Hello Cindy,

Those look like American dog ticks, Dermacentor variabilis (Acari: Ixodidae).  I can't be sure from the photos. You can send them to me if you like.

To preserve and protect fragile specimens, it’s always best to submit insects in a small leak proof vial filled with rubbing alcohol or vinegar (the postal service prefers you send them in vinegar). Place the vial in a small zip-lock baggie, then in a small box or mailing tube and mail to

The American dog tick is the most commonly found tick in Michigan and can be distinguished from deer ticks by the presence of white markings on the back. Dog ticks do not transmit Lyme Disease. Their bites rarely result in serious disease in Michigan, but like other wood ticks, dog ticks are a known carrier of Rocky Mountain spotted fever and tularemia. The cases of Rocky Mountain Spotted Fever reported in Michigan are rare with only 17 cases reported from 2009 to 2013. These cases have been from primarily southern counties. Also, toxins injected with their bites cause itching, fever and in some cases tick paralysis. Be on the alert for any rash, fever, nausea or muscle ache that develops after any tick bite as these can be primary symptoms of a number of tick borne diseases. Keep in mind that ticks cannot feed immediately after attaching. They require several hours to imbed their mouthparts deep enough to take a bloodmeal.

Mice appear to be the preferred hosts of immature stages of the American dog tick while the adults prefer to feed on dogs and other large mammals. Dog ticks can live for over a year without food. These ticks are most likely to be encountered in the spring and early summer along animal paths in grassy, shrubby areas adjacent to woodlots and forests. Family members and pets should be inspected daily where ticks are known to be abundant. Insect repellents may help keep wood ticks from biting, also apply duct tape around pants cuffs to keep ticks from crawling up the legs. If an attached tick is found, it should be removed by placing tweezers near the head and gently pulling it off. Be careful not to squeeze the tick as this can inject more toxins into the wound.

Best regards,

Howard
