San Mateo County: Tick Surveillance

Entomology Report November/December 2007, San Mateo County Mosquito Abatement District

This year, the lab will be measuring relative density and seasonal distribution of western black-legged ticks at five parks: Costanoa Lodge, Huddart Park, Skyline Ridge Open Space, Pulgas Ridge Open Space, and San Pedro Valley County Park. These parks represent the varied climates of the north, south, mid-, and coastal areas of the county. The study is designed to look at differences in the timing of tick activity in different parts of the county.

Additional testing for Lyme disease spirochetes will be conducted on ticks from Water Dog Lake and Camp Jones Gulch.
