Queen Elizabeth is said to be horrified by the infestation of rats and mice in the Buckingham Palace kitchen, as workers were forced to call in exterminators to try to eradicate the vermin which are becoming increasingly resistant to the common poisons.
The Daily Mail says that workers have seen small brown mice in the corridors around the kitchen, and specialists have been called in to lay down poison, but they have admitted there is not much more which can be done to combat the problem. A source told the paper that seeing the small mice have become a regular occurrence.
"Staff in the lower quarters especially have become quite used to seeing little brown mice tearing along the corridors. There isn't a huge amount that can be done."
The main residence at Buckingham Palace, belonging to the queen, dates back to 1703, and so it's not surprising that there is an established pest colony.
