If you’ve had HOSP attacks, would set up that Van Ert in other box & stick around to see if you can trap HOSP. I’ve heard from people here that fishing line version can work, but the sparrow spooker as we know it has 3 rows of Mylar hanging down to touch top of box on both sides (6 Mylar strips total). Sialis site shows pics.
Hope it all works out!
