Harlequin Ladybirds

Posted by Dawn Bevan at Mar 13, 2010 10:48 AM
We have been invaded by these creatures. They are getting in through gaps in the window frames and attack when you are in the bath! Can they be got rid of? Dawn, Staffordshire

We have had a few of the Harlequins living in our bathroom over the winter, but now the weather is warming up, we have around ten living in the bathroom, and have just started to see them around the kitchen window sill.Is there anything we can do to get rid of them and deter them humanly?

Harlequin ladybirds favour inside buildings as a place for spending the adverse winter months. This is why so many are seen in buildings during Autumn and Spring. They are less conspicuous in mid winter because they are dormant - although the Ladybird Survey receives many messages in Autumn, Winter and Spring reporting large numbers of harlequin ladybirds particularly in window frames. However, Spring is a time in which all ladybirds begin to look for food and a mate. The harlequin is no exception and, so just as quickly as they appeared in houses in Autumn, they will begin to disappear from houses in Spring. Many people ask whether there is an effective way in which harlequin ladybirds can be controlled. The answer is no. It is not desirable to take any direct action, partly because it would make little difference to the harlequin population anyway but more importantly because harlequin ladybirds could be easily confused with other ladybird species which we wish to conserve. The Ladybird Survey and collaborators are exploring the interactions betweeen harlequin ladybirds and other species, to help understand the extent of negative (and positive) impacts of the harlequin ladybird on other species.
