Standards By-law, No. 62-24, and a new Clean Neighbourhoods By-law, No. 63-24, on June 5, 2024. Both bear directly on rodents.
The Property Standards By-law 62-24 requires every dwelling unit to be kept free of pests, including rodents, and of any condition that might harbour them. It also requires openings in a building with dwelling units, from vents and pipe holes to cracks and floor drains, to be screened or sealed against pests.
The Clean Neighbourhoods By-law 63-24 is the more practical one for a rat problem:
- Compost must be in a composter in the rear yard, with a securely fitting lid, at least 0.5 metres from the property line. Only fruit, vegetables, eggshells, tea and coffee grounds go in. No meat, fish, bones, dairy, oil or fat.
- Garbage containers need a tightly fitting lid so they do not attract rodents.
- Bird feeders must be self-supporting and at least 1.2 metres above grade, and spilled seed on the ground has to be cleaned up promptly.
Most backyard rat problems in Richmond Hill start at the compost or under the bird feeder, and the by-law already tells you how to fix both.
If a neighbouring property is feeding rats onto yours, call the City's by-law office on 905-771-0198 or email Bylaw@richmondhill.ca (City of Richmond Hill, property standards). Officers can issue an order to fix the conditions.
Green bin night and garbage week
Richmond Hill collects the green bin every week and garbage every other week. Carts go out no earlier than 6 p.m. the night before and must be back off the curb by 9 p.m. on collection day, and the City suggests storing the green bin inside a garage or shed between pickups (City of Richmond Hill, garbage and recycling).
Those rules are pest control. A green bin left overnight by the side door every night of the week is a feeding station, and two weeks of garbage in bags on a garage floor is the reason a rat chews the bottom corner of the garage door.
What rat removal and mice control cost in Richmond Hill
Rat removal in Richmond Hill runs $300 to $600 and up; mice control runs $200 to $500. The free inspection sets the final number.
| Richmond Hill job | Typical range |
|---|---|
| Yonge corridor condo unit, mice | $200 to $300 |
| Detached or townhouse, mice, trapping plus sealing | $300 to $500 |
| Rats, one or two burrows, foundation sealing | $300 to $450 |
| Rats, several burrows or rats already inside | $450 to $600 and up |
What pushes a Richmond Hill job up: a large Oak Ridges or Bayview Hill lot with a long foundation to seal, a deck built low to the ground that has to be opened up to reach the burrows, and attic activity in a two-storey. The cost guide for York Region covers every pest.
Can you handle it yourself?
Mice, sometimes. If you have seen one mouse and found a few droppings in one spot, a handful of snap traps along the wall and a weekend sealing the garage door corners with steel mesh may be all it takes.
Rats, rarely. The bait sold to homeowners is a narrower set of products than commercial-class bait, which Health Canada restricts to certified professionals, and even that has to go in a tamper-proof station wherever kids or pets could get at it (Health Canada, rats and mice). More to the point, bait does not collapse a burrow or close a hole in the foundation. If you are seeing burrows, droppings the size of a bean, or a rat in daylight, book the inspection.
Do not pour bait down a burrow or scatter it under a deck. A poisoned rat can die in a wall void or be eaten by a dog or a hawk, and loose rodenticide is exactly what the Health Canada rules are written to prevent.
Tenants and condo owners
If you rent, rodents are your landlord's to fix. Ontario's Residential Tenancies Act makes the landlord responsible for keeping the unit in good repair and fit for habitation, and the City's property standards page says it in plain words: upkeep is the landlord's job. Write to the landlord, list what you have seen and when, keep a copy, and allow access for treatment. Condo owners should report to management, since rats in common areas are the corporation's job.
Common questions
How much does rat removal cost in Richmond Hill?
Most rat removal jobs in Richmond Hill run $300 to $600 and up. One or two burrows with some foundation sealing sits near the low end; several burrows, a low deck that has to be opened, or rats already inside the house push it higher.
Why am I suddenly getting rats near Yonge Street?
Construction is the usual reason. Digging for tower foundations and underground parking breaks up existing burrows and pushes rats onto the nearby side streets, where compost, bird seed and bins give them a reason to stay.
Do the Oak Ridges and Lake Wilcox homes really get more mice?
Yes. That end of the city sits on the Oak Ridges Moraine, with woodland and wetland behind many lots, so field mice are living close by all summer and move toward houses as the nights cool.
Is my compost causing the rats?
It often is. Richmond Hill's Clean Neighbourhoods By-law requires a lidded composter in the rear yard, set back from the property line, with no meat, fish, bones, dairy or fat. A composter that breaks those rules is one of the usual rat sources we turn up.
Can I report a neighbour whose yard has rats?
Yes. Phone the City's by-law office on 905-771-0198 or email Bylaw@richmondhill.ca. An enforcement officer can order the owner to correct the conditions.
How long does rat removal take?
Usually two or three visits over a few weeks: the first to map and treat, then follow-ups to confirm the stations have gone quiet and to seal and collapse the burrows. The two-month guarantee covers one free re-treatment if activity continues.
