UPDATE 1:15 p.m.: Strong winds cut short the aerial mosquito spraying Friday night in Flower Mound, according to the Denton County Health Department.
Portions of Flower Mound south of FM 1171 were not sprayed after winds picked up near the end of the night, health officials said Saturday morning.
Denton County, in partnership with Clarke Aviation, plans to conduct the second round of aerial mosquito control spraying over the entire area tonight and cover the missed portions in Flower Mound and other missed areas on Sunday night.
Lantana, Highland Village, Double Oak, and Copper Canyon were sprayed last night and will receive their final application tonight.
Four planes began spraying at 9 p.m. Friday in eleven spray blocks comprising the participating Denton County towns and unincorporated areas.
At first, the wind conditions in the extreme southwest portion of the county were calm, even at the 300-foot application altitude. This required one plane to be relocated to another block with suitable conditions. Planes need slight winds to successfully apply the insecticide.
During the first load around midnight, the pilots reported ideal wind conditions throughout the spray blocks.
However, gusty winds over 15 miles per hour prevented portions of Flower Mound, Lewisville, Haslet and Southlake from being completed. In order to accurately release the mosquito control spray, wind conditions must be below 10 miles per hour.
The last spray-off was 3:33 a.m. All four planes were back to base at Denton Airport by 4 a.m. A total of 226,220 acres were sprayed, or 80.7 percent of the assigned acreage.
