The Greater Los Angeles County Vector Control District briefed Maywood City Council on May 28 about its surveillance, control and public‑education work, including a nonchemical sterile‑male pilot release intended to suppress mosquito populations.

District staff explained the agency performs year‑round work that includes inspections and treatment of storm drains, flood control channels and abandoned pools; mosquito trapping and species identification; dead‑bird testing; and laboratory testing for West Nile and dengue viruses. Staff said West Nile remains endemic in Los Angeles County and that dengue had produced locally acquired cases in 2024, highlighting the need for continued surveillance.

The district described integrated vector management practices: property inspections and public‑source treatments, targeted work in underground storm drain systems, physical debris removal and coordination with partner agencies to restore flow, and public outreach at community events. Staff said annual assessments include more than 600 source inspections in the service area cited last year.

District staff also described a sterile‑male mosquito release pilot conducted last year using x‑ray–sterilized male mosquitoes. The district said the approach is nonchemical, eco‑friendly and produced positive early results in the pilot area; officials said they plan further releases if the approach continues to prove effective. The district asked cities to help publicize reporting channels for standing water, dead birds and mosquito bites and to coordinate on park and stormwater sites that warrant inspection or additional treatment.
