Giant rats

Rise of the genetically-mutated SUPER RATS: Giant rodents that are immune to poison are spreading at 'rapid speeds'

  • Humans have been using the same rat poisons since the 1950s
  • But rats have developed a mutation that allows them to survive poisons
  • Out of 17 UK counties tested, every single one of them had resistant rats
  • Reports this year suggest that rats in the UK are also becoming bigger
  • 'Super rats' are expected to outnumber humans two to one by next year
  • Footage of the rats will be shown on the Tonight programme, on ITV at 7.30pm BST
