In the battle against the Varroa destructor mite beekeepers needs a few tricks to help combat theses nasty parasites.
One tool is Drone Brood Management, this is an organic practice of culling drones from this specially built frame every 24 days or when you notice the frame has been capped.
The female Varroa Mites prefer Drone brood due to the increased gestation period; Drone brood is 8-10 times more attractive to a female mite. So culling the drones on this frame is part of a program to naturally reduce mites in your hive.
We recommend you have one frame per brood box. This package contains two Drone Management Frames. The tops of the frames are coloured green to make them easier to spot in your hive. The colouring is a food grade colouring.
These frames are full-sized Langstroth frames with a plastic frame in the top section. You use your hive tool to remove the capped drones below the top section on inspection. The bees normally use the top part of the frame to store food for the brood.
The Frames comes with full instructions.
