my mother in law has a over grown sea grape in her yard. and i was cleaning it up for her to look more like a tree instead of a mess of branches. anyway i have it all trimmed up an i started to pull out the dead & not wanted branches from the middle of the plant and out comes 1,000's of Carpenter ants. is the plant a goner now or can it be saved? if it can be saved how do i get rid of the ants?
