Crape myrtle bark scale (CMBS) is a serious new threat to southern crape myrtles. It threatens to turn what has historically been a beautiful, low-maintenance landscape tree into an unsightly, high-maintenance landscape tree. This nonnative scale was first detected in the United States in Texas in 2004 and was first found in Mississippi in spring of 2015. It is now well established in more than 20 Mississippi counties and will likely continue to spread. All members of Mississippi’s gardening and landscaping community need to know how to identify and control CMBS in order to help slow its spread and reduce its impact.
