There is really nothing you need to do for this situation. The ants are not feeding on the wood, and not harming the tree. It may be an indication that there is some rot somewhere on the tree. But older trees often have areas of rot. Sometimes this can be an indication that the tree is a hazard tree about to fall, but often it is a small area of rot that the tree has sealed off and is living with.
You may want to consult an arborist to see if the tree appears ready to fall and is a danger. It is recommended that you consult an ISA-certified arborist. Go to to find a list of certified arborists in your area.
