I have had 7 of my pine trees die in the last 2 years. It appears that
there is some insect that looks like a wasp that is all black that
bores into the tree and cause a lot of pitch to flow down the bark.
Sometimes the spot is 6" by 3 feet. These trees are in northern
California. Could these be pine beetles? Is there anything I can do
to save the other pine trees near them?
