You will have to find the old queen and kill her or else the workers will kill the new queen. Everyone has their own favorite method of requeening so here is mine. I find and kill the old queen and remove her from the hive. I then take the cork out of the candy end of the queen cage and place the cage face down on the topbars. Invert the inner cover on the hive to make room for the cage put the cover on and do not disturb for 4 days. Then check to see if the new queen has been released. If she has then check the hive to see if there are eggs present. If you find eggs close the hive check again at your normal interval for working the hive. at this time you may wish to locate the queen just to see her. If the queen has not been released, observe how the bees are acting toward her. If they are still biting the cage and acting aggressive then look for queen cells. The bees may be rejecting her and are trying to raise they own. If they are feeding the new queen through the wire of the cage, they are probably accepting her and you can release her directly into the hive. If there is no nectar flow on feed 1 to 1 syrup to enhance acceptance. Also when I receive my new queens I sometimes place the new queen on top of a super that has a queen excluder under it. I leave her there for the young workers to feed and keep warm for a few days before killing the old queen. I have found that sometimes helps if I'm having trouble getting a queen accepted. Like I said everyone has their favorite method and you will probably hear a lot of them. Just pick one you like and try it. Most will work this time of year. Frank Humphrey
