Answer: Unfortunately, it sounds like your trees are suffering from an infestation problem and it is apparently spreading. You might want to take a sample and possibly a photo to your county extension (473-2540) for a specific identification of the problem and recommendations for what to do about it. If a chemical treatment should be necessary, they will be able to give you the most up to date recommendations for what to use and how and when to treat it. I'm sorry I can't be more specific.
