Stink Bugs seem to be headed South. We started with them in Virginia (Actually I think PA got them before we did) Now we are seeing them in SC. Where we did not before.
Some years are worse than others. Mostly see them in the fall. The first couple of years we had so many we vacuumed them up. Used a shop vac as they will ruin a good vac and their stink will get in and smell for a long time.
Don't recommend stepping on them. They don't seem to bite but their smell if it gets on your hands is fun to get off.
The internet has many suggested home made traps. One we use involves a water bottler taped to a stick with some soap water in the bottle, The bugs are usually not fast and like ceilings place the bottle over the bug and they will fall in . Replace the cap wait for the next sighting..
