Pest controller Gary Wilkinson, of Northamptonshire pest controllers Pest Professionals, who found the nest, said: "It's an impressive wasp nest alright - much bigger than a barrel. Normally we get called in at the first sign of wasps causing a problem to people. This community has been allowed to go about its business undisturbed for a whole summer season. Although you wouldn't want it in your own loft, you have to say it's a very impressive and in its own way a very beautiful thing." Carcasses of hundreds of dead wasps found next to the nest indicate that the colony was created by the common wasp (Vespula Vulgaris).
