Summary

A district representative updated the Hughson City Council on staffing, testing for West Nile, aerial and drone spraying, a Wolbachia sterile-male program for Aedes (Asian tiger) mosquitoes and recent legislation (SB 1251) that the district says will improve access to problem sites.

A representative of the mosquito abatement district briefed the Hughson City Council on the district’s staffing, finances and control methods, saying the agency is preparing for the April–August mosquito season and continuing disease surveillance.

The presentation, given during the council meeting, outlined the district’s workforce, field operations and laboratory testing. “We have 12 full‑time employees. We have seven seasonal” staff who return for the busy months, the district representative said. The representative added the district manages “approximately $3,600,000 total” in funds used for operations, contracts and emergency responses.

The district described its surveillance and treatment practices and said it tests mosquito samples for pathogens, including West Nile virus. The representative said, “If we do have an outbreak in West Nile, the procedure is to notify the local public health department and then it goes up to the state,” and that the district documents and reports where treatments occur.

Operations described included contractor aerial spray flyovers performed at night, ground treatments where accessible, and use of remotely piloted equipment. The district said it purchased a heavy‑payload drone platform to reach sites inaccessible to all‑terrain vehicles; the representative said the platform cost roughly $60,000–$65,000 and must be transported in a secure cradle.

The district also described a biological control effort targeting Aedes (Asian tiger) mosquitoes. Staff said the district is partnering with a vendor that supplies males infected with Wolbachia bacteria; the males do not bite, mate with local females and reduce their ability to reproduce. The representative described weekly field releases of males and said the program is costly and budgeted for specific target areas.

On funding and assessments, the district said its work is supported in part by a property assessment that amounts to about $5 per household and that larger assessments apply to agricultural properties. The presentation noted significant seasonal cost pressures and a line item for emergency spending in recent wet years.

The district said it relies on outside laboratories for some testing and estimated a program‑scale cost of about $2,530,000 where lab capacity or expanded surveillance is required. The representative said federal and state agencies, including the EPA and state public health bodies, monitor and encourage the district’s surveillance activities.

The presentation closed with a legislative update: “The legislature just passed SB 1251, which will allow districts to access underground utility boxes” that can collect standing water, the representative said. The district said it expects to work with irrigation districts and utility owners to obtain access under the new law.

Council members and meeting attendees thanked district staff for the briefing and for the work to keep the community safe; no formal council action on the briefing was recorded in the transcript excerpt.
