I haven't done it myself but was told about it and shown a cine film by a  
chap who died some years ago. He did it for many years. He used a nuc box  
through which the bees had to pass and kept it stocked with brood. The theory as  
explained to me was that with no income, especially water, the queen would  
rapidly go off lay. The pheromenes of the brood in the nuc might be an  
attractant.

I have  never had a queen to come out of the wall that I have known about.
Have you  been doing this type of removal very long?

When would the queen  exit?
