Identification & Info

The District can identify resident-submitted ticks but DOES NOT perform disease testing on resident-submitted ticks. You can contact San Mateo County Health if you are interested in getting a tick tested.

Tick Collection and Testing

District staff regularly collect ticks at local parks each year for testing.

Study of ticks on residential properties

In 2022, the District started a study to assess tick presence on residential properties in San Mateo County. Information from the study will be used to develop more targeted outreach materials to address knowledge, attitudes, and practices regarding ticks and tick-borne diseases in San Mateo County. The cities of focus in late 2022 to early 2023 will be Pacifica and Hillsborough. If you live in…
