Dallas County reported its 11th West Nile virus-related death on Tuesday. The victim was an 80-year-old woman who lived in a zip code that covers parts of University Park and Dallas.
Dallas Mayor Mike Rawlings says the city is done with aerial spraying for at least 10-14 days.
"Initial results are in ... showing us that aerial spraying is working with no visible side effects," Rawlings said.
Rawlings said the window of time is to allow for mosquito larvae to hatch and for more data to be collected from active mosquito pools.
The data collected will be turned over to the Centers for Disease Control who will then advise the city on and county on their progress and status.
Meantime, the city now plans to take the fight to the ground by taking a targeted approach using trucks in certain locations at a localized level.
With recent heavy rainfall, Rawlings renewed a call to citizens to stay vigilant in removing standing water or calling 311 to alert the city to standing water or mosquito habitats.
