What is a false swarm?
A false swarm is when a part of the hive swarms without the queen.
Name two swarm control methods

Mention one risk involved in trying to allow colony to raise own queen
Virgin queens will need to be mated, which has a 2-3 times higher cost
If a queen is unable to fly out for mating due to prolonged bad weather
queen will start laying unfertilized eggs
Two weather parameters that are important for mating flights
