A new breed of 'super rodents' in the UK could be posing a threat to people's heath, experts have claimed.
In the last two decades, nearly all the mice and rats in the UK have become resistant to a common type of poison, reports the Mirror. Some 95 per cent of house mice - and 78 per cent of rats - have developed genes that mean they can withstand poisons known as anticoagulant rodenticides.
These substances typically eradicate mice and rats by preventing their blood from clotting. Scientists who have spent 20 years studying rats and mice found the same gene in creatures all over the country.
