I had to google this critter.
You guys up there have all sorts of critters!
Box Elder Bugs cause concern in the autumn when they gather in considerable numbers on the warm outside walls of homes and sometimes find their way into houses looking for a suitable place to over winter.
When they gain entry to buildings through cracks or other openings they remain in wall cavities and will occasionally emerge inside the home in the spring. They will not breed indoors, so there is no danger of starting an “infestation”.
They cause no structural damage whatsoever but they can “spot” interior furnishings with their droppings. They can't bite, they don't eat anything on the inside of your house, including house plants, and they won't harm you, your family or your pets.
Looks like a ball peen hammer's in order here.
