I purchased four mated queens in August with the intention of splitting some of my older colonies to create four new colonies. The requeening didn’t work out so well, but eventually I think (I hope) I got one colony started up well from a split and another one requeened. The other two mated queens were killed outright and another replacement queen I picked up a week later isn’t dead, but it’s barely laid an egg and it’s currently living in a nuc box — and it looks like this:
I inadvertently created a walk-away split on July 18th when I removed some brood from an established colony to make a nuc. I would have much rathered that the mated queen I gave the bees hadn’t been killed by the bees, but that’s another story.

If we return briefly to the beginning of this story, 18 days ago on July 18th (A Requeening Gone Bad), we learn that a mated queen was added to a split about 23 days ago and five days later, the mated queen was found dead in her cage along with several open and capped supersedure queen cells. I didn’t touch the hive until today when I noticed a few bees bringing in pollen. Foragers don’t usually collect pollen unless they have a reason to do so, and that reason is usually to feed a queen bee and her brood. So I decided to take a peek inside and low and behold, I found a new queen scooting around one of the frames looking for a place to lay.

April 2019 Introduction: This is how I’ve introduced mated queens since I began beekeeping in 2010. I’ve had no problems with this method. But here are a few extra tips not mentioned in the post:
1) If using a wooden queen cage, the cage can be placed horizontally between two frames of brood so that the screen portion of the cage is facing down. I’m not sure what difference that makes, but the University of Guelph‘s head beekeeper does that and I’m pretty sure he knows what he’s doing.
2) The hive should be left alone for a least a week after the queen has been installed. Any kind of disturbance in the hive can cause the bees to reject the queen, even if the queen has already been released from the cage. I’m guilty of looking into the hive too soon. I need to remind myself that I shouldn’t go near the hive for at least a week.
As much as I would rather leave it to my honey bee colonies to make their own queens naturally when they need them, they don’t always succeed. I have requeened come colonies with swarms cells, but most of the time I just order a mated queen. Here are some things I’ve learned the hard way by letting the bees make their own queens whenever they feel like it:
1) Unless the virgin queen can mate with drones from another bee yard, it’s likely she will mate with her own siblings and produce inbred and ill-tempered bees. My queens mated well only when there were about a dozen other colonies in the area.
2) Swarms that happen later in the summer can result in two weakened colonies instead of one strong colony (assuming the swarm is caught and re-hived). While swarm colonies typically expand quickly after a swarm, they can only grow so much once the weather turns cold and are often too weak to survive the oncoming winter.
3) Whether through supersedure or swarming, the natural process of requeening usually results in a 2-4 week period of reduced or even zero brood production, which again weakens the colony no matter when it happens. A weakened colony can be propped up with brood from a stronger colony, but not all hobbyist beekeepers, especially starting out, have that luxury. That being said…
The following video demonstrates my method of installing a mated queen and checking on her to make sure she’s been released from her cage and then checking on her again to make sure she’s laying. I don’t have years and years of experience installing mated queens, but I’ve followed this exact method about a dozen times since 2010 for myself and friends, requeening and starting up new colonies from splits, and it works.
June 2019 Introduction: I’ve deleted some bits from this 2015 post, but instead of rewriting the whole thing, I’ll just tell you what happened in the end.
I purchased some mated queens from a local breeder who has virtually bred out what some would describe as “blonde bees,” or lightly coloured bees, usually honey bees of Italian stock. His bees are what some refer to as “black bees,” or honey bees of mostly Russian stock. And here’s the deal with Russian honey bees (to quote from a PDF article published by North Carolina State University):
“Requeening Italian hives with Russian queens can be difficult, and many beekeepers lose their newly introduced Russian queens. Russian queens have a different ‘odor’ than Italians, and parent colonies must become acclimated to this odor before they will accept the newcomers.”
And that’s exactly what happened with this requeening gone bad. My Italian colonies simply did not accept the Russian queens. All but one of the queens were killed outright and the colonies went on to make a new queens and were broodless that whole time and it was a headache I could have done without because it basically left me with a bunch of weak colonies. I wrote more about this in my post, A Stubby Ragged Queen. The moral of the story is, be cautious when installing a dark queen in a colony that previously had a light queen. If I do it again, I’ll cage the queen for a week and manually release instead of allowing the bees to chew through the candy plug to let her out. See How To Install a Mated Queen for more info.
I added a caged mated queen to three splits last weekend. I checked on them today and found supersedure cells in all three hives. Here’s a sample (and if you click the image to enlarge it, you can easily see the larvae swimming in royal jelly):
Here’s what I found in…
Split #1: The new queen DEAD inside her opened cage and several capped supersedure cells.
Split #2: The new queen alive and one supersedure cell full of royal jelly.
Split #3: The new queen M.I.A. (possibly dead) and several capped supersedure cells.
I say supersedure cell, but I suppose the more accurate term is “emergency queen cell.” Supersedure cells are created when the queen is failing but not yet dead, whereas emergency queen cells are created when the queen is suddenly dead. I think. Maybe. The difference seems so minimal to me, I always say supersedure. To make it more confusing, the presence of swarm cells usually means the bees are going to fly away with their old queen, but presence of supersedure cells means they’re simply replacing a failing or dead queen. That’s how I sort it all out anyway.
