I would be really careful about using swarm Commander inside a hive. I have never actually used swim Commander, but I do use lemon grass oil. It’s easy to get too much LGO and then the bees move outside the box and start building comb on the bottom of the swarm trap. I believe that the smell interferes with the pheromone communication going on in a colony. I have also seen a swarm take flight after I put a box with LGO next to it. The point is, swarm commander is for attracting scout bees, not for making a box more attractive.
