Placer Mosquito & Vector Control warns Loomis about Aedes aegypti, details surveillance and local services

The Placer Mosquito and Vector Control District presented its annual update to the Loomis Town Council, outlining surveillance activities, control methods, community services and a warning about an invasive species that reproduces in small, backyard water sources.

Assistant Manager Jay Cardell said the district performs surveillance with a countywide network of traps, conducts chemical, biological (mosquito fish) and physical source‑reduction treatments, and uses drones and AI tools for targeted work. Cardell named two technicians assigned to Loomis (Derek and Steve) and said residents may submit service requests through the district website for inspections and treatment.

Cardell emphasized West Nile virus monitoring and explained the process for testing dead corvids. He also raised the district’s growing concern about Aedes aegypti — a day‑biting, human‑preferring, urban mosquito that can reproduce in a capful of water — and said dengue, chikungunya and Zika are not currently present in Placer County but that the species could spread those diseases if they arrive.

The district advised residents to eliminate standing water, maintain fountains so water moves, use EPA‑registered repellents (DEET or Picaridin), keep screens in good repair and report dead birds. Cardell described door‑to‑door outreach in neighborhoods where invasive species have been detected and said school and library outreach events continue.

What’s next: the district will continue surveillance, expand door‑to‑door inspections where needed and provide service support to Loomis residents on request.
