 Larviciding is a low risk and effective measure for the control of West Nile virus
 Methoprene is the larvicide that is used. The slow-release pellet formulation interferes with the mosquito life cycle, preventing the mosquito larva from reaching maturity. It is not sprayed. The products have been approved by both the provincial and federal governments and are considered low risk for humans, pets and the environment when applied in accordance with label instructions
 Larvicide will be placed into catch basins by the Ministry of the Environment licensed applicator, the Canadian Centre for Mosquito Management Inc.  Staff will use scooters in residential areas and vehicles on busier roads to treat the catch basins
 In 2006, there were three human cases, 10 birds and 10 mosquito pools (or batches) that tested positive for the virus in York Region. The Ministry of Health and Long-Term Care attributed two deaths in the province last year to West Nile virus illness
