A simple way to collect a swarm. If you’re nervous and the bees are strangers to you, you may want to wear protective clothing. Usually as a swarm the bees are at their most docile stage – though , not always.
I remember once when called in to remove what appeared to be a swarm sitting on a branch, I approached without any protective gear on. Once I shook them off the branch into a container , however, they attacked me and caused many a stinging reaction through the entire swarm.
The reason for this, I found out later was that they had been removed with an insecticide aerosol from a cupboard . Consequently, they were naturally upset with having been turfed out of their home without the opportunity to prepare for evacuation such as feeding on the available honey stores. No wonder they were upset. So, although it is true a swarm is usually docile, it pays to take precautions if you’re unsure where they came from.
