The Culex tarsalis is the primary transmitter of West Nile virus and Western Equine Encephalitis. The species is predominantly located south of the parkland area. The Aedes vexans species is the most common nuisance mosquito pest for humans. It is common throughout the prairie regions from grasslands to forest.
Mosquito control is best managed through an integrated Pest Management strategy with larviciding and fogging being part of the combination of treatments.
