The City of Dawson announced the launch of its 2026 Mosquito Control Program on April 8, 2026, marking the start of efforts to manage seasonal insect populations throughout the community.
The annual initiative aims to reduce the number of adult mosquitoes by targeting larvae in their early stages. Duka Environmental Services Ltd., which has managed mosquito control for communities across the territory since 1986, will oversee the program. The effort is designed to limit annoyance for local residents, workers, and visitors, as well as lower the possibility of mosquito-borne diseases.
Work for the program typically occurs between April and August. During this time, crews apply a biological larvicide known as VectoBac 200G to areas of standing water, such as ponds and swamps, where mosquitoes often breed. According to the Yukon Government, these treatments are conducted both by hand and from the air.
Residents looking for the most current information regarding the implementation of the program in Dawson City can check the community notices posted on the municipal website. The program is part of a territory-wide effort to address seasonal fluctuations in mosquito numbers, which can vary significantly depending on local weather conditions.
