However, the statement that bees can “smell fear” has been used in many cases and when taken literally is kind of silly. Bees can identify the scent of fear from humans. The article The Chemical Compositions of Insect Venoms says it so well I will just quote them, “Sadly, this is something of an over-simplification. If things go well this apprehension disappears, immediately or over time as their experience increases. Fear is an internal response that can't be smelled. It would then be tested in parallel with one or several irrelevant, neutral or related (but different) compounds. i think they can because if you go near there nest they think you are going to hurt them.
