The City of Selkirk has launched its seasonal mosquito control efforts to manage the local insect population as warmer weather arrives. This year, the city started its targeted larviciding program during the first week of May to treat standing water before larvae can mature into biting adults.
According to the City of Selkirk, this proactive approach is the most effective and environmentally acceptable way to control mosquitoes. The program’s success has meant that the city has not needed to use adult mosquito fogging for several years. All materials used during these treatments comply with federal regulations set by the Government of Canada under the Pest Control Products Act.
The city also monitors for all mosquito species, including those capable of carrying West Nile virus, with the help of funding provided by the Province of Manitoba. Selkirk has been part of the provincial surveillance network for several years, with positive mosquito pools identified in 2008, 2021, and 2022. This ongoing monitoring remains a priority, as Manitoba recorded 3 confirmed human cases of West Nile virus, 148 positive mosquito pools, and 28 positive birds across the province during the 2025 season.
