In California ticks are ready to bite year-round, but there are peak periods for some ticks in certain stages of their life cycle. Winter happens to be when the adult ticks that can cause Lyme disease are most active.
In 2019 in Sonoma and Marin counties, about 1.1 percent of adult ticks and 5 percent of nymphs tested were infected with Borrrelia burgdorferi, the causative agent of Lyme disease, said Nizza Sequeira, spokesperson for Marin-Sonoma Mosquito and Vector Control District.
