Yeah, we have both but more of those. I didn't realize they were from the western US.Those are stink bugs for sure but the critters I have infesting my place look almost like those, and they are what most people call stink bugs but they are actually Western Conifer Seed Bugs.
Virtually the same thing. They don't bite and if you handle them the stink they give off is kind of like apples. Weird smell but not offensively stinky.
