Pest control in Richmond Hill

Richmond Hill has older streets lined with big trees, newer homes that back onto green space, and tall condos along the Yonge Street corridor. Each one brings different pests to the door.

What pests are common in Richmond Hill

Mice in fall. Homes near ravines, parks and the Oak Ridges Moraine are close to fields and woodland. When nights turn cold, mice look for a warm spot, and a small gap near a foundation or pipe is enough.

Wasps in summer. Mature trees, eaves and garden sheds give wasps plenty of places to build. Nests grow through July, August and September. See wasp nest removal.

Ants in spring. Ants come inside looking for food and water as the ground warms. Our ant control service starts by finding where they come from.

Bed bugs and cockroaches in shared buildings. These two spread between units, so condos and apartments need a plan for the whole floor, not only one suite.

Homes in Richmond Hill and what each tends to see

• Mature detached homes, such as around Mill Pond and Bayview Hill. Older trim, crawl spaces and tree limbs near the roof can give mice and wasps an easy way in.
• Homes that back onto green space. Expect more wildlife pressure: mice in fall, wasps in summer.
• Condo towers near Yonge Street and Langstaff. Shared walls and pipes make bed bugs and cockroaches a building-wide matter.

Renting in Richmond Hill: who to speak to first

York Region Public Health’s advice on rodents is clear about the first step. If you rent an apartment, speak to your landlord, building owner or property manager. If you own a condo, tell the condo board and property management. Owners of single-family homes can hire a private pest control company.

For bed bugs, the Region says to confirm the problem with a professional, and to choose products made for bed bugs if you use any. If you still see many bugs after two weeks of treatment, call a professional pest control service. Bed bugs can also move between apartments through pipes and wiring, so sealing openings helps.

In Ontario, landlords must keep rental units in a good state of repair under the Residential Tenancies Act. Tell your landlord in writing as soon as you notice a pest problem.

Simple steps before you call

• Seal gaps around pipes and foundations with steel wool and caulk.
• Keep firewood and bins off the ground and away from the house.
• Store dry food and pet food in metal or glass containers.

If mice are already inside, see rodent control rather than trying to handle droppings or nests alone.

Why homes near green space get mice

Mice do not need much. A gap about the size of a pencil is enough. Homes beside ravines, creeks and wooded lots sit close to where mice already live, so the trip to your garage or basement is short.

Fall is the main push. Cold nights send mice looking for shelter and food. They tend to use:

• Gaps where pipes, vents or cables enter the house
• Weep holes and cracks at the foundation
• Garage doors that do not seal at the bottom
• Dryer vents and chimney caps without screens

Trees and shrubs touching the house act as a bridge. Trim them back so there is clear space between branches and the roofline.

When wasps peak

Wasp colonies start small in spring and grow through summer. By August and September a nest can hold many workers, and they become more defensive. That is when most stings and calls happen. If you find a nest, keep children and pets away, and do not block the entrance.
