Lady Asian Beetles & Boxelder Bugs in Waynesville & St. Robert, MO: Fall Invaders You Shouldn’t Ignore

Lady Asian Beetles & Boxelder Bugs in Waynesville & St. Robert

Why Fall Invaders Are a Problem
Fall invaders like lady Asian beetles (often mistaken for ladybugs) and boxelder bugs become highly active in autumn. As nights get cooler, they gather around sunny walls, windows, and siding — searching for cracks to get inside.

Identification Tips
Lady Asian Beetles
These small, orange-to-red beetles often have multiple black spots. They cluster in large groups and release a yellowish fluid with a strong odor when disturbed.

Boxelder Bugs
Black bugs with red markings along their wings, usually found on boxelder, maple, or ash trees. They can gather by the hundreds on the sunny sides of homes.

Risks & Concerns
While they don’t spread disease, both pests can stain walls, give off odors, and create frustrating indoor swarms. Lady Asian beetles can even cause allergic reactions in some people.

How to Prevent Infestations

• Seal cracks around windows, siding, and doors

• Replace worn weatherstripping

• Vacuum pests indoors (don’t crush them)

• Consider professional perimeter treatments before fall peak
