West Nile Virus Mosquito Management 

West Nile Virus (WNV) is an infection of primarily birds, spread by mosquitoes. Mosquitoes pick up the virus by biting an infected bird, and the virus is then transmitted to humans through the bite of an infected mosquito.  It was detected in BC and Metro Vancouver in 2009 for the first time.

Metro Vancouver is continuing to take steps to minimize the risk to residents, including working with the Province, Health Authorities, and municipalities to identify, monitor and treat significant mosquito areas using ecologically sensitive larvicides. The best protection from West Nile Virus is to avoid being bitten by mosquitoes, by removing standing water and by using personal protection.

On lands that it owns, Metro Vancouver controls populations of mosquitoes that may carry the virus. These lands include wastewater treatment plants, waste transfer stations, regional parks and greenways, housing facilities and Electoral Area A public lands.
