Harlequin ladybirds are becoming more a problem to householders during the Autumn/Winter months. Like cluster flies they come inside gathering around window frames to hibernate over winter. As a servicing pest control company we have seen an increase in Harlequin Ladybird enquiries, during the Autumn months, over the last 3 years.
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 very informative http://www.harlequin-survey.org/recognition_and_distinction.htm
We can help by carrying out an insecticidal treatment to internal parts of window frames, this will control Harlequin Ladybirds once inside but please note that we cannot stop them from coming in. If you would like to arrange a treatment please let us know how many windows are affected (usually the sunniest side of the house south/south west).Read more
