Every year I receive several calls and receive samples of boxwood leafminers. I was just reminded this week as I was walking past my boxwoods that now would be a great time to spray to kill the adult flies. This should be timed as the new shoots begin to appear, which is now at my house. At other times during the year, you can treat with a soil drench or soil injection using a product that contains imidacloprid. For more information about boxwood leafminers, see the NCSU publication provided below or call your local Extension Agent. http://www.ces.ncsu.edu/depts/ent/notes/O&T/shrubs/ort016e/ort016e.htm
