Oak Sap and Insects
Name: Lori S.
There are two areas on my oak tree that are draining sap that smells like rotten
fruit. Also, there are numerous bugs on these sections of the tree (ants and some big black
flying bugs with white circles on the backside). Are they harming the tree? And what do
I need to do to get rid of the bugs, and help the tree?

Seems that treating the tree wounds to prevent the sap leakage would be
useful since the insects might transmit disease to the tree.
