City of Hamilton to begin water treatment after concerns over West Nile Virus development

The City of Hamilton will be treating surface water with larvicide in the coming weeks in order to prevent the West Nile Virus from developing within the city boundaries.

The City says their tests on immature mosquitoes led to concerns that larval could develop into vectors of West Nile Virus.

Application of larvicide is expected to commence in early June and continue through October 2021.

The larvicides VectoBac 200G, VectoBac 1200L, and VectoLex CG will be applied to identified standing surface water located on public property, according to the City, which adds that the application will be carried out under permit from the Ontario Ministry of Environment, Conservation and Parks.

The control products will also be applied by licensed applicators or trained technicians of Pestalto Environmental Health Services Inc. under contract with the City of Hamilton.
