sounds like something wasn't quite right with your set up there. I have found the smell depends a lot on what you give them as greens; e.g. cauliflower is really pongy, and so is mint, but in different directions on the olfactory scale! It's also important to remove anything mouldy as soon as you notice it.I tried it last year but it stinks for me to continue. Part of my problem was I did it in the winter season. So it seem like it took half a year to even get 1/2 inch mealworms.
