Denton County is waiting to hear from dozens of municipalities about whether they want to be included in the county's aerial spraying for mosquitoes.
Flower Mound, Cross Roads and Pilot Point have already opted in, while Little Elm and Providence Village have voted against aerial spraying.
Denton County health officials said Carrollton, Dallas and Coppell also opted out because they participated in Dallas County's aerial spraying.
Dr. Bing Burton, Denton County Health Department director, said the county hopes to hear from 44 municipalities by noon on Tuesday.
"That is a lot of municipalities," he said.
The county confirmed its second West Nile virus-related death on Friday. There have been more than 118 human cases in the county so far this year.
Chris Rowe, who lives in Providence Village, said he supports his town council's decision to opt out of the aerial spraying.
"You don't know what they are putting in the air," he said. "You don't know what they are using. You don't know what the effect is. You just don't know."
Burton said he understands why people may be concerned about aerial spraying but county leaders are encouraging cities to take part.
"We believe the best thing we can do to protect the health of Denton County residents is aerial spraying," he said. "We have information from CDC and EPA and most recently from Dallas County Medical Society that says we believe the spraying is safe for humans and livestock."
Some of the larger cities in the county, such as Denton and Lewisville, have not made up their minds.
The Denton City Council will hold an emergency meeting Monday at 7:30 a.m. The Lewisville City Council will hold an emergency meeting at 6 p.m. on Monday. Both cities will continue to ground spray and use larvicide while they make their decisions.
