Shocked pub goers rushed for cover when a swarm of around 3,000 bees descended on their favorite watering hole.

The insects landed at the Brothers Arms pub, in Heeley, Sheffield, at 1:30 pm Tuesday swarming over its walls and a patio area.

There is video footage showing hundreds of bees gathering on a white van parked outside a pub, with a loud buzzing noise filling the air as they settled on the bonnet.

Errol Edwards, 59, had arrived at the pub to meet up with some mates when he stumbled into the swarm zone.

He said: “There was a bit of a commotion and I saw people running inside – they gave some people a fright it seems.

“They had completely covered about a 20 square meter area of the pub, including the front and sides even the patio floor.”

“The bees were absolutely everywhere, it really was a spectacle.”

Errol mentioned that he was not sure about the cause of the bee swarm but suggested that it could be related to the queen bee relocating in search of a new hive.

The swarm lingered around the building for 15 minutes before moving off to Heeley Park which is next door to the pub.

Helen Strong, 31, who works at the Brothers Arms said people ran inside after the swarm arrived on the street, and shut the doors.

She said: “Everyone ran in and we shut the doors – I think people were shocked.

“Luckily all the bees stayed outside as that would have been a disaster.

“They were out there for about 15 minutes but in that time it felt like something out of a horror film.”
