Re: Advise on luring a swarm
just use a single deep hive box with top and bottom with whatever frames you are using with some lemongrass oil as bait. You might be surprised and get one. A single deep box is perfect size for swarm trappers. I've never done bee-lining but read alot about it and a few stories. It sounds fun and might be very productive in finding a hive for you, but it might be in someones back yard like you are trying to do.
Live life with gusto, having no regrets, being thankful every day, and cherish each moment as it happens.
