Now established in almost every Michigan county, the blacklegged tick is the most significant public health concern in the region. Found predominantly in leaf litter, low forest vegetation, and along wooded trails, this species is the primary vector for Lyme disease. They are often smaller than other common ticks, making them difficult to detect.
Widespread throughout Jackson’s grassy fields, open meadows, and forest edges, this is the most frequently encountered tick in Michigan during the summer months. Readily identifiable by the white markings on their backs, they are known to bite both humans and companion animals and can transmit diseases such as Rocky Mountain spotted fever and tularemia, though cases remain relatively rare in the state.
An aggressive biter that is increasingly found in the grassy and wooded areas of southern Michigan. The adult female is distinguished by a single silvery-white spot on her back. Bites from the Lone Star tick are notably associated with the transmission of Alpha-gal syndrome, which triggers a severe allergic reaction to red meat.
Tick activity in Jackson, Michigan, is heavily dependent on temperature and humidity. Unlike mosquitoes, which require standing water to breed, ticks require high humidity to survive off their hosts and prevent desiccation.
The transition from late winter to early spring marks the beginning of tick season. As soon as temperatures consistently rise above freezing (typically around 40°F or 4°C), adult blacklegged ticks that overwintered in the leaf litter become active, seeking a blood meal.
Late spring and early summer bring peak activity for the American dog tick and the nymphal stage of the blacklegged tick. The nymphal stage is particularly hazardous; because nymphs are roughly the size of a poppy seed, their bites often go unnoticed. Summer humidity supports sustained activity in dense vegetation.
While harsh Michigan winters force ticks into a state of diapause (dormancy) under the snowpack and leaf litter, mild winters or early thaws can lead to an unseasonably early emergence, extending the window of risk for local residents and wildlife.
