he nest measured 6ft by 5ft and was found in Southampton, Hants.
The infestation was discovered in a chimney stack before being destroyed by Sean Whelan, a pest controller.
Mr Whelan said: “It was scary as hell but it is what I am trained for – I just pulled out my iPod and listened to ‘Bat Out of Hell’ to get me through the job.
“I killed all the wasps but the nest is still in the attic where it will be left to disintegrate.”
Experts from Oxford University have verified the nest is Britain’s biggest ever and the biggest anywhere in the world in the last 50 years.
David Baldock, from the Bees, Wasps And Ants Records Society, added: “It is certainly an enormous nest and certainly a record. I have never seen a nest that size.”
The largest nest ever recorded was found in New Zealand in 1963 measuring 12ft by 6ft.
