Another follow-up... the "invasion" is well under way now. Not only at home, but we were at a campground, some 80 miles from home this week-end, and the stink bugs were crawling on the caper there too. Meanwhile, we found a couple live ones inside, which very carefully were placed outside.
This morning at home, when we got up (we sleep in the camper every night), I found 4 dead stink bugs on the floor. I was glad to see them dead and not crawling around. This tells me that the bug bombs I used earlier this year left enough residual killer on the walls and ceilings and cracks and crevices, then when these bugs pass over those areas, they are getting poisoned and die! I'd rather sweep them up off the floor than attempt to pick them up alive!
Anyway ... the "war" is raging, if anyone is passing through Indiana in the next few days (weeks) be sure to pack the bug spray!
