Ticks are closely related to insects and spiders. There are over 20 known tick species in Michigan. Most often, they survive by feeding on wildlife. 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-related diseases such as Lyme disease do occur in Michigan and can be serious or fatal if not properly diagnosed and treated.
Tick data for reported ticks are available on the MiTracking data portal.
