Outdoor applications of Demon WP made once a month October - November can help you get control of the boxelder bugs, though you must understand that it will not drive them off of your property, it will only stop most of them from gaining entry into your home. You should also take the time to inspect the outside of your home and seal up any cracks, crevices or gaps you find so that you are limiting places where the insects can enter your home. Demon WP will also help eliminate roaches from your home but you will need to use it in conjunction with a high quality roach bait gel and an insect growth regulator as roaches like to hide and may not readily come into contact with treated surfaces. It is also great for spiders, centipedes and millipedes.
