As temperatures drop to below freezing, people are being warned to watch out for rats in garages, basements and attics.
Merseyside has been hit by an arctic blast this week as temperatures plummet and a yellow warning for ice has been issued. Forecasters say it is becoming increasingly cold, with temperatures dropping to a minimum of -8C in the evening.
It's not clear how long this cold spell will last, however, it is expected to stay cold into next week with temperatures remaining well below average for the time of year. Following a mild October, Rentokil Pest Control predicts that rat activity is likely to increase in the coming weeks particularly as temperatures fall.
