Vector Control

This is a grant-funded program that allows the collection and testing of dead birds and mosquitoes for West Nile virus. Additionally, mosquito larvicide is purchased and distributed to licensed mosquito control applicators from local municipalities and villages throughout the county. The larvicide is used to treat potential mosquito breeding sites. An annual education campaign focuses on the prevention and identification of potential breeding sites throughout the county. Identified sites are monitored and as needed re-mediated. Presentations about mosquitoes and the potentially life-threatening diseases they can carry are given to students throughout the county. Presentations and educational awareness are also conducted regarding ticks and the prevention of Lyme disease.
