Some of those virgins like to fly away if given a chance.....I hope yours did not do that. Good luck with those queens. :-)
Lauri Miller, on another bulletin board, says she sometimes puts virgin queens or (ripe queen cells) in a queen-right hive and lets the virgin kill the old queen, then mate. It would save tearing the hive apart to find the old queen. A (just hatched) virgin queen will not begin to produce any pheromones for 12-24 hours, and the bees ignore her. Has anyone here tried this method of requeening?
