From May 13 to October 31, 2024, Halton Region Public Health will be conducting a mosquito larviciding program under the direction of Dr. Deepika Lobo, Halton Region Medical Officer of Health, to reduce the incidence of West Nile virus (WNV) in the City of Burlington, the Town of Halton Hills, the Town of Milton and the Town of Oakville.

Larviciding in standing water

The biological larvicide, VectoBac 200G (PCP# 18158, granular) or VectoBac 1200L (PCP# 21062, liquid), will be applied to affected standing water on public lands in urban areas, where monitoring indicates that mosquito larvae are present. Signs will be posted at each location indicating when and where the larvicide has been applied.

Larviciding in catch basins
