Harlequins ladybirds are a relatively new type of insect to the UK, with the species first being spotted in 2004. They were introduced to Europe from Asia to control aphids, but are now posing a threat to our native ladybirds, as well as butterflies and other invertebrates. The species can be difficult to identify due to their variable appearance, but differ from the majority of native UK species by their large size (6-8mm) and rounder body shape.Because of their rapid increase in numbers Harlequins ladybirds are becoming a pest problem for property owners. They tend to hibernate in cracks, sheds, around windows and inside houses, and although not dangerous to people they can leave behind stains and foul smells, so it is wise to remove them as soon as possible.Professional pest control services are the best way to get rid of the insects as they have the expertise and tools to remove them safely and quickly, and prevent them from returning. Harlequins ladybirds may bite when disturbed, and excrete a pungent yellow liquid that will stain surfaces. Experienced pest control specialists can prevent any further damage to your home and protect your family from any harm that may occur in removing the insects yourself.
