Recognize this boring insect?

    Here is a photo of a boring insect attacking a burford holly. These guys have gone systematically from one holly to the next, never attacking two at a time that we know of. They are actually building a tunnel of mud (or possibly it's saw dust from the plant) up the side of the trunk like a termite would do and they're eating it from the inside out.

    What is it? And more importantly, how do you treat it? Will the systemic pesticide "Merit" work on these guys?

    It might be flat head or twig Bores. Sorry. It is too late for Merit. Cygon If you can find it might be the only thing still around that will get them. If you can find some, add Hort oil as a sticker for the bark. The tree Huggers have gotten all the good Bore chemicals. At one time Lindane would have been the answer. Orthene might work but it is not a true systemic and you would have to give repeated treatment to be sure. It might be wise to treat all plants in the area with Merit as a preventive. Be sure to prune all infested twigs and burn them.
