Information on Ladybirds

Ladybirds are probably the last insect to cross your mind when you think of pests, however to anyone who has had a problem with ladybirds, it could be a nightmare!

The Harlequin ladybird is a non-native invader that is believed to have landed on the shores of the UK in 2004, originating from Asia. They have since spread rapidly across the whole of the UK. So what is so harmful about the Harlequin ladybird?

Most non-native invasive species have a detremental effect of the UK wildlife, often changing ecosystems in a very short space of time and out competing their rivals. The Harlequin ladybird is a cannibalistic species and it is directly related to the decline of at least seven native ladybird species. As a result, this has a knock on effect to native wild song bird populations, that rely on ladybirds for food. Overall, all non-native species in the UK are estimated to cost the economy £1.7 billion each year!

Harlequin ladybirds can be tricky to identify, they are quite large, usually 6 – 8mm in length. They have red-brown legs and a dome shaped back. Their colouration varies vastly but many are orange with around 16 black black spots and a prominent white ‘false eye’ marking at the front of its back.

Due to the natural breeding behaviours of ladybirds, Harlequins can completely take over a room in both domestic and commercial premises. An adult Harlequin can live for 2 – 3 years and a female can lay up to 1000 eggs, which will typically hatch within 3 – 5 days. Commonly, the Harlequin ladybird will lay her eggs on window sills both internally and externally, inside cavity walls, cracks and crevices and loft spaces. Luckily their peak season is relatively short, with the height of this being in autumn.

The Harlequin ladybird can secrete a foul smelling liquid, as a defence mechanism, this stain fabrics and soft furnishings. They will rarely bite and they are not poisonous, however we do recommend you express caution if you come across Harlequin ladybirds. We also strongly recommend that you do not use over the counter products to attempt to remove them, this can be expensive, unlikely to work effectively and it could even make the problem worse. Seek professional advice before attempting to remove these.food items are stored away in containers with a lid and any spilt food is cleared away regularly, ensuring that you pay close attention to hard to reach areas such as under cookers and white goods appliances. Pet food is also likely to attract ants, so clearing away any leftover food after feeding time is advised.
