Plans call for aerial misting for areas missed on Friday
More aerial spraying for mosquitoes is planned for Sunday night in some southern parts of Denton County after winds prevented those areas from being sprayed Friday.
Dynamic Aviation and Clarke, a mosquito control company, began aerial spraying in several parts of the county Friday night to prevent the spread of West Nile virus. County Judge Mary Horn issued a health emergency Aug. 22 and called for the spraying.
“We ended up with some challenges with some winds,” said Laura McGowan, spokeswoman for Clarke.
About 80 percent of the prescribed spraying was completed by early Saturday morning, but over the course of the night, the winds became too high, she said. Areas of Lewisville, Flower Mound, Haslett and Southlake were not sprayed, McGowan said.
About 250,000 acres were sprayed Friday night. All the prescribed areas were to be sprayed between 9 p.m. Saturday and 2 a.m. today.
Then beginning at 9 p.m. today, officials plan to spray the 20 percent that wasn’t sprayed Friday.
“That’s the goal at least, if the weather cooperates,” McGowan said.
The entire area needs two applications of the spray, she said.
The Denton County Health Department has reported 77 positive mosquito pools and 145 human cases of West Nile virus — with 102 cases diagnosed as West Nile fever, which has milder symptoms, and 43 diagnosed as the more serious neuro-invasive disease.
Traps were put out to collect mosquitoes Thursday night before the spraying began, and more traps will be put out once the spraying is complete, McGowan said.
Dynamic Aviation is posting updates about the progress of the spraying via its Twitter account at http://twitter.com/AerialMosquito.
