Yellow fever mosquitos were recently spotted in Menlo Park. Although there have been no reported human illnesses from the mosquitos, they still pose a threat.


The species of mosquitos responsible for carrying yellow fever is the Aedes aegypti. The goal of the San Mateo County Mosquito and Vector Control District is to eradicate the eggs of these mosquitos.


The Aedes aegypti is roughly ¼ inch long with black and white coloring. They are more often found in the southeastern United States but have made an appearance in California.


On November 2, the Menlo Park Fire Protection Community Emergency Response Teams (CERTs) worked with the San Mateo County Mosquito and Vector Control to help conduct a community campaign for informing Menlo Park residents about the mosquito.


These mosquitos typically bite during the day; residents who have been bitten by mosquitos are asked to report to the San Mateo County Mosquito and Vector Control District.


Additionally, residents are advised to use insect repellent, wear long sleeved clothing and keep doors shut to help diminish the spread of the disease.


Standing water is a one of the most prominent breeding habitats for mosquitos. Abandoned pools can be very dangerous, as they can become a mass-breeding hub. Individuals should take steps to eradicate any source of standing water on their property.
