Vector Disease Control International has confirmed Lewisville’s 16th, 17th and 18th positive West Nile Virus mosquito traps for 2017.

Weather permitting, VDCI will spray within a half-mile radius of each positive testing location on Tuesday, Aug. 22, and Wednesday, Aug. 23. Trucks operated by Vector Disease Control International will conduct the spraying around 9 p.m. each night.

The 16th positive sample was collected Aug. 17, from a trap located in the 500 block of Legends Drive, from the 500 block of Legends Drive, south of E. Main Street and west of Railroad Street.

The 17th positive sample was collected Aug. 17, from a trap located in the 2600 block of Lake Ridge Road. One positive mosquito sample was previously collected from this trap on July 13.

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

Denton County reported its second human case of West Nile virus, specifically West Nile fever, on Aug. 16. The person contracted it in an unincorporated area east of Lewisville.

An automated “call out” from the City of Lewisville will happen tonight at 6 p.m., notifying residents in all three areas that a positive trap was collected and where spraying will occur.

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.
