Thanks for that link. My Seek app has told me that mine are stink bugs. They fly into our house unknown, and some Falls are worse than others. Last year was pretty bad. I really hate them. If you accidentally suck one up in the vacuum, the whole place smells like them. Yuck. If they would just stay outside, it wouldn’t bother me as much.
They are attracted to light. Do a search for Stink Bug Traps and there are some that people make from pop bottles with christmas candle lights in the bottom.
