South West rats 100% immune to poison

Rats have genetically evolved to withstand poison

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

Random tests found that rats in some towns were 100% resistant to over-the-counter poisons, including Salisbury, Swindon, Bradford on Avon, Tewkesbury, Gloucester and Melksham.

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

The study showed rats in Trowbridge were just 80% resistant, and in Bristol the figure is just 50%.
