City officials and University of Saskatchewan experts report that mosquito and tick populations are rising across Saskatoon [1, 2].
The surge in insect activity increases the risk of pest-borne irritations and potential health concerns for residents spending time outdoors during the summer months.
Officials said that more rain and standing water have created favorable breeding conditions for these insects [1, 4]. This environmental shift has led to a higher density of pests throughout the region during the 2025-2026 season [2, 3].
Reports on the mosquito population show varying levels of activity. Some reports from May 2026 indicated the season was off to a slow start due to a late spring [4]. However, other reports highlighted a significant spike in the population [3].
Experts said a later-starting spring may be contributing to a sudden surge as temperatures finally warm, coinciding with the abundance of standing water [1, 4]. The University of Saskatchewan has noted that the region is enduring a super-abundant year for ticks [2].
City officials are monitoring the situation as the weather continues to shift. The combination of moisture, and warming temperatures remains the primary driver for the current insect levels [1, 4].
“Mosquito and tick populations are rising in Saskatoon”
The intersection of abnormal precipitation and fluctuating spring temperatures is altering the local ecological balance in Saskatchewan. A 'super-abundant' tick year combined with mosquito spikes suggests that environmental factors are overriding typical seasonal patterns, potentially extending the window of exposure for residents to insect-borne pathogens.
