Treating the outdoor areas with a product such as Bifen will help to control those that wander near the house, but since this insect is winged and can fly, they can migrate towards your house from far away, that's why control is nearly impossible.
All that you can do is treat outdoors, the lawn, outer perimeter of home, etc, every few days or weeks and hope for control. Other than that, keep a good shop vacuum handy and just suck them up indoors.
Hope this helps.
