Honey Bee Swarm Prevention-Why it matters.
When Spring approaches after a cold winter, beekeepers begin to think about honey bee swarm prevention. You see, the life’s goal of the honey bee colony is not to produce honey for me and you. Not by a long shot!
A honey bee colony works to make enough honey for next winter’s survival and to reproduce. Because that’s what swarming is for honey bees, swarming is reproduction on the colony level.
This is where the goals of the beekeeper and the goals of the honey bees often clash. Bee colonies want to make more colonies. The goal of the beekeeper is swarm prevention especially if good honey production is the goal.

What Is a Honey Bee Swarm?
First, lets discuss what when mean by the term honey bee swarm?
On a warm Spring day, the queen (and about half of the work force) leaves the colony in a mass. It looks like a bee tornado. The mass of bees whirls around in the air for a few minutes before alighting on a nearby tree or bush.
This honey bee swarm will hang here for several hours and perhaps until the next day. In my experience if the swarm does not leave the temporary location by 5 PM, it will stay until morning.
Then with no obvious trigger to my human eyes, the swarm of bees will take flight and leave for their new home. Where ever that may be. A lucky beekeeper will be able to catch the honey bee swarm while it is in the transition location.
Often they will regroup high in a tree top. I have lost many swarms that were 30 ft up in a Sweet Gum tree. But, sometimes I get lucky and the swarm of bees will sit down in an easily accessible location. A successful program for honey bee swarm prevention can help us reduce those “out of reach” swarms by keeping them in the hive.
A Few Bait Hives Can Help Save Swarms
Honey Bee Swarm Prevention – Control Swarming Triggers
Congestion In The Brood Nest – A Swarming Trigger
The most common condition that triggers swarming in honey bees is congestion. (or perceived congestion.) I am talking about crowded conditions in the brood rearing area of the hive. As Spring progresses and more baby bees are produced, the inside of the colony can get rather crowded. The queen may have trouble finding a place to lay eggs. This congestion in the nesting area of the hive, triggers a signal urging the colony to divide.
Perceived congestion occurs when the bees fail to spread out and make use of all room in the hive. The bees react to a congested brood area by beginning swarm preparations. The colony may have any empty super of drawn comb on the hive. Yet, the bees feel crowded if they fail to extend the brood area.
Give Bees Enough Room to Grow
One method of swarm control is to remove this congestion trigger. Well before the colony becomes over-populous, a beekeeper adds another super box. This extra space gives more “elbow room” for the bees. Thereby giving the queen more room to lay and spreading the population out. This honey bee swarm prevention technique relies on action by the beekeeper before the bee population grows.
Especially frustrating for a new beekeeper, a super box with foundation is not as effective as drawn comb. But, you have to use what you have so get that extra space on their before the bees need it.
Opening Up The Brood Nest
A more advanced method is to manipulate frames within the existing colony. The beekeeper spreads out the frames containing young – making the “nursery area” larger. The brood area is “opened” by adding a frame of drawn comb between frames of brood. If the colony is building fast, you may add more than one frame. Similar techniques include: the Demaree Method and Checkerboarding.
I do not employ either of the above methods. In the past, I had too many hives and it takes a lot of time. A beekeeper using this method should be experienced to prevent causing bigger problems. This method requires proper timing and enough nurse bees to keep all the young warm and fed.
Older Queens Increase Honey Bee Swarms
Queen honey bees can live for several years. However, all beekeepers know that it is unusual to see a queen in a production colony that is over 2 years old (or much less).
Research studies have shown that a colony with a queen 2 years old is much more likely to swarm– than a colony with a young queen.
For this reason, many beekeepers re-queen their colonies each Spring. Honey bee swarm prevention improves with a young queen in charge.
Why? Most likely this is due to the diminishing pheromone (chemical messenger) levels in old queens and reduced egg laying.
If a colony with an aging queen swarms, the original colony will produce a new queen. The swarm often re-queens itself soon after reaching its new home. In this way, both colonies are productive and ready to grow.
Using The Delay Tactic For Honey Bee Swarm Prevention
A couple of weeks before a honey bee colony swarms, they will begin the process of making a new queen bee. This new queen will develop inside an easily recognized peanut shaped cell. Before it is time for the new queen to emerge. The swarm will leave the hive. It is a popular technique among beekeepers to remove these queen cells.
The queen cells are moved to another hive (that needs a queen) or put with other bees into a new box. Or the beekeeper can simply cut out the queen cells and discard them. This is only a delay tactic and is often a very poor honey bee swarm prevention plan.
The colony will select more young larva and begin the process again. The beekeeper has not changed the mind of the colony-just slowed down the process. It might work sometimes. This tactic may keep a colony from swarming until their reproduction urge subsides. Once Spring passes, (or your build-up time of year), bee colonies will have less of an urge to swarm. However, you must get every queen cell, if you miss one your colony will still swarm.
Why Beekeepers Want to Prevent Swarms
When a honey bee colony expends energy on producing swarms, it affects the size of the honey harvest. Perhaps you live in an area with no much natural nectar that swarms are not as issue. However in my region of the US, a swarm results in a major reduction in my honey harvest. Also, the requeening process is a critical period of time for the colony. Failure to requeen means the death of the colony.
Sometimes you can wrestle nature but you can never beat her. Many volumes of books have been written on honey bee swarm prevention. The numerous strategies are well beyond the scope of this post. Devise a swarm control plan, work your plan and then accept the fact that honey bees are wild animals (ok insects). You can not completely control them.
How To Keep Honey Bees From Swarming Guidelines
1. Provide bee colony with sufficient space – add space early.
2. Keep young well mated honey bee queens in your colony.
3. Delay swarming until the urge passes by cutting queen cells. This will not always work.
4. Some strategies work sometimes and sometimes none of them work

Swarm Prevention Is Something All Beekeepers Desire
The honey bees have other plans though and sometimes you can not stop the natural process.
UPDATE – It doesn’t always work !!!
When swarm prevention does not work and you are unable to keep the honey bees from swarming. What can you do ? Catch’em.
