What is the Tick Blitz?


We are conducting a Tick Blitz in the Hudson Valley and Central regions of New York State to understand where different tick species are present in the state and track their northward expansion.

How Does it Work?

  • Individuals who register to participate will attend online and/or in-person trainings to learn how to properly and safely collect ticks in their community
  • Volunteers will receive a kit in the mail or pick one up at their local Cornell Cooperative Extension office. The kits will have everything they need to collect and return tick samples and protect from tick bites.
  • Volunteers will collect ticks at a dedicated location of their choosing at least once between June 12 and June 23, 2023
  • Collected ticks will be mailed back to Cornell University where they will be identified by our team of entomologists. Results will be made available online and shared with event volunteers.
