Why Markham Residents Trust BHT for Backyard Mosquito Control
Markham sits within York Region, one of the most closely monitored areas in Ontario for West Nile virus activity. Every summer, York Region Public Health sets up and monitors mosquito traps across the region, with positive results recorded near Markham intersections including Kennedy Road and 16th Avenue, Warden Avenue and Highway 7, and Bayview Avenue and John Street. While the region treats public catch basins and road-side ditches, private backyards and commercial properties are not covered by the public program. That is where BHT Mosquito Control comes in.
Our team brings professional-grade solutions directly to your property, giving Markham residents and businesses the level of protection that public programs simply do not provide.

Why Markham properties need professional treatment
Markham is one of the fastest-growing cities in Ontario, with a mix of new residential developments, mature tree canopy, and green spaces throughout York Region. This combination of dense vegetation, retention ponds, and suburban landscaping creates ideal conditions for mosquito breeding from late May through early October. Every summer, York Region Public Health records West Nile virus activity in mosquito traps across the city, with positive detections reported near major Markham intersections. While the Region treats public roadside catch basins, private residential and commercial properties are not covered, leaving homeowners and businesses responsible for their own backyard protection.

Frequently Asked Questions About Mosquito Control in Markham
When is mosquito season in Markham, Ontario?
Mosquito season in Markham typically runs from late May through early October. Peak activity occurs in July and August, which also coincides with York Region’s annual West Nile virus surveillance period. Starting treatments in late spring gives you the best protection through the entire season.
How long does a mosquito barrier treatment last?
A single barrier spray treatment typically provides protection for 3 to 4 weeks. For full-season coverage, we recommend our seasonal program with scheduled visits every 21 days to maintain a consistent mosquito-free zone around your property.
Are your treatments safe for children and pets?
Yes. We use Health Canada-approved products that are safe for families and pets once the treated areas are dry, which usually takes 30 to 60 minutes after application. Our technicians always follow Ontario pesticide regulations and label directions on every visit.
Do you treat commercial properties in Markham?
Absolutely. We service restaurants with patios, office parks, event venues, condominium complexes, and large commercial properties throughout Markham and York Region. Our commercial program is tailored to minimize disruption while delivering consistent, professional results.
Can mosquito control help reduce West Nile virus risk?
Professional barrier treatments significantly reduce mosquito populations on your property, lowering your family’s exposure to bites and the viruses mosquitoes can carry. York Region Public Health recommends eliminating standing water and using protective measures as part of a complete prevention approach. Our treatments complement those public health recommendations by targeting mosquitoes directly on your property.
How quickly can you come to my property in Markham?
We offer same-day and next-day appointments across Markham. Contact us and we will schedule a visit at your earliest convenience.
Does rain affect my mosquito treatment?
Once our barrier spray has dried, it is rain resistant. We recommend allowing at least one hour after application before any rainfall or irrigation for the treatment to fully set. If significant rain occurs shortly after treatment, contact us and we will assess whether a follow-up visit is needed.
BHT Mosquito Control serves all of Markham and York Region. Same-day appointments available.
