All joking aside, these beasts are horrible. If you live in the south or anywhere far from areas hit by these bastards AND you have an ash tree, contact your extension agent (a.k.a. Mr. Kimball) or some agriculture authority in your area to find if there are ways to protect your ash tree(s) from these massive menaces.
In the Chicago burbs, the streets are bare from where they had ash trees and now they are all removed. It is really noticeable. They will have killed your tree before you even know there is a situation. You won't see them. You just know a few years later that you have a dead or dying tree.
