Answer: Boxelder bugs are harmless, and the population may have soared just because of a lack of predators and the right conditions. The same thing happened at my house with lady bugs! Chances are that either this year or next the populations will fall back to tolerable levels naturally. Unfortunately, there is not much you can do to prevent the explosions except perhaps go to great lengths to encourage predators such as birds. If you really get to a point where you feel you must control the bugs indoors, there is a product called Drione, a silica aerogel (antidessicant) which also contains the insecticide pyrethrum, that is moderately effective. Use with caution because it is toxic to fish, and be sure to follow all the directions on the label. You might also contact your cooperative extension office (313-971-0079) to inquire about the high populations. Good luck!
