The mosquito control program in San Mateo County is one of the oldest in the United States. Control work was initiated in 1904, when the Burlingame Improvement Club asked entomologists from the University of California to assist them in developing a plan to fight the city’s mosquito infestations. H.J. Quayle, an entomologist with the University Experiment Station, conducted a preliminary survey. He determined that 95% of the mosquitoes biting residents were arising from diked reclaimed salt marshes along San Francisco Bay.
