The San Mateo County Mosquito and Vector Control District has detected Aedes aegypti mosquitoes at 13 locations in 2014, all in Menlo Park in the area near Holy Cross Cemetery The first detection was on January 22 and most recently larvae were found on April 10.
The Aedes aegypti species is not native to California. However it is a common mosquito in urban areas of the southeastern United States. The yellow fever mosquito has the potential to transmit several viruses, including dengue and yellow fever. No illnesses associated with this mosquito have been reported so far.
The Mosquito and Vector Control District has expanded surveillance efforts for this type of mosquito. The district has deployed a variety of traps for adult mosquitoes and mosquito eggs surrounding the location where the Aedes aegypti mosquito was found. Additionally, District staff conducts door to door inspections of properties for mosquito breeding and standing water at homes surrounding each Aedes aegypti detection.
The Aedes aegypti species is a tiny (about 1⁄4 inch) black and white mosquito that bites most often during the day, and can transmit dengue, yellow fever, chikungunya, and several viruses that cause encephalitis. These viruses are not currently found in California.
The public can play a critical role in helping to control the spread of this mosquito population. The yellow fever mosquito lays its eggs in water, just above the water line in small containers and vessels that hold water, such as pots, pet bowls, bottles, and bird baths. It’s important for residents to survey their yard and around their house to eliminate even the smallest amount of standing water.
Residents experiencing mosquito bites during the day should report them to the San Mateo County Mosquito and Vector Control District (650) 344‐8592.
