The residential neighborhood of south Placer County east of Auburn Boulevard at Interstate 80 is scheduled for ground-based larval mosquito treatment tomorrow morning, Tuesday, September 3, from 2:00-4:00 a.m.
We detected an invasive (non-native) species, Aedes aegypti, commonly known as the yellow fever mosquito, on Wednesday, August 28 in this neighborhood. We are partnering with the Sacramento-Yolo Mosquito and Vector Control District on this ground-based treatment because the mosquito was trapped near the county border.
WHAT: Aedes aegypti
The Aedes aegypti mosquito has been found in several Central Valley and southern California counties, including recent initial detections in San Joaquin and Stanislaus counties. The mosquito is small and dark with a white violin-shaped marking on its body. Aedes aegypti can transmit several viruses, including Zika, dengue, chikungunya and yellow fever. These viruses, however, have not been found circulating in California.

ABOUT LARVAL MOSQUITO TREATMENTS
Larval mosquito treatments involve an EPA-registered biorational* mosquito larvicide to prevent adult mosquito development and reduce mosquito-transmitted disease risk. This larvicide is a specific product for Aedes aegypti and works to control mosquito larvae in confined areas.
District’s Approach to Mosquito Control
- Most mosquito control strategies implemented by the District are designed to prevent mosquito eggs and larvae from developing into adult mosquitoes. The District’s preferred larvicide strategies use biological control methods such as mosquito-eating fish and biorational materials applied directly onto fields and pastures.
- *Biorational larvicide is derived from a variety of biological sources including bacteria, viruses, fungi, protozoa and man-made naturally occurring biochemicals equivalents like pheromones and insect growth regulators. They are considered third-generation pesticides and are environmentally sound and closely resemble chemicals produced by insects and plants.
- The EPA considers biorational materials to have different modes of action than conventional materials with greater selectivity and considerably lower risks to humans, wildlife and the environment.
Please note: Since several factors like weather conditions affect treatment activities, the District encourages Placer residents to check this website regularly for any changes to the treatment schedule.
