Have the rats in your town become too powerful for poison?

A new body of evidence uncovered by the University of Huddersfield has proven that rats across large swathes of Britain have now become genetically evolved to withstand common household poison.

The findings will be shown on the Tonight programme on ITV at 7:30pm this evening, and later on the ITV Player

Random tests found that rats in some towns were 100% resistant to over-the-counter poisons.

The university spent seven years collating the information, using rats tails gathered by pest controllers.

The towns in the study were selected randomly to build up a picture across England, Wales and Scotland.

Here is a list of UK towns where rats are most resistant to poisons:

  • Reading, Berkshire - 100%
  • Kelton, Dumfries and Galloway - 100%
  • Glencaple, Dumfries and Galloway - 100%
