Vector control warns of dengue risk, outlines sterile-mosquito program and resident services
Summary
A Greater Los Angeles County Vector Control District representative told the La Habra Heights City Council that travel-related dengue cases rose to roughly 140 last year and described surveillance, mosquito fish, storm-drain work and a sterile-insect technique to reduce mosquito populations; residents were urged to report standing water and use the district’s outreach toolkit.
David Palin Jr., a representative of the Greater Los Angeles County Vector Control District, told the La Habra Heights City Council on June 9 that mosquito season is underway and urged residents to be vigilant against disease-carrying mosquitoes.
Palin said the district recorded about 140 travel-related dengue cases last year and remains concerned about West Nile virus and occasional detections of other mosquito-borne pathogens. He described the district’s integrated vector management approach—surveillance, control and public education—and explained how technicians respond to service requests, inspect properties and treat public water bodies, gutters and green pools. The district funds services in part through an annual parcel charge Palin identified on the record as $18.97 per residence.
Palin described lower-visibility operations such as underground storm-drain inspections and removal of debris from flood channels, and said technicians also deploy biological controls such as mosquito fish to reduce larvae in standing water. He highlighted a longer-term program known as the sterile insect technique—releasing irradiated male mosquitoes so that resulting offspring are not viable—as an environmentally friendly, nonchemical option being developed to reduce local mosquito populations.
The district’s communications team, Palin said, is increasing outreach to schools and community events and offers a social-media toolkit and print materials the city can redistribute. He urged residents to call or file service requests through the district’s website when they identify standing water or suspected breeding sites so technicians can follow up with inspections.
The presentation closed with a question-and-answer session in which councilmembers asked about geographic distribution of cases; Palin said cases have been concentrated near the San Gabriel foothills but have been detected across Los Angeles County because many are travel-related. Staff and council thanked the district for its services and encouraged residents to use the district’s reporting tools.
Councilmembers did not take formal action on the presentation. The city retained the handout Palin provided for the administrative record.
