White oak bugs and trunk damage
Tree identification said it is a basket oak.
Location: North Texas
There is trunk damage shown in pic and tiny black bugs going up and down trunk to the soil. It looks as if they are carrying tiny white or grey specks.
I could not get a good picture of the bugs because they are so small.
What, if anything should I do to treat?
Tree is approx 14 feet tall, planted about 4 years ago, and has some crown die back this year (suspect do to a bad ice storm in January. Prior to that, tree was doing fine.
