I think it's just bananas, honey and brown sugar mixed with gelatin and a mold inhibitor. Nothing special about it, except that it's probably convienant to use. I've noticed that roaches like sweet things- whenever I paint brown sugar moth bait on trees in dry pine- oak woodland, dozens of parcoblatta nymphs are usually the first insects to find it- even though it's several feet above the ground. I tried feeding brown sugar to my dubias and they seem to like it too.
