Paul, I agree if you are going any distance. Mine were in for about five minutes and were fine at the apiary. Before I put them in the trunk I popped open the bag and twisted it shut inflated , so they had plenty of air. I did it again when I took them out of the trunk becasue I was worried about them suffocating, but they were fine. The main use is in getting the swarm from where they are located- in a hard place, to the box without having to position the box. It would work equally well on branches. I would not want to go long distances with either a plastic or cloth bag. The box is better.
