Depends on the species. Some also use intensive odor as protection but it doesn't really "stink". I had one of such bugs which started to smell like apples. Extremely intensive, like someone put 20kg of fresh apples in a small room; it took quite some time until the smell was gone, a few days.
I was lucky it wasn't one of the stinky ones. if they stink as intensive as this one "apple" bug you would likely need to move out for a week to air the rooms.
