It was recently reported that there were confirmed hits of Emerald Ash Borer (EAB) in Lake County. This insect ONLY affects ash trees, so all other species are safe. There are preventative treatments listed on this site that you can use to help your trees. If your tree is already affected, there are options to consider. If the tree's health has already started declining, it may be too late for treatment. Otherwise you can contact lawncare or tree services to see what additional treatments they can offer you. If you would like information in general about this insect, you can visit this website or call the Extension Office for more information.
