This wire mesh push-in queen introduction cage is the gold standard for queen introduction and allows the new queen to start laying eggs before she is released. Queens laying eggs have higher pheromone levels and are more readily welcomed by the receiving colony. The queen is placed alone on an area of comb with nectar and emerging brood, and the introduction cage is pushed into the comb to confine her. New bees emerging from the capped brood area under the cage accept her right away, and she begins to lay eggs in the empty cells. The queen is released 4 days later by removing the cage.
