Swarm Control
Pagden method with no increase
Stage 1
The swarm with the original queen is caught and put into a new box on a new stand with OMF and roof.
The original brood box now contains all the brood with queen cells.
Stage 2
After allowing the swarm to settle in the box, this new brood box is exchanged for the original brood box containing the queen cells.
All the foraging bees on leaving the latter return to the original site and augment the swarm.
Stage 3
When no increase is wanted the brood box with the queen cells is left until all brood has been sealed.
All queen cells are now destroyed and the box placed above the supers and left for 2 weeks until all brood has emerged. The box is then removed.
Pagden method with increase
If an increase in the number of colonies is required, then a choice can be made after all the brood has been sealed.
If only one new colony is required then all queen cells should be destroyed except one. The brood box can be left on its stand and the new queen allowed to emerge and mate. New brood should be seen about two week after emergence.

If, however, more than one colony is required then the brood box can be divided in two or three nucs. For this a split board is required with 2 or 3 entrances () cut in its rim; also 2 or 3 made-to-measure crown boards are needed. 10 frames from the colony are divided accordingly (3 : 4 : 3) so that a well formed queen cell is in each nuc. In these two cases it is necessary to ensure that there is no bee space on the underside of the brood box, and that a divider is accurately made so that no bees can pass from one nuc to its neighbour.

In spite of ones best efforts the emergence of swarms and casts is a constant threat during the summer season. It pays to be prepared with a well thought out strategy of what to do when swarming does occur or when queen cells are found during a routine inspection. It is essential to realize that the bees will swarm as soon as the first queen cell is sealed, therefore action must be taken before this point is reached. Essentially the colony is made up of 3 parts: i) the queen, ii) the brood and nurse bees, and iii) the flying bees. Effective swarm control then entails the separation of one of these parts from the other two.

Three scenarios are listed below:
1. the swarm is seen to emerge from a colony. The swarm and queen cells are treated by the Pagden method.
2. unsealed queen cells are found; it is assumed that the colony is still intact but
i) the queen can be found or ii) the queen cannot be found.
3. sealed queen cells are found during a routine inspection; it can be assumed that the colony has swarmed.
