The multicolored Asian lady beetle (Harmonia axyridis) is a red to orange “round-top” beetle that is about 1/3” long with black spots and white markings behind the head. Asian beetles have been known to pinch people and stain structures. These beetles usually do not bother us in the summer, but later in the season, when the nights get cooler and especially after the first freeze, we see these beetles head for shelter. These beetles are considered an overwintering pest.
Can Asian lady beetles harm me?
Multicolored Asian lady beetles do not sting and have not been known to cause any human disease. However, Rhinoconjunctivitis and mild skin irritations have been reported with the multicolored Asian lady beetle. They also have been known to give a slight pinch.
Do Asian lady beetles cause damage?
If a home or business experiences a large number of these beetles, there are cases where staining and odor has been known to occur. For the most part the biggest issues is that they are a nuisance pest and are not tolerated by many people indoors.
What can I do?
Multicolored Asian lady beetles are an overwintering pest. In the Fall, sealing gaps in the foundation, fixing door seals or pipe entries will help, but these critters seem to find their way in. As a home owner, you can vacuum the pests up and remove them as they appear. With the Asian lady beetle make sure you use the hose end or shut the beater off on the bottom. The beater on the vacuum will agitate the live beetles and they can release an unpleasant order. In addition, they have been known to stain a variety of surfaces due to “reflex bleeding”. If you are seeing them in the winter, they are in your home or building and you will probably see them throughout the winter months.
