West Nile virus (WNV) continues to spread in the Coachella Valley, with eight additional mosquito samples testing positive for the virus this week in the east Valley and one sample testing positive from Palm Springs.

This brings the total count of WNV-positive mosquito samples in the Coachella Valley to 30 in 2013. Last year at this time, there were 107 WNV-positive mosquito samples. 

In response, the Coachella Valley Mosquito and Vector Control District has intensified both its larval and adult mosquito surveillance and control in areas where WNV activity is on the rise.

In an effort to control adult mosquito populations and reduce WNV transmission, District technicians will conduct ground ultra low volume (ULV) applications south of Mecca starting Friday, September 6, for three consecutive nights, between 7 and 10 p.m. weather permitting, For more information regarding this application and for the route map, please visit the District's website at
