I got a call from a distraught employee of a local factory saying that she had a swarm of bees in her tree. I went out to find that the swarm had settled nicely in a knot hole in a tree. So I rigged up a nice little bee vac. (Making sure it wasn't so strong it wouldn't hurt the bees.) I sucken as many up as I could and brought them home. (Of course, I never did get the queen, just a pound or so of bees.) I put them into a hive body above an existing hive with news paper in between (hoping to beef up what I have). I didn't provide an exit hole but sprayed the bees down nicely with sugar water before closing them up. That was last night. I checked tonight and all new bees are dead. So, I'm looking for what I did wrong. Was it leaving them with out an exit? If so would they have stayed in the hive body without a queen? I'm feeling pretty bad about executing such useful creatures.
