Operation’s goal is to effectively manage mosquito populations and prevent disease transmission. Long-term mosquito prevention is accomplished through Integrated Vector Management (IVM) which includes a combination of applied techniques involving physical, chemical, and biological control methods. Operations collaborates with Community Affairs and Scientific-Technical Services to ensure effective control of vectors in our environment.
Mosquito prevention and management is performed by dedicated Vector Control Specialists. Unique and highly specialized equipment gives Specialists the ability to effectively manage sources while minimizing the need for pesticides.
The diverse duties and responsibilities of the operational staff include inspecting properties, neglected swimming pools and ponds, freeway drains, spreading basins, lakes, wetlands, street gutters, and many other mosquito breeding sources. The operations staff work out of two locations; the District’s headquarters in Santa Fe Springs and the branch office in Sylmar. All full-time operations staff are licensed and certified by the State of California Department of Public Health in pesticide laws and regulations, mosquito biology, terrestrial invertebrates, and vertebrate vector control.
Underground Storm Drain System Team
Underground storm drain systems provide ideal habitat for adult and immature mosquitoes. Temperatures are moderate, humidity is high, and leaf litter and debris blocks water flow providing habitat for immature mosquitoes. Before 2001, GLACVCD field technicians spent countless nights flushing debris and stagnant water out of storm drains below downtown Los Angeles in response to service requests about mosquito problems. District Vector Ecologists would routinely trap thousands of mosquitoes in Los Angeles County’s underground storm drain system. To better and proactively manage these chronic mosquito sources, the District placed four full-time staff members in charge of controlling the mosquitoes in the 9,000 miles of urban, underground channels and conduits that transport urban run-off to the ocean.
Today, the program is a permanent sub-section of the Operations Department with 15 crew members from both the Sylmar and Santa Fe Springs offices. The team carefully manages 58 work zones and prioritize the systems for inspections and treatment. To date, the team has mapped 31,000 manhole covers which provide access necessary to ensure these systems are properly maintained.
