Re: Alarm pheromone, smells like....
I know this is a really old thread but I was searching on the smell of alarm pheromone. Last week I was splitting a hive and taking too long (looking for queen) and as I was putting the original hive back together with new frames to replace those I'd removed, I suddenly smelled this very strong scent and the bees began to roar. To me, not like bananas. More like venom, like Tim describes it. Sort of a medicine smell, hard to describe.
Today I went out to check on queen releases, and in a different hive I'd split due to being hot, as soon as I lifted the lid the scent was released again. The queen was out; I can only hope they didn't kill her. I didn't look for her, only removed cage.
Now I will notice it right away. Quite a distinct odor.
