The City of Estevan has announced that low numbers of Culex tarsalis mosquitoes have been found in mosquito traps in the city and elsewhere in southern Saskatchewan.
Culex tarsalis is the mosquito that carries the west Nile virus.
No infected west Nile virus-positive mosquitoes have been found so far this year. The risk of transmission to humans is minimal to low, but is expected to rise in July.
Higher numbers of other mosquito species are being detected in areas that received rainfall over the past two weeks.
Local residents are urged to take precautions against mosquito bites.
They can protect themselves by covering up and wearing repellents or reducing the amount of time spent outdoors. Mosquitoes can be active at any time but are most active in the evening and throughout the night.
They can also wear light-coloured clothing, eliminating standing water, and ensuring screens for doors and windows are secure.
Regardless of the West Nile virus risk level for the area, people are asked to remember there is no such thing as being risk-free from West Nile. If people get bitten by an infected mosquito, they can contract West Nile or other mosquito-borne viruses.
Other mosquito species are being detected in higher numbers than normal in southern Saskatchewan. Thunderstorm activity in June flooded many low-lying areas, resulting in increased mosquito habitat. Numbers will continue to increase in those areas that received significant rainfall.
More information on West Nile virus risk levels and prevention can be found on the provincial government’s website.Â
