San Gabriel Valley Mosquito & Vector Control District joins effort to slow COVID-19 spread

While facilities are closed to the public, mosquito control field and digital services will continue in order to minimize future mosquito threats

SAN GABRIEL VALLEY, Calif. (March 16, 2020) –The San Gabriel Valley Mosquito & Vector Control District (SGVMVCD) will close its facilities to the public effectively Monday, March 16, as a precautionary measure to help slow the spread of COVID-19.

This follows existing social distancing guidance from the Los Angeles County Department of Public Health and California Department of Public Health.

“Our top priority is the health and safety of the public and our staff,” said District Manager Jared Dever. “While our office is closed to the public, our staff will continue to monitor and control for mosquitoes in our communities.”

SGVMVCD will postpone all existing in-person property inspections and community outreach activities, including classroom visits. Residents with existing appointments for service will be placed on a priority list once public health officials lift social distancing guidance. In the meantime, residents can still submit a tip about mosquito problems online at or by calling 626-814-9466.

Mosquito control inspectors will continue to monitor and treat for mosquito in public areas, such as channels and gutters. Surveillance of mosquito populations using traps will also continue. Public education outreach will continue on social media, online videos, and SGVMVCD website.

SGVMVCD is one of five vector control districts in Los Angeles County. Year-round, the agency monitors stagnant water sources, such as gutters, storm drains, channels and non-functional swimming pools. The agency also routinely monitors populations of adult mosquitoes using traps and tests groups of adult female mosquitoes for the presence of West Nile virus (WNV) and other mosquito-borne diseases. In addition, submitting wild birds, such as crows, for testing can provide insight into the spread of WNV.
