FAMILIES in Cornwall are being warned to brace themselves for an invasion of rats over Christmas.
Forecasters predict temperatures will plummet in the next few weeks as Britain is hit by a cold snap.
And pest experts fear that a combination of icy conditions and over-flowing dustbins could lead to a huge spike in the number of rodent infestations over the holiday period.
Rob Simpson, managing director of pest controllers register Basis Prompt, said the double attraction of food and warmth has the potential to lead to big problems.
He said: "There are likely to be many more rats than usual at the moment thanks to the abnormally mild conditions throughout the UK this year.
"But cold weather on the way will drive them into buildings in search of shelter and they'll also go scrounging for food from bins and bird tables.
"So the Christmas and New Year period is likely to provide them with the perfect opportunity, particularly as it's party time with fewer bin collections."
A typical home may have more than a dozen potential entry points for rats, which can transmit a variety of diseases to humans.
They get through gaps as small as 2cm, often using plumbing pipes and unscreened vents or gaps in the eaves and roof edges.
Mr Simpson added: "The first evidence of rats in a home is often noises in the loft as that's where most will head to once they're inside.
"That noise is not something to be ignored as, quite apart from the health risks, they'll foul water tanks and chew on wood or electrical wires which can cause a lot of damage and poses a fire hazard.
"They'll also do their best to find sources of food, which means they can soon move to other areas of the house too.
"Rats also breed rapidly and will create nests in attics or walls, so it's vital to act as soon as any evidence is found."
Advice to prevent infestation:
Seal up any external gaps, holes or crevices that can provide rats with a way in.
Keep bins tidy
Dispose of all rubbish carefully and never leave left-over food lying about.
Areas around bird feeders should be kept clean
Don't leave pet food bowls out overnight
Keep weeds and debris well away from buildings as they can be a handy hiding place for rodents.
Homeowners who suspect an infestation should seek guidance from experts, according to Mr Simpson, who advises people to use pest controllers who are members of the Basis Prompt register.
"That way, they're assured a safe, effective and legal treatment," he said.
"Members must be experts in the field and will always be aware of the latest techniques, products and legislation."
