Denton County officials say they are confident that aerial spaying reduced the number of mosquitoes carrying West Nile virus.

The county conducted aerial spraying on Friday, Saturday and Sunday nights.

It will take a week or two for official results to come in, but county leaders say there are signs that the spraying effort affected Denton County's mosquito population.

"The official numbers aren't in as to how the spraying was, but I can tell you that some of the traps that we had set on Sunday night that got sprayed over ... had 100 percent kill rate in those traps after the spraying," Denton County Emergency Services spokesman Jaime Moore said.

Daniel Moon, who runs an organic farmer in Ponder, was concerned about the spraying before it took place but said he was pleasantly surprised by the results on his farm.

"I was concerned possibly for the predatory insects, especially the nocturnal ones like the praying mantis and the wheel bugs," he said. "I haven't seen a significant lowering in their population or anything that would correlate to the spraying."

County health officials continue to stress the importance of wearing insect repellent and using larvicide in standing water. They said it is important to remember that aerial spraying is not the only line of defense against mosquitoes and West Nile virus.
