The Asian beetle is commonly confused with the lady bug. The Asian beetle is orange in color with black spots where the Lady bug is red. Asian beetles are a common household pest that comes in masses in late fall and winters over in your home. They like warm weather and gather around structures and appear commonly on the southwest side facing wooded areas.
An exterior treatment on you home is as great preventative from getting them and protecting your structure. If you have an established problem it will require a treatment to eliminate.
