In more than 17 counties of the United Kingdom there is atmosphere of fear. A new breed of genetically mutated ‘super rats’, immune to poison, are spreading into residents’ houses at alarming speeds.
Scientists have now begun charting their rapid invasion into new communities by monitoring their progress in 17 counties in the UK.
Around 30 per cent of rats in Kingston are immune to poison, in Sheffield it is 40 per cent, while 75 per cent of rats in Southampton are immune.
While the rats have been changing, humans have been using the same anticoagulant poisons since the 1950s.
