WILLIAMSON COUNTY, Texas (KXAN) — A mosquito sample in Bartlett has tested positive for West Nile Virus. It’s the same city where a human tested positive for the virus earlier this summer.
The species of mosquito that tested positive was a Culex quinquefasciatus, (Southern House Mosquito) which carries the West Nile Virus.
“The small nature, the size of their town, one flat radius for these mosquitoes covers the whole town,” says Teel. “So when these mosquitoes hatch they could fly the full length and breadth of Bartlett,” explains John Teel, executive director of Williamson County and Cities Health District.
The district will work with the city of Bartlett and the Bell County Health District to continue additional trapping and testing. The health department will also contract with a Dallas company to have trucks start spraying for mosquitoes.
“Depending on wind speed and based on rain for next week, we would like to start spraying Wednesday night and spray three consecutive nights, but all that depends on weather at the time,” says Teel.
The city will notify residents of the spray dates when the timing is confirmed. The spray area will be a one-mile radius from where the trap site was located, which includes most of Bartlett. In the meantime, the city will be treating standing water with larvacide.
“These mosquitoes can breed, they’ll be hatching off in the next 7 to 10 days in higher numbers than we’ve been seeing,” says Teel.
Bartlett resident Barbara Sandobal received a letter from the city letting her know about the case of West Nile. She says spraying is just a step in the right direction.
“The city needs to get started on cleaning the ditches and cutting all the tall grass down.”
Earlier this month, Williamson County said new mosquito samples from Cedar Park showed no signs of West Nile after a sample tested positive in July.
There have been no reported human cases of West Nile Virus in Williamson County since 2014; however, Bell County has reported one human case of West Nile Virus illness in June 2016. Bell County covers half of the city of Bartlett.
