Greetings fellow gardeners! Something appears to be killing a grapefruit tree on some land I own in Florida. At the end of some branches it looks like something is causing the bark to strip off. While I was taking pictures to show I noticed some huge red ants and smaller but longer gray looking ants crawling on the branches. Today I was out looking at it and some bark was gone off of one of the main trunk/branches of the tree. Also, 1 detail that may help you help me is that I removed a few palm trees that had been blocking some sunlight to the tree. The parts of the tree that had be getting the shade turned a yellow green but seem to have come back.

Thanks!
