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.
