oooo GOD.. I hate HATE these critters!!! They really 'see' well too!!
Tell me.. if you know.. what does that odor they emit smell like? A few times I smelled something like some sort of moth ball.. is it like that at all?
I can't say I've had anyone describe the odor to be like moth balls but most people seem to think stink bugs smell like skunk or something decaying or even dead. Others have said the odor is like similar to cabbage, rutabagas and even some spices like cilantro. Remember, smell is a personal thing and will most certainly vary from person to person. Also, there are a few different species of stink bugs here in the US which could mean different odors. But the one common thread is that most everyone seems to think the smell is bad.
