What Is the 7-Spotted Lady Beetle?
The 7-spotted lady beetle (Coccinella septempunctata) is one of the most recognizable insects in North Carolina. These small, dome-shaped beetles are typically red or orange with seven distinct black spots on their wing covers. Adults measure about 7–8 mm in length.
Habitat & Behavior
While lady beetles are generally considered beneficial insects because they feed on aphids and other plant pests, they can become a nuisance when they gather in large numbers inside homes during fall and winter. They seek warm shelter as temperatures drop, often congregating on south-facing walls and entering through cracks and crevices.
Prevention & Control
When disturbed, lady beetles can release a yellowish fluid with an unpleasant odor that may stain surfaces. Large indoor aggregations can trigger allergic reactions in some people. To prevent infestations, seal entry points around windows, doors, and utility openings before autumn arrives.
