Duncanville has decided to move forward with ground spraying in areas that have large amounts of mosquitoes.
The City Council voted to approve spraying for the near future after finding more than a 1,000 mosquitoes collectively in three different traps.
One of the traps was placed on a street where a victim died of West Nile virus last year.
No mosquitoes have tested positive for West Nile virus.
Until now, Duncanville only conducted ground spraying with authorization from the City Council when there was a confirmed presence of the virus. On Tuesday night, the council agreed it would review the policy to allow spraying without its authorization or the presence of the virus.
Judy Uehara, who contracted West Nile virus last year, lives on one of the Duncanville streets where the extremely large mosquito population was detected this year.
"You can't come outside without getting bitten," she said. "I can't take my children outside."
She said she does not want delays to slow prevention measures that might save other people from what she suffered.
"I've told people it felt like somebody was cannibalizing my legs," she said. "It hurt so bad to stand up."
Meanwhile, Dallas plans to conduct ground spraying after discovering mosquitoes infected with West Nile virus for the first time this season.
On Wednesday night, the city will spray the area bounded generally on the north by Goldfield Drive, on the west by Lawton Drive, on the south by Suetelle Drive and on the east by Cliffview Drive.
Dallas was already spraying eight locations on Monday and Tuesday nights. West Nile virus had not been detected in those areas, but they had an extremely large mosquito population.
Dallas County health officials recommended the more aggressive prevention measure.
"That may be somewhat different, but you've got to remember, a lot of things have changed," said Zach Thompson, county health director. "We didn't have an epidemic in previous years until last year."
Twenty Dallas County residents who contracted West Nile virus during the 2012 mosquito season died, and hundreds more were sickened.
This month, Lancaster and DeSoto have also agreed to the preventive spraying of high mosquito population areas without West Nile virus confirmed.
