October Glory Maple Trunk Damage: Borer or Fungus?

Borer: Insect larvae tunneling. If hole visible, insert wire to kill.
Fungus: Damaged area colonized by fungus.

Sawdust-Like Growth, Bark Eaten Away

5-year-old maple has 4-inch irregular patch of sawdust-like material on trunk. Underneath, bark is eaten into but not through to core.

Clean area, monitor. If borer hole present, probe with wire. Keep tree vigorous.
