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.
