Here is a link to help our consumers in Michigan find out if the company they are currently using or considering, is licensed in the proper categories to legally work in the State of Michigan.  Please check it out before letting anyone apply pesticides of any kind on your property.  If they are licensed in the state, then you also know that they’re insured properly as well.  The State of Michigan will not issue a license to a firm that does not present proof of current insurance coverage with required limits.
