Ladybirds and ladybugs are often confused with each other, but they have some key differences in their physical characteristics.
Asian lady beetles are slightly larger than ladybugs, measuring about 7 mm long and 5.5 mm wide. They can be red, orange, or even tan in color.

Ladybugs are generally more careful about where they spend the winter, whereas Asian lady beetles often enter homes in search of warmth. If you notice Asian lady beetles congregating in or around your home in fall or winter, they're probably Asian lady beetles.
Asian lady beetles are attracted to warm, reflective surfaces like windows and the south sides of homes, which can make them difficult to avoid.
