Even if you add supers in time, you might still have swarms, since the colony's instinct is to swarm and create more colonies. An exclusive queen keeps calf production below and honey production above. Making adjustments to the area of the breeding nests is the earliest anti-swarm tactic in spring. Make sure your nests and hatchling nests have a generous amount of space and sufficient airflow.
By inverting the position of the brood boxes and adding an additional box, if necessary, space is created in the brood nest and the colony is encouraged to expand upward rather than swarm. Stacking superobjects on top may not be enough, although it can temporarily ease congestion and help in part. Leaving a colony without superheroes during an intense flow of nectar is a foolproof way to fill the brood box with nectar and prepare a swarm. I have five buds that will turn into full hives next week and I hope they will give me honey to summer.
Read your thread and, to reduce the swarm, you need to leave more space in the hive and give them work to do. Due to the panic caused by the virus, Canada has banned the importation of seed colonies, and there is great pressure on local beekeepers who produce and sell seeds made from their own seeds. Something I forgot to mention is that when I do the division, I remove it well so that the adult bees don't return. As a superorganism in which each member plays a role, it is important that there is work available to all bees at every stage of their lives.
While the desire of bees to multiply is natural, letting bees reach this point is not considered a good practice because it represents a risk to the public, bees, other beekeepers and the biosafety of honey bees in their country. If beekeepers don't notice the signs and don't react accordingly, honey bees will naturally multiply in swarms. This time frame offers beekeepers some opportunities to reduce the likelihood of a swarm or to avoid it completely. As soon as I see that there are bees in the migratory zone piling up and doing nothing, or even if the honey seems to be full of bees, I will think about doing a preventive division to control swarms.
This occurs when the entire colony leaves the hive for various reasons, such as bad weather, starvation due to lack of resources, but more commonly due to the infestation of pests and diseases that have made their space uninhabitable. While this is happening, I like to use a single breeding box with only one super honey collector, however, I try to prevent the super honey tank from filling up with bees. However, older queens are not guaranteed to form swarms, and they have been known to swarm newly made cores and bundles. If you find a cell with a rough opening at the bottom, it's a sign that a queen has already come out of that one.
