Abstract: The Coachella Valley Mosquito and Vector Control District (District) boundary encompasses 2,400-square-mile area where residential communities create suitable urban habitats for breeding mosquitoes, including bird baths, buckets, plant saucers, potted plants, tires, and other artificial containers in residential properties. The Coachella Valley includes nine urban cities and unincorporated sections of Riverside County. The primary objectives of the District are to reduce mosquito populations that could lead to public health issues or nuisance problems, particularly those resulting in disease outbreaks. Since the detection of Aedes aegypti in 2016, the District has implemented control measures to reduce its spread throughout the Coachella Valley. District staff are using all available tools in the mosquito control toolbox to help residents reduce their exposure to Aedes aegypti mosquitoes. This poster outlines the control efforts the District implemented in 2025 to reduce residents' exposure to Aedes aegypti mosquitoes in targeted areas. Additionally, the poster will provide details about the operational activities conducted in 2025, specifically focusing on truck-mounted larvicide applications in the cities of the Coachella Valley. Lastly, the poster will present an operational plan, facilitating effective communication within the District, and the community.
