Flower Mound will begin targeted ground spraying this week.
The town has identified two neighborhoods with an unusually high number of human cases of West Nile virus.
One neighborhood is south and east of Cross Timbers and Long Prairie roads extending to Firewheel Drive. The other is the Glenwick Estates subdivision, which is north of Cross Timbers Road between Bridlewood Boulevard and Long Prairie Road.
A total of nine human West Nile virus cases have been reported in the two neighborhoods this season.
A Flower Mound representative confirmed that some of the cases were reported after aerial spraying but also pointed out that some of those people could have been infected before the spraying.
To be safe, the town will begin targeted ground spraying in both neighborhoods on Thursday for three consecutive nights of spraying.
The spraying will be done between the hours of 10 p.m. and 6 a.m.
