Re: Queens in alcohol
I had never heard of this before and I was super confused!
The pheromone in question is called nasonov and some people erroneously refer to it as the 'queen pheremone' but that is not correct. The swarm attracting pheromone is only produced by workers in their nasonov glands and it is specifically used to orient bees to a hive entrance. Unfortunately it has nothing to do with the queen, she does not have a nasonov gland. Nasonov is air transmittable and air detectable which is how it can attract flying bees. It is also easy to make with essential oils like lemongrass, geranium, and lemon oils.
The queen does have a specific pheromone that she uses to announce her presence inside the hive, but it is oily and spread by touch, not by smell. I would not expect this queen extract to work at all, it literally makes no sense, thankfully it was just $2!
