Does anyone understand how this works? If you pinch a queen and put her in alcohol, this works as a lure to attract swarms. But if instead of pinching her, you put that same queen into an existing hive, the bees would probably kill her.
I had 5 or 7 queens in alcohol and it has no effect on swarms. I throw away that stuff. I Tried it on several swarms.
I had a Russian lure greese which atracted very well swarm.
One swarm dropped it down from 15 m high level.
Then I have used a French spray. No effect. it think that it evaporate in sun shine too quickly. A greese keeps its aroma longer.
