The Asian ladybird, first observed in 2006 in Poznań, western Poland, has already reached Warsaw. This species, which threatens its Polish counterpart, also feeds on aphids. Its clusters can consist of thousands of specimens.

Methods for combatting this invasive species including sealing doors and windows, as well as the installation of mosquito nets, whilst selected fragrances – citrus, menthol and camphor, can prove useful.
