How BuzzSkito Mosquito Control Works
Free Property Assessment
We evaluate your property — identifying water features, dense vegetation, and mosquito pressure zones specific to your area.
Professional Barrier Spray
Our licensed technician applies Health Canada-approved formula to all vegetation, shrub interiors, leaf undersides, and fence lines using a precision backpack sprayer.
30-Day Protection Guarantee
The barrier kills mosquitoes on contact and repels new ones for up to 30 days. If pests return within the window, we re-treat at no cost.
Why Mosquito Pressure Is High in Markham
Markham's geography makes it one of the GTA's most active mosquito municipalities. The city straddles the Rouge River system — one of Canada's largest urban river ecosystems — with wetland pockets and forested floodplain running from Cathedraltown in the north down through Cornell to the Rouge National Urban Park boundary. Milner Creek bisects central Markham, winding through Berczy Village and Wismer communities where maturing subdivision landscaping traps moisture along fence lines and garden borders.
In historic Markham Village, the Don River headwater tributaries and Swan Lake sustain mosquito populations from early May, while Toogood Pond in Unionville draws mosquitoes into the creek valley park system throughout the peak season. For Markham homeowners, the combination of a broad river system, multiple pond features, and a dense mature tree canopy creates conditions that reward early, consistent barrier spray treatment.
Markham Neighbourhoods We Serve
BuzzSkito provides mosquito control across all Markham communities, including:
Our Markham Mosquito Treatment Process
- Yard assessment — We identify creek proximity, tree canopy, standing water, and conditions specific to your Markham lot.
- Vegetation barrier spray — Full treatment of shrubs, hedges, fence lines, ornamental grasses, and tree understorey.
- 28-day residual protection — Health Canada–approved formula continues working between visits; safe for kids and pets after a 30-minute dry time.
- Seasonal program — Five applications May through September, timed to match Markham's Rouge River and creek-driven emergence patterns.
Also Providing Tick Control in Markham
Markham's proximity to the Rouge National Urban Park and extensive forest edges along the Rouge River corridor create significant blacklegged tick exposure for homeowners in Cornell and Cathedraltown. Ask about our Markham tick spray service — combining both treatments gives your property complete year-round protection.

Why Professional Treatment Outperforms DIY
Citronella candles, essential oil sprays, and consumer foggers provide temporary relief in a small radius — typically 30 minutes to 2 hours in the immediate area of use. Professional barrier spray treats every resting surface on your entire property, creating a residual barrier that kills mosquitoes on contact for up to 30 days. The difference is coverage and duration: DIY products address symptoms; barrier spray addresses the source of activity on your lot.

When to Start Treatment
In the GTA, mosquito season typically runs from late April through September. The best time to book your first treatment is early-to-mid May, before populations peak. Starting early establishes a protective barrier before breeding cycles accelerate in June and July. Read our full seasonal timing guide.

FAQ – Mosquito Control in Markham
How much does mosquito control cost in Markham?
BuzzSkito mosquito control in Markham starts from $99 per application. Properties near Rouge National Urban Park, Swan Lake, or any ravine corridor typically benefit most from the full seasonal package for continuous protection. No contracts. Call (289) 216-5030 for a free Markham quote.
Why do Unionville backyards have such a bad mosquito problem?
Unionville's Toogood Pond and the creek system flowing through the heritage village core create a natural mosquito nursery that is active from May through August. The mature tree canopy along Main Street Unionville and the adjacent park system retains moisture and provides ideal resting habitat for adult mosquitoes throughout the day. Homes backing onto the pond or within a few blocks of the creek typically benefit most from early-season barrier spray.
Does the Rouge National Urban Park affect mosquito pressure in Markham?
Significantly. Cornell and Cathedraltown are the Markham neighbourhoods closest to the Rouge National Urban Park boundary, and both experience elevated mosquito pressure due to their proximity to the Rouge River system and its associated wetlands. Milner Creek, which runs through central Markham, also contributes to breeding habitat for properties in Berczy Village and Wismer. Professional barrier spray on your property creates a treated buffer between these natural areas and your yard.
Is Swan Lake in Markham Village a source of mosquitoes?
Swan Lake and the Don River headwater tributaries running through Markham Village and Old Markham are active mosquito breeding sources through the early and mid season. The shallow margins of Swan Lake in particular warm quickly in spring, producing an early surge of adult mosquitoes before many homeowners have scheduled their first treatment. We recommend Markham Village homeowners book their first visit in early May.
