Swarm season will be soon upon us. In central and south Texas, it's not unusual for swarms to be active from early spring to late fall, while different natural flora bloom throughout these months. Some regions will have more of a prolific nectar flow season than others around the same time of the year. Our big nectar flow is mainly in the spring, followed by a small nectar flow in the fall.
Swarms tend to happen with the onset of the nectar flow. There are many other reasons why swarms occur throughout the year. It could be that the colony has outgrown its space, congestion, lack of ventilation, lack of laying space, strong colony, disease infestation, and or reduced queen pheromones.
When colonies swarm, roughly three-fourth of the bees along with their mother queen will leave the hive. Whereas each individual honey bee, of any caste (worker, queen, drone) works for the totality of the colony, swarming equates to its reproduction, the birth of a new colony.
Did you know that scout bees (older than the foraging bees) are the ones to search for a new home for their swarm?
PachaMama Bee’s services include removing colonies and swarms from unwanted places. Whether they've been established in some structure for years or recently perched on tree branches, we see how quickly swarms can establish themselves into cavities of homes just within a few days of arriving. They quickly build fresh comb and the queen starts laying; foragers are already coming back with pollen and nectar. They do not waste any time making themselves at home in their new location (and getting ready for the next big season, so they can survive winter).
Though we cannot alter this biological imperative, there are ways to work with Mother Nature. Enter swarm management. To begin, the beekeeper must know his/her goals with the hive. For PachaMama Bees, the goal is to propagate our colonies. Loosing seventy-five percent of a colony’s bees due to swarming, can be a bit of disappointment. But if you ever get to see a swarm happen in action, sit back and enjoy it. It’s a beautiful thing.
In short, here’s what we do to manage to prevent swarming.
Set up swarm traps
Clip the wings of queens
Add more brood space to colonies
Cut queen cells
Split colonies with new queens
We prepare way ahead of time. Securing spring queens by ordering in the fall. Fall is also the time we build up inventory, assemble equipment, and do a bit of equipment painting. We assemble and make ready nuc boxes.
Inside the hives, we make sure that our colonies have plenty of food resources to make it through winter. We'll supplement as needed by feeding by sugar water and pollen patties.
In the first months of the new year, hive inspections are revealing our colonies have plenty of food resources and are at full strength. Proactive measures taken in the fall have paid off; not to mention checking and treating for varroa mites.
In early spring we'll start looking for swarm queen cells. Swarm queen cells are usually located at the bottom of the comb. But they can be found in other spots in the comb as well.
If we find queen cells in a hive, we'll cut most of the queen cells and leave only the largest two queen cells in the comb. Then take two frames of brood with nurse bees and a frame of honey/pollen. These frames along with the queen cells in the comb are placed in a nuc box. The original hive is moved away to another spot in the yard. The nuc is placed in the spot that the original hive was located, with the same entrance orientation. This is because the foraging force of bees will help the nuc grow, reestablishing themselves in their new home while the original hive will rebuild its population on their own with the help of the nectar flow. Later in the season, we’ll requeen the older queen from the original hive.
We perform this action over again with the rest of our apiaries with newly mated queens. Some colonies will requeen themselves without our intervention. While there are many methods of hive splitting, we mainly focus on colony splits with a mated queen. Strong colonies are chosen for hive splits. Sometimes we’ll get two or three hive splits from one colony- and that is why it’s so important to manage for swarms.
