Just leave them alone. Yes, they are an invasive species, and will
probably wipe out our native ladybirds in due course. BUT like our
native ladybirds they have a voracious appetite for pests like aphids
and scale insect.,

I didn't realise they ate scale insects!

"It has been introduced into many countries as a biological control
agent against aphid and scale infestations in greenhouses, crops and
gardens. Populations have now established in north America, France,
Germany, Luxembourg, Belgium, Holland, Greece and Egypt. In France,
Belgium and Holland numbers are soaring annually."
