I checked on one of my swarm traps this AM, and noticed a few bees checking it out. I have been sitting here for 45 min and the intensity has really picked up. Now I'm wondering if I already have a swarm or if these are just scout bees. There are 10 to 20 beesflying in and around the trap. Will it become obvious, and if so, how long should I give them before I take them home?
