The Richardson Health Department plans to spray for mosquitoes in two sections of the city east of US 75 after traps tested positive for West Nile virus.

Workers will spray between 9 p.m. and 4:30 a.m. Sept. 14-15 in both areas. One spray area will be from Plano Road east to the President George Bush Turnpike between Renner Road to the north and Lookout Drive to the south. The other spray area will be from Greenville Avenue east to the railroad tracks west of Bowser Road between Arapaho Road to the north and Walnut Street to the south.

Richardson health officials previously alerted residents to plans to spray various sections of the city each of the last six weeks.

Richardson officials are working with other health agencies in the metroplex to contain the spread of the West Nile virus, according to a city news release. Measures being taken include traps being set across the city to monitor mosquito populations, reducing water levels where needed and collaborating with regional partners to improve the monitoring of the virus.

Richardson offers an interactive mosquito map on its website that allows residents to find out the latest test results in their area.

Additional information about Richardson’s mosquito control program is available on the city website.
