Fascinating!
Jen: "Should I let the queen dry off for awhile before adding her to the trap tomorrow?"
Iddee: "No. Give it a few more days, then just add a few drops of alcohol to the landing board about weekly. Keep adding queens to the lure as you have them. The alcohol evaporates and leaves the pheromone smell."
So I'm reading this as put the queen in the alcohol, which lets the pheromone perfume up the alcohol. Which i'm assuming can be rubbing alcohol or vodka. Then after a few days put a few drops onto the landing board.
In my case, my queen was only in the alcohol overnight. So that's not very potent pheromone alcohol. I took my queen out of the alcohol and placed her directly in the swarm trap. When and if I catch a swarm, I'll retrieve her from the bees and put her back in the alcohol.
