The Placer Mosquito and Vector Control District detected an invasive (non-native) species of mosquito on Wednesday, August 28, 2019. The Aedes aegypti, commonly known as the yellow fever mosquito, was found in a residential south Placer County neighborhood east of Auburn Boulevard at Interstate 80. A second mosquito was detected on Wednesday, September 4. There have not been any additional detections but the District continues to monitor the infestation.
The District’s approach for the detected mosquito area is conducting door-to-door property inspections. The District is also coordinating with the Sacramento-Yolo Mosquito and Vector Control District on efforts since the mosquito was trapped near the county border. The District is doing everything we can to conduct eradication efforts to protect our residents and public health. Read more.
WEST NILE VIRUS
The District reported the first positive Placer County West Nile mosquito samples in July 2019. The samples were collected from sites along the County’s western border. District staff continues to find positive mosquito samples throughout western Placer agricultural areas. The District will manage WNV risk by making appropriate treatment plans as needed. Read about planned treatments.
We anticipate WNV season will come to a close with seasonal weather changes in the next month.
