About Ajax, Ontario

Ajax is one of Durham Region’s fastest-growing communities, stretching from the Lake Ontario waterfront in the south to new residential developments along Taunton Road and Audley Road in the north. The town is home to a mix of established neighbourhoods like Riverside and Pickering Village, newer subdivisions in Salem and Westney Heights, and a growing commercial corridor along Bayly Street and Highway 401.

What makes Ajax unique from a mosquito standpoint is its geography. The Duffins Creek and Carruthers Creek systems run the full length of the town from north to south, and the Lake Ontario shoreline adds additional waterfront pressure along the south end. Parks like Rotary Park, Ajax Waterfront Park, and the Duffins Creek Trail are beloved by residents but also sit adjacent to some of the heaviest mosquito breeding zones in Durham Region.

Homes in Ajax range from compact townhouses near the GO Station to large detached properties in the newer north end communities. Regardless of property size or location, mosquito pressure is a seasonal reality for most Ajax residents from late May through early October. That is exactly why professional barrier treatment and seasonal programs are in high demand across the town every summer.
