I have a couple of hives I think are getting ready to swarm (based on numerous queen cells in both). They are in my backyard. What are my chances of getting them to land on a low branch of some of my trees or bushes if I daubed a little lemongrass oil on a low branch or two? I know it probably couldn't hurt but does anyone think it might help me lure them to stay in my yard the first day--and at a fairly low level -- to give me a chance to capture the swarm(s).
