Black Carpenter Ants Swarming With The Queens

After the rainstorm today on the farm I went out to check the blueberry plants I potted this month.  They looked good, and were glad of the rain. On the way back to the house I noticed a swarm of ants in the spruce tree.  I have been taking photos of the hole in this tree for a few years now and video sometimes.  Birds have nested in it, ants lived in it and have infested this tree.  The sap flows freely and is useful also.  I like spruce gum!
