You need to go out and get yourself a good coon dog!
Hey CB375HH, you need to get some Conibear traps if you really want those coons gone. I have also heard of peeple calling in coons at night using a giant spot light with red lens cover and a rimfire rifle (22 LR or 22 MAG) or shotgun. Here is a link to a site where you can pick up some of the traps.

I found all the rules and regs on fur harvesting on the Michigan DNR. I have not had a chance to review them completely but I figured that this would be a good reference on trap sizes, locations ...etc.
