Answer: I don't know whether borers are infesting your entire neighborhood or if your landscape is just an isolated incident, but borers are really difficult to control, especially when damage is already present. I can only suggest you contact your local county cooperative extension office for suggestions. I don't know which county office is closest to you so here's a website: http://extension.osu.edu/counties.php
Scroll down until you find your county and then contact the agents there for some control measures. Best wishes with your trees!
