Multi-coloured lady Beetles / Harmonia axyridis

Multi-coloured lady Beetles / Harmonia axyridis
During the spring and summer, multi-colored Asian lady beetles feed on aphids in gardens, meadows, and trees. But in the fall, they sometimes congregate on the sunny sides of houses and on porches or in garages. As the afternoons cool off, some of these beetles make they way indoors. If squashed the beetles may stain fabric and painted surfaces. Some people have reported receiving a mild "nip" by beetles that have landed on them. There have been concerns that large numbers of beetles may possibly cause air quality problems indoors that could trigger allergies and/or asthmatic reactions.

Residential Recommendation

It is amazing how little tolerance many people have to lady beetles inside the house. Folks love them in the garden but hate them inside. We do not recommend spraying Harmonia lady beetles. It is better to gently sweep them up and return them outdoors. If large numbers of these insects continue to invade a house, it probably means that the weatherstripping around the doors and windows needs repair. One encouraging aspect of multicolored Asian lady beetle biology is that they are victims of various predators and parasites so that a population may be locally abundant, but after a year or two, the numbers of Harmonia lady beetles drops off dramatically.
