Hi:
I have found borers on a Picea (A. Nidiformis ... I think) that a friend
brought me a couple of weeks ago !!
I have read up all I could about it (including all of Nina's old posts) and
there seems to be little I can do to erradicate them.
Half of the tree is dead (the other half looks weak) so the bark flakes off
easily. There I have found some tunels under the bark. Some of them lead or
come from a sort of oval depressions. Some of them are blocked with resin as
the tree tried to fight this off. I can only find two probable entry points:
one is about 3 mm, the other 1 mm in diameter. In only one tunel I have
found evidence of being recent.
The question is:
Should I forget about this tree? Does the tree have a chance?
I know it is hard to say, but what does your experience tell? I don't even
know if these "miners" are active or not.

I don't know if I should worry much about borers spreading. I live in a
countryside where most trees of some age seem to be affected by borers and
flat-big headed larvae living beneath bark.
