I have a question; if the cue to supersedure is a lack of pheromone, or reducing pheromone in/on either the queen or in the brood pheromone - could the odour of varroa treatments be overpowering, or be greater than the pheromone odours?

In other words, the supersedure cue isn’t being triggered because the treatment odours are too powerful.

Of course there are other things that could be in play but I specially am interested in this question.
