The Alpine spray I bought for Stink Bugs is effective. I spot spray the pests on our porch and door. It doesn't kill them instantly but in a couple of hours I have dead Stink bugs laying all around. I spray around the perimeter of the door and it seems to keep them away for a couple of days. I started using it in the Spring and have only seen a few that did sneak into the house compared to last year. I don't use the spray in the house. FYI, the Alpine dust that I bought didn't seem to work effectively.
