Newspapers are today reporting an increase in “super rats” which are becoming resistant to poisons. These rat populations are spreading across Britain, populations have been found in Kent, the West Country and now close to Surrey in neighbouring Sussex. These rats look like normal rats but they are able to feed on some toxic pellets used in rodent control.
“The British Pest Control Association’s Richard Moseley told Metro: ‘Normal rats are being killed off by poison, so these resistant species are taking their place – it’s only natural that their numbers are expanding. “
The rats in question are spreading further and quicker than anticipated. They can consume some poisons with no ill effects. It is estimated that there are at least 10 and a half million rats in the UK, they can and do breed very rapidly if left uncontrolled. The gestation period is just 21 days and a female can have up to 14 young at a time. Some breeding pairs can have 800 young in just two years.
Poison-resistant rats have been around for 50 years. Last year, researchers found that 70 per cent of rats they tested in some counties were resistant to poisons routinely used by pest controllers. ” Researcher Dr Dougie Clarke told Metro a naturally-occurring mutation of genes was most likely to blame for the development of what he called ‘super rats’.”
These “super rats” can only be controlled by the use of sophisiticated and stronger poisons. If you do have a problem with rats make sure you use a professional pest controller. Rodenticide poisons must be used in a professional manner to retain their effectiveness.
