A man who lives in Knowsley said he spotted around a dozen ladybirds while working from home.
He said: "I work from home and I looked up at the window and saw lots of little dark dots all over it. I had a look and there were about a dozen ladybirds just walking all over the window.
"I looked downstairs and they were on the windows there too. I know they're harmless – I've just never seen anything like it. All in there must have been about 40, and there were more on the patio that I could see.
"I've only lived here a couple of months so I thought it might just be something that happens in our area, but the neighbours said they hadn't seen it like this before and I saw on social media that there were loads of people getting them as well.
"It would be interesting to know why there's so many of them out there all of a sudden."
Ladybirds often start to appear more as the temperature starts to cool around September and October.
They start to search for warm spots to hibernate during the winter and this can often lead them to people’s homes.
Ladybirds usually hide in groups which tends to mean that if you see one or two of them in your home there is likely to be more to follow.
The Harlequin species of ladybird has become increasingly common in the UK and it can be a bit more invasive than other species and more likely to appear in homes.
How do you get them out of your house?
Ladybugs can be left alone if they are found in your home as they are unlikely to cause any damage or disturbance.
They often appear on windows or in small cracks around the home.
They are unlikely to cause any harm or do any damage and they will tend to fly away in the spring once the temperature starts to get a bit warmer.
To ensure that they don’t get in you will need to make sure that you don’t have any cracks or holes in your home where they could get in.
If you do start to find them around it is important that you act quickly to get rid of them as their scent can attract more ladybirds to the spot.
