Ticks are common throughout the Lakeshore with a high population located on North Manitou Island. The most commonly found tick at the Lakeshore are the American Dog tick (Dermacentor variabilis) and the Black-Legged tick (Ixodes scapularis), also commonly known as the Deer tick. The Black-Legged tick population has gradually increased in recent years and is known to be a vector of Lyme disease.
Lyme disease is caused by the spirochete bacterium Borrelia burgdorferi. Prompt removal of ticks is an important step in preventing diseases. In most cases, according to the Centers for Disease Control and Prevention, a tick infected with Lyme disease must be attached to its host for 36 - 48 hours or more before Lyme disease can be transmitted.
