I use 7 frames swarm boxes made out of waste 9mm plywood and use 1 old frame and rest is foundation. My lure is made of pure alcohol in which I put dead queens in. I have added 2-3 drops of lemongrass oil. Works a treat, I had 2 prime swarm last year. I will use them to make as many split as possible this year.
