Biting foreign ladybirds riddled with STDs are swarming towards the UK in their millions this winter.
The black-winged Harlequin ladybirds are invading from Asia and North America and could infect 47 native species while ruining the Christmas party season by spoiling fine wine and secreting disgusting stinky liquids, according to the Daily Mail.
Scientists say they pose a significant threat to their red-winged rivals, carrying the Laboulbeniales fungal disease, which is passed on through mating.
And the invaders are hungry too and eat bugs from their own species such as the British Isles native two-spot ladybird.
Although they are not thought to be as harmful to humans, they can let off a nasty smell and crawl all over the furniture leaving ugly stains.
They also bite when they run out of food, which can spark a severe allergic reaction in rare cases.
The Mail reports that the aggressive interlopers have been flying in aided by the mild autumn winds, and have already been spotted across the UK from Plymouth to Peterborough.
Dozens have photographed the creepy-crawlies in their homes, with Merseyside and Manchester thought to be especially affected.
The UK Ladybird Survey suggests the deadly fungus they are carrying could affect the lifespan or the number of eggs a female can produce over her lifespan, although further research is needed.
They add the Harlequins can "exude a yellow fluid [called reflex blood] which has an unpleasant acrid smell, and which can stain soft furnishings.
"When hungry, harlequin ladybirds will bite humans in their search for something edible. Ladybirds in houses, woken from dormancy by central heating, may bite people as there is no food available.
"The bites usually produce a small bump and sting slightly. There are a few documented cases of people having a severe allergic reaction to harlequin ladybirds."
