I've been fortunate to do quite a few swarm captures, cut-outs and trap outs this Spring. I just did a cut out from the 2nd floor of a home & picked up a smell different from the other jobs I've done. These bees have a burnt smell to them. This scent persists in the remote spot I keep them to insure I don't contaminate other hives. While I'm quite aware of the pleasant scent they give off when they get a new hive body offered when they swarm, this scorched odor is new to me. Can any of you offer an answer on what I'm smelling?
