What Is the California Lady Beetle?
The California lady beetle (Coccinella californica) is a native ladybug species occasionally found in North Carolina. These small, dome-shaped beetles are typically red-orange with no spots or very faint markings, distinguishing them from the more common spotted lady beetles.
Habitat & Behavior
California lady beetles are beneficial predators that feed primarily on aphids and other soft-bodied plant pests. A single beetle can consume hundreds of aphids in its lifetime, making them valuable allies for gardeners and farmers.
Like other lady beetle species, California lady beetles may enter homes in fall seeking overwintering shelter. They congregate on sunny exterior walls before finding their way inside through gaps around windows, doors, and siding. While they do not damage homes or bite, large aggregations can be a nuisance.
Prevention & Control
If lady beetles enter your home, the best approach is to gently vacuum them up and release them outdoors rather than crushing them, as they can leave staining secretions. Seal cracks around windows and doors before fall to prevent entry. Avoid using pesticides on these beneficial insects whenever possible.
