This may have been discussed earlier. A great temporary fix for a queenless hive is Temp Queen (used to be named Bee Boost) queen pheromone. I always have several tubes in the freezer to use when I need it. It lasts a very long time; enough time for you to wait for a new queen to be shipped. Several times, I've used a tube for a week or so, put it in the freezer and used it again another time. I wouldn't be without it.
