Today I received the first swarm call of the year and just picked them up. I figured an explanation on the ways that I have collected swarms might be useful and/or informational. Swarms are usually quite docile and easy to work with. I’ve seen swarms form on a second story window, on the ground, and the most common on tree branches (from eye level clear up to 30-40 ft up in the air). The biggest challenge with capturing any swarm is getting the queen in the box and then letting all of the other bees follow the queen.
