I'm sorry. That sucks. We just had to take down our 80 year old ash in our front yard. It was the most beautiful tree on our property, but it dropped dead for no apparent reason like 5 other ashes on our land. We don't have the ash borers because the trees were checked out by an arborist. Ours have a vascular disease brought on by stressful conditions (long drought followed by couple years of too heavy rainfall). Ashes are in serious trouble all over the country. They are going the way of the elm. There is a big push to try to save the ash in our area because there have been so many casualties.
Call an arborist to see if they can help you save your trees. We waited too long and couldn't save ours. Good luck.
