For information on ticks and tick-borne diseases, please visit our webpage Ticks and Tick-Borne Diseases webpage

Ticks found on humans can be submitted to The Connecticut Agricultural Experiment Station (CAES) for identification and/or testing through the NVHD. CAES will identify all ticks, but only test those that have ingested human blood. Please bring the tick to our office in a sealed bag or container. NVHD will contact you with your results. There is a $5.00 fee per tick or individuals can submit ticks on their own by completing the CAES Tick Submission Form and mailing the tick directly to:

The Connecticut Agricultural Experiment Station
Tick Testing Laboratory
Jenkins-Waggoner Building
123 Huntington Street
New Haven CT, 06511

Preparing the tick:

  • Do not place the tick on tape.
  • Ticks should be placed in a crush-proof container, but if one is not available a sealed plastic bag will suffice.
  • Do not package the tick in glass or in other fragile containers.
  • Do not package the tick with any objects. This includes paper towels, cotton swabs, plant matter, bandages, or any other materials.
  • Do not place the tick in any solution. This includes substances like water and alcohol. All ticks should be submitted dry.

Preparing the envelope:

  • The crush-proof container housing the tick should be tightly sealed and packaged in a padded envelope.
  • If a padded envelope is not available, a small sheet of bubble wrap can be added to a regular envelope to help protect the tick from being damaged.
  • Please request the mail carrier to handle the envelope containing tick manually and not through a machine. “Please hand sort” can be written on the envelope to help achieve this.
