Giant rat two feet long found in Grimsby in England

A giant rat over two feet long has been captured by a pest controller in Grimsby, Lincolnshire, England. Rats are not only getting dramatically larger, they are also becoming more resistant to over-the-counter rat-poisons, say experts.

Jeff Sullivan, 58, who owns the firm SWAT Total Pest Control, found the animal at a client’s home. He said it was the biggest one he had ever come across in his eighteen years in the business.

The real thing – no trick photography

Some claims have appeared on the internet of people catching four-foot long rats. However, they were later found to be much smaller – the animals had been held at arms-length close to the camera – thus creating the illusion that they were much bigger than they really were.

Mr. Sullivan said:

“There is a lot of misrepresentation with guys taking photos of rats with mobile phones and holding it out at an extreme arms-length to create the illusion that it’s bigger than it really is. But this is the real deal, it’s the largest rat I’ve ever seen.”

Rats’ diets are changing. They are eating high-protein food and ‘bulking up’, Mr. Sullivan warned. He added that they are becoming much more difficult to kill, because of progressive poison resistance.

Mr. Sullivan added:

“I’m just glad I never had my jack Russell on this one, I think the rat might’ve won.”

Rats spread diseases

Rat infestations are a serious public health problem. The most common species – the black rat (Rattus rattus) and brown rat (Rattus norvegicus) – carry more than thirty-five dangerous diseases, including rat bite fever and leptospirosis.

According to the Centers for Disease Control and Prevention in the USA:

“Without treatment, Leptospirosis can lead to kidney damage, meningitis (inflammation of the membrane around the brain and spinal cord), liver failure, respiratory distress, and even death.”

As over-the-counter poisons are becoming less effective in dealing with rats, the only way today to solve the problem effectively is to call a fully-qualified pest controller.
