In the news today – A swarm of bees on a London shop front.
They look impressive, and their presence can be quite disruptive, but even a large swarm is actually very docile. You can walk through them without bother and even handle them.
Just remember that, while they are clumped like this they are looking for a new home. It is always better for them to be in the nice hive of a friendly beekeeper than in someone’s roof or chimney!
