Between May 15, 2019 and September 30, 2019, municipalities within the Region of Waterloo will be conducting a larviciding program under the authority of the Region of Waterloo Medical Officer of Health to prevent the development of mosquito larvae into vectors of West Nile Virus. Altosid Pellets (methoprene, PCP #21809) or VectoLex WSP pouches (Bacillus sphaericus, PCP #28009) will be placed into catch basins of storm drains within the Region. The granular formulation of the larvicide VectoLex CG (Bacillus sphaericus, PCP #28008), will be applied to sewage lagoons, where larvae are present. The liquid formulation of the larvicide VectoBac 1200L (B.t.i., PCP #21062) or VectoBac 200G (B.t.i., PCP #18158, granular) will be applied to standing water throughout the Region, where larvae are present.
