upon inspection take inventory of the numbers......if they are fairly low and have more comb then bees your setting up another infestation of wax moth larva. You can pull comb and make a make shift divider to make a smaller box or put them in a 5 frame nuc reducing comb to police and space to work. The wax moth want kill them but they make an over all mess add stress and could make them abscond. I like 7 to eight frames of bees mid day while all the foragers are out on a 10 frame box. Honey supers are a little different but even then to little bees to do police work is a problem.
Edit: Root cause was most likely a very old hive location varying populations and to much comb vs current population. After the summer solstice all hives; especially wild hives, slowly but surely ramp down growth and bee numbers. The queens will slow down laying rates and eventually the biology and metabolism of the new bees changes over to winter bees........and they live longer.
