I am currently using a swarm box for my cell starter and was considering using a modified swarm box as outlined in Contemporary Queen Rearing by Laidlaw. One question I have is could one use a division board instead of a screen to separate the swarm box from the parent colony? I'm assuming greater success is achieved with the screen because it will allow for the queen pheromone to reach the swarm box. But a swarm box is queenless? Any experience/info. would be appreciated.
