The problem with having a spare room in your house is the guests. 

A Hampshire exterminator from Longwood Services Pest Control took on the biggest job in his 45 year career on Sunday after being called to tackle a colony that wasps had built in a spare bedroom.

John Birkett told ABC News Today that he "dressed up looking like 'Batman and Robin,'" before going into the room. He was shocked at what he found. 

At 3ft wide and 1.5 feet deep, Birkett discovered the biggest nest he had ever seen, built by an estimated 5,000 wasps. They had consumed much of the mattress, bedding and pillows to create their wasp mansion.
