Attracting black soldier flies with corn

Once the BSF are established the result is a nearly odor-free process, but in the beginning it’s best to have a strong odor so the females can locate the unit. I like using fermented corn because even though it has a strong odor I don’t find it as offensive as most rotting food. It’s not a smell that I necessarily like, but it’s one I can live with during the set up phase and once I’ve got a dense colony I can go back to the normal, mild and pleasant odor of a balanced BSF composter.
