Alameda County Mosquito Abatement presents West Nile surveillance and neighbourhood prevention tips to Newark council

Representatives of the Alameda County Mosquito Abatement District briefed the Newark City Council on their surveillance and control work, virus testing and community outreach, and urged residents to reduce standing water on private property.

Eric Henske, the city’s delegate to the district board, introduced Judith Pierce (listed in the presentation as Judith Pierce Davis Davidson), the district’s newly appointed public education officer. Pierce described how the district focuses on the larval stage of mosquitoes to reduce populations and explained that even small containers such as bottle caps can produce dozens of mosquitoes.

“Swimming pools that are neglected and stay still are opportunities for mosquitoes to breed,” Pierce said, and she described common breeding sites—green pools, old tires, gardening containers and marshland. She explained the district’s life‑cycle approach: eggs in standing water, larvae (“wiggly” stage), pupae, then adults. Pierce said larval treatment is the most effective control and that the district can treat pools or provide mosquito fish when appropriate.

Pierce detailed the district’s West Nile virus surveillance: collection and PCR testing of dead birds (often corvids) and monitoring using mosquito traps. She said Newark had a small number of virus‑positive dead birds in recent years and urged vigilance. “When we start to find dead birds around, that’s one of our first indicators that it could be West Nile virus,” Pierce said.

Council members and residents asked about responses to complaints about neglected pools and about the use of fogging. Pierce said staff initially investigate to confirm whether mosquitoes are the issue, then follow with targeted monitoring and treatments. She said the district coordinates with other vector agencies and noted that fogging is used selectively and focused on blocks with confirmed virus activity rather than entire cities.

The district highlighted its outreach efforts in local schools (Birchgrove, Intermediate and Lincoln Elementary) and asked the city to share information about dead birds, pools and breeding sites. Pierce said the district’s annual cost to residents is modest—average below $5 per year in the service area—and the district provides guidance without judgment to homeowners needing help with pool treatment.

Council members thanked the district for outreach and for school programming and encouraged continued partnership on public education and info fairs. The council did not take formal action on the presentation.

For residents: the district recommended eliminating standing water, calling the district for pool‑treatment assistance, reporting dead birds and sharing information with animal control when appropriate. Pierce said that rapid reporting helps the district target surveillance and control work.
