That is sad LazyBkpr. I know I have gotten to a beetree too late, they were already dead or gone, and their comb was infected with European Foul Brood. I brought the stump home to make a table out of, used some of the comb for swarm traps and young hives, the African hive occupied the tree so I moved their brood when I kicked them out, and yeah, Riverbee diagnosed the EFB for me in my hives the next year. After removing carpenter ants from it 2 or 3 times I put it at the curb for the city truck with the giant jaws. All the comb was gone and torched already....
I caught my abscond - no queen cells or swarm cells in her hive, the workers that came home tended the last of the capped brood and did their best to handle the SHB infestation.
But she lit in my swarm trap on the old chevy. I haven't opened the lid yet, switched them to a feeder lid and put a jar of syrup on it. Knew it was occupied when they threw the yellow jacket out.
