ROSEVILLE -- The Placer Mosquito & Vector Control District says 14 cases of West Nile have been detected in Placer County.
Traps were put out at nine locations Monday with the positive cases found in the labs Wednesday Morning.
"We immediately started spraying, as part of our year-round effort to combat West Nile," General Manager Joel Buettner said.
Prior to Wednesday's findings Placer Vector Control says 12 cases have been positively identified so far in 2016 - meaning the recent findings double that number, as it stands at 26 positive tests.
Of the 14 cases, 13 were found in the agricultural area west of Roseville -- far from residential areas.
Vector control says the heat allows for the spread of West Nile, and that they will continue overnight aerial spraying along with ground level spraying in needed areas.
