Green drone comb IPM for mites

"Green" drone comb is part of Integrated Pest Management and is a nonchemical way to help lower the number of mites in a hive.

Drone brood removal is based on three aspects of the mite’s biology:

• Mites spend most of their time in capped brood cells.
• Mites can be found 5–12 times as often in cells with drone brood as in those with worker brood.
• Mites using worker brood as a host average 1.3–1.4 offspring, while those using drone brood average 2.2–2.6 offspring. So, by removing capped drone brood from an infected colony, you remove a disproportionately large number of mites without affecting the worker population, and you remove those mites with the highest fecundity (from Drone Brood Removal for the Management of Varroa destructor, Nicholas W. Calderone, Cornell University Master Beekeeper Program)

Instructions come with the comb.
