Our laboratory staff are checking yards for ticks to better understand what factors affect whether ticks are in a yard. To learn more about the study, visit this page. Currently, we are enrolling households from Pacifica and Hillsborough for these backyard checks. Please fill out the form below if you are interested. Tick checks of yards will take place between November 2022 and March 2023. You will receive a follow-up call or email with the dates that we'll be in your neighborhood. Thank you for your interest!
