Although my screened bottom board design has worked pretty well (it is essentially a standard screened bottom with a beetle-baffle built into the frame), I wanted to redesign with a few new features, so I came up with this idea. There are several other details, but the primary one is 2 vertical entrances, 3/8" x 2-3/4", projecting down from the bottom board. There are sheet metal "snouts" that project down another 3/8", so SHB can't just crawl around the corner.
Does anybody here have any experience with such a concept? I haven't been able to find anything that talks about such a feature.
