Cold weather across the UK is set to bring so called "Super-rats" into homes.
Experts are advising homeowners to take steps to avoid the pests from entering people's homes as temperatures are set to fall.
The term "super-rats" refers to rats that have gained immunity to traditional poison baits used across the UK.
These are rats that have gained this resistance through genetic mutation and hereditary traits.

Gardening expert and founder of GardeningExpress Chris Bonnett said: "The cold snap expected this January will mean that these rodents are fleeing their usual habitats and are in search of a warm home.
"You may find that they are trying to enter your home and, if you're experiencing them in your garden, it means they've viewed it as a suitable place to begin building a nest and keep warm.
""This is likely to happen if you have any debris and garden waste on the ground or sources of food growing such as fruits and vegetables.
"Having rats in the garden is a major inconvenience so we've shared a range of ways people can keep the rats out of their homes all together."

Chris Bonnett shared his top tips for deterring the rodents which includes tidying up any rubbish outside, blocking gaps and holes and using strong scents to keep them away from inside the house.
He said: "Rats love warm nests made from debris, rubbish and garden waste. Make sure you clear up any that's built up over winter to avoid attracting them.
"Rats can enter even the smallest of holes on garden sheds and empty plant pots and set up a new home. Cover any gaps no matter how small to prevent them from getting in.
"Rats are not fond of strong scents such as garlic powder or peppermint oil, so it’s worth sprinkling some of this around vulnerable areas in the garden."
Bonnett added its important to keep an eye on water sources and bird tables outside.
He said: "Rats need a water source if they’re going to set up their new home. A dripping garden tap, water butt or blocked drain are all great sources of water for the rodent and can make your garden the perfect home for them.
"Cover drains and grates and ensure they are all intact. If necessary replace damaged ones and check around the perimeter of your home for any other points of entry.
"Bird tables can attract rats, so keep an eye on them and clean up any spilled seeds in the late afternoon once the birds have finished feeding."
