We get bees swarming in our office porch every year. No idea why. No-one has ever got stung we just have to use the back entrance for a while. Every time it happens the local beekeeper comes out and collects them and gives us some free jars of honey.
One year something went wrong and they got inside the roofspace and could not easily be retrieved and by the time NHS estates rumbled into gear to take the plasterboard down it was quite incredible how many there were. The whole porch roofspace was alive and moving like something out of a horror movie.
It is pretty fascinating though. I loved that video of them all trooping calmly into the hive up the white sheet. When she said 'and now put them in the car' I did think that was brave driving with a box of bees wrapped up in a sheet. I thought of how DH and DS react if even a fly gets in the car and decided they would not make it as beekeepers.
