City health officials previously alerted residents to plans to spray sections in the northeastern part of the city Aug. 3-4 and Aug. 10-11.

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.
