Officials at San Mateo Mosquito and Vector Control District (SMCMVCD) remind residents that winter is the season for the western black-legged tick (Ixodes pacificus), also known as the deer tick. This tick is the primary vector for Lyme disease and other common tick-borne illnesses.
As invasive Aedes aegypti and Aedes albopictus mosquitoes increase their range in California, the District is always on the lookout for these species in San Mateo County. We always appreciate residents’ help in watching for these invasive mosquitoes, but so far in 2016 (fortunately!) none have been found.
