The 18th positive sample was collected Aug. 17, from a trap located in the 200 block of Highland Drive, north of State Highway 121 and east of Denton Tap Road. Three positive mosquito samples were previously collected from this site on July 13, Aug. 3, and Aug. 14.
All three locations are core testing sites in the city. It’s important to 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.
Weather permitting, ground spraying/fogging will be conducted in a half-mile radius of each testing location on Tuesday and Wednesday. Trucks operated by Vector Disease Control International will conduct the spraying around 9 p.m. each night. The insecticide being used is registered with the Environmental Protection Agency and poses minimal risk to humans, pets and the environment.
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.
