Generally, all of these tick species inhabit the same types of environments within our state. They are commonly found in wooded, brushy areas such as forests, and they can even be found in grassy fields or yards. In order to prevent getting bitten (and potentially contracting a tick-borne disease), always take the proper precautions when spending time outdoors in Tennessee.
