Help needed for 40 year old silver maple

Asked July 16, 2020, 5:46 PM EDT

I had a tree company over to trim dead branches off of my 40 y/o silver maple in the front yard. After the trimming was done I received a diagnosis that the tree is not well due to carpenter ants and fungus that have infected the core/heartwood. The arborist stated that there is no solution to this problem and eventually the tree will probably collapse or die due to this condition. My question is this: Is there anything I can do to help heal this tree or it truly hopeless? Thanks in advance.

Here is information on Carpenter ants:

If the ants are boring into the maple tree in which sawdust is noticeable, then they are likely carpenter ants. They nest in the heartwood of the tree, which is likely decayed because carpenter ants do not nest in living, healthy parts of a tree.


Nor do they do not feed on or kill trees, but their excavations might cause structural weakening which makes a tree more susceptible to breaking. However, many trees can survive years with carpenter ant colonies in the heartwood. There are insecticide sprays that can eliminate the ants by spraying it into the tree if you can find the nest entrance.


For the other diagnosis, 'fungus' is a broad term so we would need to know what the fungus is and what the signs are. If the arborist said there is no solution, then he should be able to provide what the fungus is. There are several problems that affect silver maples so it would be helpful if you provide more information.
