Requeening aggressive hives in Oklahoma may not apply to the norm. Nonetheless, my procedure for requeening hives is to find and kill the queen and immediately insert a marked queen in a screened cage between two frames of emerging brood. Seven days later, each frame of brood is inspected for queen cells which are destroyed; and, the marked queen is manually released into the colony. It is not unusual to find up to a half-dozen or more capped queen cells in each colony being requeened. Oftentimes, bees are obscuring the queen cells; thus, bees are shook from the frames for ease of inspection. Two weeks after releasing the marked queen, the colony is checked for brood and the marked queen. So far, 100% of the manually released marked queens have been accepted by the requeened colonies.
