According to experts, many of the insects turning up in homes are harlequin ladybirds, an invasive species that has become widespread across Britain since arriving in 2004.

that → accord → 2004
They are noticeably bigger than native ladybirds and may bite if handled, leaving a red mark.

They → bite → mark
As the weather cools, the insects begin searching for sheltered spots where they can spend the winter in a dormant state.
asserted
they → cool → state
That often brings them into close contact with people, as houses provide the warmth and protection they are seeking.
asserted
they → bring → warmth
John Whiteley-Wilkson, managing director of Acorn Environment Services, said: 'People are often surprised by how many ladybirds appear all at once, but they're simply looking for a safe, dry place to spend the winter.

they → manage → winter
'Homes provide ideal shelter as the weather starts to cool.'
Horrified Brits have shared videos of ladybirds clinging to doorframes and windows.

One reason the influx can appear so dramatic is that ladybirds rarely hibernate alone.
asserted
ladybirds → see → insects
Instead, they often gather together in large groups, meaning dozens can suddenly appear on the same wall, window frame or doorway.
asserted
dozens → gather → wall
'It's completely normal for ladybirds to gather together before hibernation,' Mr Whiteley-Wilkson said.
asserted
Wilkson → gather → hibernation
'While it can look like an infestation, it's usually just a seasonal behaviour rather than a sign of a pest problem.'
Many homeowners first notice the insects on south-facing walls, which absorb more heat from the sun during the day.
The extra warmth helps the ladybirds conserve energy before winter fully takes hold.

You'll often notice ladybirds gathering on the warmest side of a property,' the expert explained.

'They're making the most of any remaining warmth before temperatures drop further.'

'Harlequin ladybirds are pretty distinctive, even though they have lots of colour forms,' Max Barclay, senior curator of beetles, said.

Barclay → have → beetles
'You can find different varieties, from red with black spots, to orange ones and even black ones with red spots.

Unlike native species, which typically have black undersides and legs, most harlequins are orange underneath with orange legs.

Harlequins are also known for carrying a sexually transmitted disease, called laboulbenia, which is a fungal infection that forms scales on the wings of ladybirds.
asserted
that → know → ladybirds
Thankfully, it cannot infect humans.

it → infect → humans
'It's a fungus that grows on the exoskeleton and we don't have one of those,' Mr Barclay said.

The easiest way for ladybirds to get into your home is through small gaps along the edges of loose-fitting windows.
asserted
ladybirds → get → windows
And while it's common to find them in your home, experts urge people not to kill them.

experts → find → them
'These ladybirds don't want to be in your home any more than you want them there,' Mr Barclay said.
asserted
Barclay → want → them
'If people squash them, they can stain walls with their defensive yellow chemical secretions which can be slightly smelly.
asserted
which → squash → secretions
'
To get rid of the insects, the best thing you can do is to 'help them find a way out', Mr Barclay explained, adding: 'The ladybirds will be grateful and may even repay the favour by eating some of the greenflies on your roses.'
For those keen to keep the insects outdoors, experts recommend sealing small gaps around doors, windows and air vents.

experts → rid → doors
Ladybirds aren't trying to invade your home – they're simply looking for somewhere protected to spend the winter,' Mr Whiteley-Wilkson concluded.
asserted
Wilkson → try → winter
'Preventing them from getting inside is usually just a case of sealing the small gaps they use to enter.'
