Hi Marie, Thank you for your question. There are hundreds of species of ants in Michigan. I cannot tell you which specific one you have. Our focus at Ask Extension is on plants, their diseases and pests, so I am no expert on biting ants. I could not find any research based information on how to control these critters, but I did find a couple of posts from pest management companies that may give you some good ideas for control. Please note that we do not endorse either of these companies, but I thought the information they offered might help you. Good luck.
