Scientists are worried about the growth of the population of a new, mutated species of rats throughout the country. At the moment, rodents with a genetic mutation have already been found in central and southern England.
Unwanted guests are called super-rats, because after a number of genetic modifications they developed immunity to common poisons against pests. Scientists are worried that rodents breed incredibly fast and transmit immunity to offspring, because no one is ready for a massive influx of "immortal" disease vectors.
A huge degree of mutation of rodents was revealed at the University of Reading. It was called L120Q and found in rats throughout central and southern England.
Dee Ward-Thompson of the British Pest Control Association said: "The study emphasizes that resistance to poisons is manifested in rats all over the country. Rats without mutation are easily destroyed. The rodents, which are resistant to poisons, multiply and leave a population with immunity. An increase in their number may be dangerous for public health.
The exact causes of the emergence of a new genetic strain are not established, but most likely the mutation is caused by poisons that eventually developed immunity. People should not try to "treat" rats on their own. This will be handled by specialists of the pest control service."
