Mosquito Counts
How Weather Impacts Mosquito Activity
You can generally expect a bump in mosquitos about one to two weeks after a rain event. Temperature also plays a role in mosquito development: the hotter it is outside, the faster mosquitos develop.
Weekly Update
Only female mosquitos bite, as they need blood to develop their eggs. Among the female mosquitos we monitor, we highlight catches from the Culex genus—these mosquitos have the greatest risk of transmitting West Nile virus in Canada.
For up-to-date information on West Nile virus activity, please visit the Province of Saskatchewan's West Nile virus surveillance results.
