A Bee or Not a Bee!
The first thing to do if you suspect you have a swarm is to find out if they are honeybees or something else!
Only Honeybees will swarm and are not as common as bumblebee or wasp's nests are.
Honeybee Swarms arrive as a flying cloud which will eventually settle either hanging from a branch of a tree or bush, a fence post, washing dryer or any other convenient structure such as walls, eves, sheds etc. They are not generally aggressive during swarming but it is best to give them a wide berth until they have moved on or have been removed by an experienced person.
We can only help with swarms of honeybees, if you are having a problem with one of the other species please see below for the Local Authority Pest Controllers.
Below is a simple identification guide:
