Thanks John Bunker for your post. I hate to admit it, but I had some wasp
and hornet killer that was left on an old boat we'd bought, and after trying
and trying and trying to get to the borer in our tree with digging it out,.
I finally just sprayed a blast into the hole. I prefer to be organic, but
the thing was going to kill my tree! And since then, that was several years
ago, I haven't seen another borer, but I worry about them now that I have
young trees! So I appreciate your post and I have some old latex and joint
compound, also wood chips, so all the ingredients to put your suggestions to
work.
