Tick Information

There are 13 known species of ticks in Vermont. The most common species is the blacklegged or deer tick, Ixodes scapularis. Dr. Trish Hanson, working with the Vermont Department of Forest and Parks, did a study of ticks on household pets submitted voluntarily by veterinarians. Her study demonstrated that blacklegged ticks were well established throughout Vermont in 2003, although the northeast area of Vermont had more winter ticks, a tick commonly found on moose.

The Vermont Agency of Agriculture has surveyed for ticks and tested blacklegged ticks for diseases. These studies have documented the density of ticks and risk for contracting tick-borne diseases in the state. Lyme disease and anaplasmosis are diseases caused by 2 types of bacterial organisms, Borrelia burgdorferi and Anaplasma phagocytophilum. A third disease, babesiosis, is caused by a microorganism called Babesia microti. As of 2016, it appeared to be showing up in Vermont. Antibodies to a fourth tick-borne disease, Powassan virus, were detected in deer during a study of antibodies in deer serum looking for other diseases carried by mosquitoes. The Vermont Department of Health has also documented cases of ehrlichiosis, another bacterial illness carried by ticks.
