Vector-control official warns of Aedes aegypti, urges residents to remove standing water
Summary
Orange County Mosquito and Vector Control public information officer briefed Rossmore directors on the local risk from Aedes aegypti and dengue, described surveillance and control tactics, and urged residents to eliminate tiny breeding sites and use the district's free services.
Brian Brandon, public information officer for the Orange County Mosquito and Vector Control District, told the Rossmore board June 11 that Aedes aegypti (the so-called "ankle-biter") breeds in very small amounts of water and can transmit dengue. Brandon said mosquito season is beginning after recent rains and that residents should eliminate standing water down to bottle-cap-sized containers.
Brandon described the district's integrated vector-management approach: education, surveillance (trap grid monitoring and disease testing), larval control (BTI dunks), and limited ultra-low-volume adulticide application only when disease presence requires it. He stressed careful product selection and environmental caution and said residents can submit anonymous service requests for inspections.
On locally transmitted dengue, Brandon cited recent cases in nearby jurisdictions (Long Beach and Pasadena) as reasons for heightened vigilance and explained the agency's investigation and targeted response to travel-associated or locally transmitted cases. He also described pilot programs the district is testing (including drone BTI application and a sterilized-mosquito approach) and recommended that residents call the district for problematic water features or to request mosquito fish for large ponds.
The board thanked Brandon and approved a proclamation designating June as Mosquito Awareness Month.
