The Placer Mosquito and Vector Control District works hard to protect East Placer from mosquitoes, yellowjackets, and rodents. The northwest part of the Tahoe Basin is in Placer County and is part of the District’s service area. The District’s Tahoe Basin substation was opened in 2009 near Truckee to provide vector control services to eastern Placer County, help manage mosquitoes and yellowjackets, and assist the California Department of Public Health with the community-wide risk of rodent-borne diseases like plague and hantavirus.

Angella has been with Placer Mosquito and Vector Control District for over 15 years and has been the field station manager at the Tahoe Basin substation since 2014. Angella is the main point of contact for all activities in the Tahoe Basin area. Seasonally, the substation hires temporary employees during the busiest months between May and September.

The Tahoe Basin area has a diverse landscape and the vectors active in the area change during each season. Learn more about the substation and its priority areas below.

Service Requests

We respond to public service requests. For the fastest service from our technicians, submit problem reports for vector-related issues in the Tahoe Basin area here.


Mosquitoes in the basin mostly occur with the melting of snow and pooling of rainwater. Snowmelt and Treehole mosquitoes are aggressive biters but do not transmit diseases like West Nile virus. Read more about the different species of mosquitoes in the Tahoe Basin area here.


Yellowjackets do not carry disease but can cause uncomfortable stings and allergic reactions in some people.  Our trained technicians can inspect and treat yellowjacket nests that are causing problems. Read more about yellowjackets and their behavior here.


Rodents are associated with serious diseases like plague and hantavirus. The District assists the California Department of Public Health with mitigating community-wide risk and exposure. Read more about rodents in Placer County here.


Trained and certified drone pilots can access and treat environmentally sensitive areas in the basin. Drones are an important tool to protect public health in the Tahoe Basin. Learn more about our District’s drone program here.
