How to Differentiate Between a Ladybug and Lady Beetle

Learn to Recognize the Difference between Harmful and Harmless
Learn to Recognize the Difference between Harmful and Harmless

Ladybugs may seem too benign to require NJ pest control, but the closely related Asian lady beetle isn’t quite as good-natured. How can you tell them apart? Here’s a look at the physical and behavioral differences between the two.

Appearances Can Be Deceiving

At first glance, a native ladybug looks just like an Asian lady beetle, with similar colors and markings. A closer look reveals a black section between a ladybug’s head and body. On an Asian lady beetle, that same section is white with black markings that form a “M” shape.

When Ladybugs Aren’t “Ladies”

Native ladybugs serve a valuable purpose by preying on aphids, spider mites and other plant-destroying pests. While Asian lady beetles were introduced to North America for the same reason, they began to demonstrate less desirable traits.

• When weather grows cold, Asian lady beetles invade homes via cracks, holes and other unobtrusive entry points.

• While native ladybugs are peaceful, Asian lady beetles will aggressively bite, often causing allergic symptoms such as sneezing and coughing.

• Asian lady beetles excrete an odorous yellow liquid that stains fabric, walls and other surfaces.

• In rare cases, Asian lady beetles have sought shelter inside the mouths of dogs, leading to discomfort and sometimes sores caused by the beetles’ secretions.
