Record rainfall has sent the rodents scurrying for shelter, according to Kieran Sampler.
The pest controller is being called out up to 10 times a week to deal with the disease carrying vermin.
One of his latest was for the radiator rat in Wakefield, West Yorkshire.
Video showed Kieran’s dog tackling the rat after he found it hiding behind the wall mounted heater.
“It was an emergency call-out after reports of a rat running around a client’s living room,” he told, Need To Know.
“I quickly found it hiding behind a radiator after it had bolted from underneath the sofa.
“It took some patience but I managed to prod it out.
“It made a run for it straight into one of our working Lakeland terriers, where it was dispatched within seconds.”
“The property itself was very clean and well kept,” he added.
“It’s not necessarily because of defects in the house.
“It’s just the rain.
“It’s been so wet recently and we’ve had so many rainy days the rats are being driven indoors.
“I’m getting lots of call outs at the moment.
“And many of them are to perfectly lovely houses that are in very good areas and in very good condition.”
Winter was the wettest on record for parts of the UK, according to figures from the Met Office.
The UK as a whole recorded 13% more rainfall than the long-term average.
