The swarm that absconded yesterday from the hive I put them in finally chose the hive again as home. Sometime around 1 pm they landed back in it. This proves the concept to me of using a bait hive to bring down swarms high up in trees. I kind of think of it as fishing.
Also, I presented a lecture on Swarm Traps to my local bee club. I think it went well. I strongly believe every beekeeper should have at least 2 traps deployed during spring.
