For years of stinkbug infestation I never knew what one smelled like , even though I would pick them up & toss them outside , until last year . I found one that didn't approve of my grabbing it . I don't remember the exact circumstances , but it was hard to grab a hold of , it really didn't smell that bad , it's just that the smell would not go away after washing it many times over , until I could not stand the smell of it anymore .
