Signs of a Harlequin Ladybird Infestation
Although they’re most visible in cooler months, harlequin ladybirds can begin gathering indoors as early as autumn. If you spot any of the following, it’s time to take action:
Clusters of ladybirds around windows, light fittings or in loft spaces
Reddish or yellow stains on walls, ceilings or soft furnishings
A strong, musty odour when disturbed
Ladybirds flying or crawling indoors, especially in sunny spots
Bites on exposed skin – usually harmless, but uncomfortable
Harlequin ladybirds often enter properties in large numbers, especially older or poorly sealed buildings. They can hibernate in lofts, attics, wall cavities and behind furniture, re-emerging in spring. Although not dangerous, they can be distressing, unsightly, and unhygienic when left unchecked.

Frequently Asked Questions About Harlequin Ladybird Control
Why are harlequin ladybirds a problem?
Unlike native species, harlequin ladybirds gather in large swarms, stain surfaces with a foul-smelling yellow secretion, and sometimes bite humans.
They can also outcompete native ladybirds, affecting biodiversity. While they’re not harmful in small numbers, larger infestations are unhygienic and can become distressing.
Are harlequin ladybirds dangerous to pets or people?
Harlequin ladybirds are not dangerous, but they can bite if handled or disturbed, which can cause minor irritation or allergic reactions in rare cases. They also release a fluid when threatened, which can stain surfaces and fabrics. Although not toxic, it’s best to treat infestations professionally.
Why do they come inside during winter?
As temperatures drop, harlequin ladybirds seek warmth and shelter, often entering homes through roof tiles, vents, windows and small cracks. They tend to cluster in warm, south-facing areas like lofts, attic rooms and window frames. Once inside, they remain dormant until spring, unless disturbed.
Can I vacuum or remove them myself?
You can vacuum small numbers, but this can cause the ladybirds to release their foul-smelling defensive fluid, leading to stains and unpleasant odours. Larger infestations or repeated seasonal issues are best handled with professional treatment to avoid spreading and ensure complete eradication.
Do you provide treatment for businesses and public buildings?
Yes, we regularly treat offices, schools, care homes and historic buildings for seasonal ladybird infestations. Our discreet service ensures minimal disruption, and we can provide regular monitoring or preventative contracts if your premises is affected year after year.
