"Stink bugs "stink" because of two chemicals: trans-2-decenal and trans-2-octenal. Interestingly, those two chemicals are also found in cilantro (Coriander sativum), for which the mystery of why some people hate the taste of cilantro with a passion has been researched; turns out that only if you have a specific variant of olfactory receptors you can actually smell these two chemicals. People who have these receptors perceive both stink bugs and cilantro as soapy and pungent, while all others perceive it as neutral to pleasant. The part of the population who perceives stink bugs / cilantro as unpleasant is dependent on genetic ancestry and ranges from 3-21%"
