Getting warm and cosy is often quite appealing for us humans and it's the same for rats who look for warm places to nest.
Since some of the places they choose may sometimes be in our homes and gardens, it’s worth knowing what harm they can actually do to humans and pets.
The rodents are known for carrying diseases but how harmful are they?
What diseases are carried by rats?
Brown rats carry diseases such as “leptospirosis or Weil's disease, salmonella, listeria, toxoplasma gondii and hantavirus”, according to the British Pest Control Association (BPCA) website.
These diseases can be passed on to humans, usually by rat urine.
The NHS website says you can get leptospirosis “if soil or freshwater (such as water from a river, canal or lake) that contains infected pee gets in your mouth, eyes or a cut, usually during activities like kayaking, outdoor swimming or fishing” or “you touch an infected animal's blood or flesh, usually from working with animals or animal parts”.
It adds that getting leptospirosis from pets, other people or bites is “very rare”.
Can rats be harmful to dogs?
The PDSA website explains that dogs can also get leptospirosis which is a disease that is caused by bacteria.
It is serious and often fatal for dogs. It can be caught from a number of things including from the urine of rodents – a dog who spends lots of time on a farm may come across this.
How to get rid of these common garden pests
Dogs can also catch it from infected dogs or if they sniff or lick the floor where an infected dog has urinated.

Lepto can live in wet ground and freshwater, including rivers and lakes, for months.
Vets can vaccinate dogs against the types of leptospirosis found in the UK.
Symptoms of leptospirosis in dogs include a high temperature, jaundice (yellow gums and eyes), muscle pain and limping plus vomiting and more.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
