As a biological control

The multicolored Asian lady beetle, Harmonia axyridis, is a species that was purposefully introduced into North America and has now become widely distributed. It is a fairly large species with highly variable markings and is a voracious predator of aphids, particularly on shade trees. However, it has the somewhat unfortunate habit of often wintering in homes, where it may be a nuisance problem. They go into dormancy (diapause) when day length becomes less than 16 hours.
