Rat expert Professor Steve Belmain told tabloid newspaper The Sun "the heat is increasing the rodent's activity" with the front page warning a "plague" of rats is heading to the UK.
"They can reproduce once a month — and transmit over 60 diseases," Prof. Belmain said.
The Daily Mirror says the heatwave has sparked an "invasion of rats in parks and on beaches."
