From the information given here, I would do a trapout. It takes time and if done properly, the remaining bees will leave the tree as well. You can also remove the funnel used in the trapout after the colony is well established in the trap....so that they can return and rob out the stores left in the tree. It takes some time for trapouts, but you will be getting some free bees. Just make sure that all of the exits and entrances are sealed off before you apply the funnel for the trapout.
