Ladybugs are heat loving insects. When the temperatures drop they gather in large numbers and search out a warm and dry place to hibernate for the winter. The insects are attracted to light coloured surfaces that receive lots of afternoon sunlight. Although there are over 450 species of ladybugs or lady beetles in North America, there is one in particular that likes to spend its winters indoors. The multicoloured Asian lady beetle (Harmonia axyridis) is not native to Canada but it has become the predominant species in the country. When you find a group of ladybugs in your room or in your attic, it’s most likely this type of lady beetle. The easiest way to identify this species is to look for an M-shaped marking just behind its head. The only way to keep them from bunking up with you in the winter is to seal up any cracks or openings around your home.
