Giant Nest Crafted By 10,000 Stinging Wasps Found In Northamptonshire Loft

'You have to say it’s a very impressive and in its own way a very beautiful thing'

A pulsating alien egg? Ikea’s latest paper lantern shade?

Alas, it is the painstaking work of 10,000 stinging wasps.

This mind-bogglingly large sphere was found in an abandoned loft space in Northamptonshire, that had been unoccupied for several years.

This giant nest was built by up to 10,000 stinging wasps 

The nest is a rarity not only because of its mammoth size, but because the wasps built an intricate tunnel from the nest to the outside.

It was discovered by pest controllers treating an established woodworm problem prior to the new owners moving in.

Pest controller Gary Wilkinson of North London based Pest Professionals, which 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).

However people in the UK have been asked to be on the lookout for the larger Asian Giant Hornet which has been heading north across Europe.

The Asian Hornet is even more aggressive than the common wasp, has a darker thorax and its stings have caused a number of deaths in countries as near to the UK as France through anaphylactic shock. Anyone who thinks they have seen an Asian Hornet is asked to report the sighting to the Bee Keepers Association

Natalie Bungay, British Pest Control Association’s Technical Officer said: “A number of BPCA members are acknowledging the perceived increase in wasp activity this year. The Association has seen its wasp referrals rise from 6,565 in 2015 to 7,253 in 2016, between the months of May and August. What’s more, BPCA members are also identifying an increase and extension of the wasp season through the Association’s social media channels.”

Colin Campbell, who is the insect infestation specialist for Pest Professionals, said: “Although not the most loved of our flying insects by a long chalk, for obvious reasons, wasps are fascinating creatures. The nest is built around a single queen and really big nests like this can readily number 6,000 to 10,000 individuals. This one would certainly have been on the higher side of those numbers.

“They grow through a complex symbiosis between the worker wasps, which bring food to the grubs produced by the queen, and the grubs themselves, which secrete a sugary substance on which the workers feed. One is dependent on the other. 

“It’s when the queen stops producing the grubs, usually in the late summer, the workers become a real pest. With no sugar being produced by the nest, the workers go out in search of their own sugar - ice creams, sugary drinks, beer and the like.

“The workers die as winter sets in and only the queen wasps survive the winter. In fact we all need to be thankful to spiders, which predate around 95 per cent of hibernating queen wasps over the colder months. Without spiders there would be a plague of wasps every year!”
