A request by the city of Irving to have a thin strip of land sprayed with adulticide by air has been denied.
The city had opted-out of aerial spraying done over Dallas County earlier this month and favored only spraying this small, targeted area.
The area is adjacent to a waterway and Clarke, the company doing the spraying, said the area to be sprayed didn't meet the minimum threshold amount and they recommended ground spraying instead, according to a report in the Dallas Morning News.
The city will continue spraying for mosquitoes by ground with the next round of spraying scheduled for Wednesday night. Spraying will begin at 10 p.m. and will continue until it's completed, weather permitting.
Ground spraying in Irving is managed by Dallas County Health and Human Services.
