woopecker = EAB?
i've been treating my mature green ash trees with an imidacloprid soil drench for a couple years now. they have shown no symptoms of EAB until just this winter when I noticed a fair amount of woodpecker damage on some of the upper limbs. I got up there with a ladder and did not notice any D holes or tunneling in the sapwood. just missing bark surrounding single holes in the tree.
could this woodpecker damage be something else?
I have noticed a fair amount of carpenter ant activity on/around these trees.
realted question -- is this new "treeage" trunk injection treatment really any better than a soil drench? how much does treeage cost?
these are VERY valuable shade trees and I do not want to lose them...
