Chris: What’s that on the ceiling?
Me: A brown marmorated stinkbug.
Chris: We should deal with it *goes to cabinet, grabs hand full of rubber bands*

In short succession, six people with baccalaureate degrees in some sort of science were shooting rubber bands at the ceiling.  After about 5 minutes of firing, I cheated and knocked it off the ceiling with a metal rod and discovered it was not a live stinkbug, but a dried dead husk of one.  I guess that it explains why it didn’t try to dodge.
