San Mateo County Mosquito & Vector Control District Takes Steps to Protect Staff and Public from COVID-19

Mar. 18th, 2020

San Mateo County Mosquito and Vector Control District is taking proactive measures to protect its staff and residents by taking action to slow the spread of novel coronavirus (COVID-19).

Starting Tuesday, March 17th, the District is no longer responding to resident service requests, but vector control technicians will continue to monitor and treat for mosquitoes. Laboratory staff will continue to conduct invasive mosquito and disease surveillance programs. Additionally, public information programs will continue online through social media and the District’s website. Outreach and community events will be suspended until further notice. Steps have been taken to ensure that staff are able to complete their work while maintaining appropriate social distancing.

It is important to remember that COVID-19 is NOT transmitted through the bite of a mosquito. However, other viruses, such as West Nile virus, can be. Therefore, residents are asked to be proactive in the coming weeks as they stay close to home by eliminating mosquito sources around and inside their property. The following steps will help reduce the threat of mosquito-transmitted diseases and mosquito breeding this coming season:

  • Eliminate standing water in clogged rain gutters, rain barrels, buckets, watering troughs, plant saucers, flower pots, or anything that holds water for more than a week.
  • Ensure that swimming pools, spas, and ponds are properly maintained.
  • Change the water in pet dishes, birdbaths and other small containers weekly.
  • Make sure that doors and windows have tight‐fitting screens to keep out mosquitoes and repair or replace screens with tears or holes.
  • Apply insect repellents that contain DEET, picaridin, oil of lemon eucalyptus, or IR 3535 when spending time outdoors if mosquitoes are present. Always follow label instructions.

For more information on steps residents can take to prevent mosquito breeding, visit our website at or call (650) 344-8592.

In addition to taking proactive measures to control mosquitoes, we also strongly encourage residents to take everyday actions to prevent the spread of COVID-19. These recommendations are available from San Mateo County Health at

The District will continue to assess its operations daily and monitor public health guidelines for further changes. We will keep you informed of any changes and appreciate the support and understanding of residents as we respond to this challenging situation.
