How can I keep a swarm

[m100]

Also will people please stop advocating killing drones. Drones are natures way of ensuring proper mating of queens, added to which they are good for the colony in ways we just lack understanding at the moment, but would not be tolerated in numbers if they weren't. We allow all our colonies to produce as many drones as they wish which means other beekeepers in our area benefit, lots of drones means survival of fittest. We also get lots of honey, just had our first lot from the hawthorn which flowered with abundance and was covered by the bees - light and not overly sweet. Prepped as cut comb!

While drone are the way to propagate wanted genes, and they appear to make a colony more content, their longer time spent as sealed brood increases varroa numbers massively.

Drone culling is a well recognised method of controlling varroa mite.

Lots of drones from dubious sources crossed with imported queens results in bees that don't deserve to live because they often produce bugger all surplus, succumb to nosema and are often impossible to manage due to their propensity to sting.
