In whatever place of residence i'm at (house or college dorm) i tend to kill on sight, mostly because you never know where they'll go or what they'll get into, and their death brings peace of mind.
If they've made a nest outside my home or whatever, i would let them be, which is also what my parents do.
The only insects i don't smash are stinkbugs, and that's only because of the horrible smell they make. Those i either release or flush down the toilet
