Multicolored Asian lady beetle (Harmonia axyridis)
Pest description and damage Rounded with high arching back, usually orange with black spots. In the fall, they may invade houses in large numbers. Biting is occasionally reported, but these bites carry no health effects.
Inspect outside of house for entry points. Seal cracks and crevices with caulk. Ensure tight seals on windows and doors. Concentrate efforts on south and west sides of structures. Repellent pesticides can be used on the outside of structures, but timing is critical to effectiveness. Use of insecticides indoors is not recommended. Beetles found indoors should be vacuumed. Avoid smashing beetles, as body fluids can stain fabrics.
