The city of Lewisville is reporting its 17th positive West Nile virus mosquito trap of 2016, and ground spraying is set for Tuesday and Wednesday.

The sample was collected Sept. 8 near the 500 block of Legends Drive, south of E. Main Street and west of Railroad Street the city said in a press release Monday.

Previous positive samples were collected from this trap on June 30, July 7 and July 28.

The finding was confirmed by Vector Disease Control International, a company which contracted with the city to confirm test results. The private company has its own certified lab and technicians who can confirm test results quicker than the state health department.

Ground spraying is scheduled for a half-mile radius of the trap, beginning at 9 p.m. on both Tuesday, Sept. 13, and Wednesday, Sept. 14.
