I just moved into my grandmother's house. She has a mature pear tree that has not been cared for for years. There are many dead branches. I did some pruning and found carpenter ants living in the thicker branches close to the trunk. There are ripe fruits on the tree. Lots of ants in the trunk and lots of sawdust. How do I get rid of the ants? Is the fruit safe to eat? Can I save the tree? Thank you in advance! Jess
