Reverse WILL work IF you first correct the source of stress that caused pollen production to begin with. If the source of stress is ongoing, or if you have a true hermie (you don't) then reverse will not work. If the stress is removed and you spray them once, and again 10 days later (or spray preventatively at the first sign of sex) you can effectively forget about the problem.
If your plants are producing bananas due to long/late flowering, reverse will correct them for about 10 days which is normally enough time to harvest, if not, hit em again and youll have another 10 days. Reverse will cause any male sex organs to shrink and fall off, and stop any seed production.
As for the people calling you lazy, they have not given the situation proper thought. You would be acting silly if you had access to a great innovation like reverse spray and yet still choose to just pick off bananas every night.
