Watertown Rolls Out 2024 Mosquito Control Efforts to Combat West Nile Virus

The City of Watertown is preparing for its 2024 Mosquito Control Program to reduce the risk of West Nile Virus, which is spread by mosquitoes. In Watertown, located in South Dakota, 43 mosquito species exist, but only 19 can carry the virus. Although few mosquitoes carry the virus and human infections are rare, the city is committed to effective mosquito control.

The main approach involves targeting mosquitoes at the larval stage in water. By eliminating standing water and using an organic larvicide, the city aims to decrease the number of adult mosquitoes. The larvicide, safe for humans and animals, targets only mosquito larvae. The city plans regular treatments during the mosquito season, including at public breeding sites and storm drains.

Additionally, the city monitors adult mosquito populations and sprays areas as needed, based on data from mosquito traps. Spray times and locations are announced through local media and the city’s website, typically occurring from dusk to dawn.

Residents are advised to reduce exposure to mosquito sprays, especially those with chemical sensitivities or health conditions. Recommendations include staying inside during spraying, closing windows, and turning off air conditioners that pull in outside air. After spraying, it is advised to wash any exposed skin and rinse homegrown produce.
