San Gabriel Valley Mosquito District warns of dengue risk, plans sterile‑male pilot in Bassett Park
Summary
District Manager Jason Fernando told the West Covina City Council that invasive Aedes aegypti and extreme weather have increased local vector‑borne disease risk; the district will pilot a sterile‑male release in Bassett Park this summer and offers free property inspections and outreach.
The San Gabriel Valley Mosquito and Vector Control District briefed the West Covina City Council on April 21 about shifting mosquito risks in Southern California and the district’s response plans, including a pilot for sterile‑male mosquito releases in Bassett Park this coming summer.
District Manager Jason Fernando said the district, which serves roughly 1.5 million residents across 26 cities, treats mosquitoes as a public‑health issue rather than solely a nuisance. He highlighted the emergence of locally transmitted dengue cases in recent years and noted that invasive species such as Aedes aegypti and extreme weather events have complicated control efforts.
Fernando outlined the district’s integrated vector management strategy—surveillance, targeted control, and outreach—and described specific services available to West Covina residents: free property consultations, a reporting tip line, mosquito fish for ponds and non‑functional pools, and door‑to‑door education. He provided the district website (sgvmosquito.org) and a phone number (626‑814‑9466) for residents to request inspections.
On innovative control tools, Fernando said researchers and districts are experimenting with sterile‑male techniques—releasing sterilized males that mate with wild females to reduce viable offspring—and that the SGV district will run a proof‑of‑concept pilot at Bassett Park this summer to assess efficacy and cost.
Council members and residents asked practical questions about repellents, plant‑based deterrents, and the cost of residential inspections. Fernando said residential property inspections are free and funded through a property assessment, and recommended CDC‑approved repellents for personal protection.
The district emphasized that mosquito control is a shared responsibility and encouraged residents to remove standing water and participate in community education. Fernando also described a large mobilization after last year’s Eaton fire when the district assessed and treated about 1,000 damaged pools to reduce mosquito habitat.
The presentation concluded with council appreciation and a reminder that the district can conduct community presentations and classroom trainings to support neighborhood prevention efforts.
