City to spray following 19th West Nile positive mosquito test


Vector Disease Control International has confirmed the city’s 19th positive West Nile Virus mosquito trap for 2017.

The positive sample came from a trap collected August 24, from the 600 block of Holfords Prairie, in an area between State Highway 121 and Business 121. This area is one of nine core sites regularly tested for the mosquito born virus. Five positive mosquito tests were collected from this same trap on July 13, July 20, July 27, Aug. 3, and Aug. 10.

Ground spraying will be conducted in a half-mile radius of the testing location on Tuesday, Aug. 29, and Wednesday, Aug. 30. An automated “call out” from the City of Lewisville will happen tonight at 6 p.m., notifying residents that a positive trap was collected and where spraying will occur. Weather permitting, trucks operated by Vector Disease Control International will begin the spraying at 9 p.m. The insecticide being used is registered with the Environmental Protection Agency and poses minimal risk to humans, pets and the environment.

Please note that all the positive tests to date in the City of Lewisville have been in mosquitos. There have been no positive human cases reported to the city yet.

City crews are regularly walking through and visually inspecting creeks and drainage channels to look for potential mosquito breeding sites. The city has nearly a dozen workers in the Parks and Animal Services divisions who are state-certified to apply anti-larval dunks or localized pesticide to curb the mosquito population.

Residents are encouraged to report any mosquito complaints to Chris McGinn at 972-219-3484.
