Ticks are closely related to insects and spiders, and there are over 20 known tick species in Michigan. Most often, they live out their lives feeding on wildlife, however, people may be bitten when they work or recreate in areas where ticks live. Ticks are most often associated with natural areas such as grassy shorelines, wooded areas, or fields near wooded areas. Ticks are rarely encountered indoors unless brought inside on the clothing of people or on the body of a pet.
Several species of ticks are known to bite people and pets and may harbor dangerous bacteria, viruses, or parasites. Not all ticks carry diseases, but tick-borne diseases like Lyme, do occur in Michigan and can be serious or fatal if not properly diagnosed and treated.
The Grand Traverse County Health Department can help assist you in tick identification and testing ticks of Lyme disease. More information can be found under “Tick Testing” below.

Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted to humans through the bite of infected black-legged ticks. Typical symptoms include fever, headache, fatigue, and a characteristic skin rash called erythema migrans. If left untreated, the infection can spread to joints, the heart, and the nervous system. Lyme disease is diagnosed based on symptoms, physical findings (e.g., rash), and the possibility of exposure to infected ticks. Laboratory testing is helpful if used correctly and performed with validated methods. Most cases of Lyme disease can be treated successfully with a few weeks of antibiotics. Steps to prevent Lyme disease include using insect repellent, removing ticks promptly, applying pesticides, and reducing tick habitat. The ticks that transmit Lyme disease can occasionally transmit other tickborne diseases as well.
More information regarding Lyme Disease can be found at both the MDHHS and CDC websites.
