The five most common ticks in Michigan are:

• Dermacentor variabilis (American Dog tick)
• Dermacentor albipictus (Winter tick)
• Ixodes cookei (Woodchuck tick)
• Ixodes scapularis (Black Legged tick)
• Amblyomma americanum (Lone Star tick)

American dog tick
The major vector of RMSF in Michigan is the American Dog tick, D. variabilis. It can also transmit the bacteria that causes Tularemia, and can harbor the Ehrlichiae bacteria.

Dermacentor albipictus is common on deer and elk in northern Michigan. Hunters may find these ticks on animals they have shot, when the animals are being field dressed or when they are at slaughter or being processed for taxidermy purposes. They are uncommon on people and not known to transmit disease.
