I had the same thing last year this is what I did. i bought a queen put her in hive they balled her and killed her. so i bought another queen and I shook out all the bees about 50 yards from hive. Yes I know people say it does not good cause the know how to get back to hive. I did it anyway. Then I took the new queen and a frame that had honey and pollen in it and built a 5' x 5" push cage out of aluminum screen and pushed it into comb and put a rubber-band around frame to hole it into place and put queen inside it, this was so she could start laying eggs and move about in that area. Left her in there 3 or 4 days came back released her and watched them chase her into corner, the bees would go and touch her and turn around one after another...problem solved... no guarantee, but it worked for me and a few others that I know of
