Ladybirds should not be confused with the smaller, British Ladybird. Harlequins are a larger, aggressive non-native species from Asia which do some good stuff like eating plant destroying aphids but then they go and ruin it by attacking our native ladybirds which is why we class them as a pest.
They live in an upstairs sash window and huddle by the dozen in the corner of the ceiling. The Harlequins aren’t daft. It’s no surprise that they’ve made their home on a south-facing window above a radiator.
Harlequins snuggle down for the winter they release pheromones to signal to all their Harlequin mates to join them in the cozy crevices of the sash window. Very soon you are invaded. Harlequins will start to fly around the house, looking for their mates. They rest on the curtains, sofa, even a bare arm this is when you call the experts in. MIDS Pest Control will attend and deal with the issue for you.
