Harlequin ladybirds can be a nuisance inside properties during the Autumn/Winter months, as the weather starts to cool down. Like cluster flies they come inside, gathering around window frames or clustering in corners, to hibernate over winter.
The Harlequin ladybird (Harmonia axyridis) is not a native species of the UK and is a relatively new visitor. Originally from Asia the Harlequin Ladybird is now being found in North America and Europe. In North America it is also known as Halloween Ladybird as it becomes more a problem inside properties at the end of October.
How to Identify the Harlequin Ladybird? I can do no better but to direct you to the The Harlequin Ladybird Survey website which is informative.
A few Harlequin ladybirds can be removed with a vacuum cleaner by the householder.
For heavy infestations we can help by carrying out an insecticidal treatment to internal parts of window frames, this will help to control Harlequin Ladybirds numbers once inside, but please note that we cannot prevent them from coming in.
If you would like to arrange a treatment please contact us. We will need to know how many windows are affected (usually the sunniest side of the house south/south west).
