Norroa brings a very different approach to Varroa management. In this installment of the Beekeeping Today Podcast Varroa Treatment Series, Jeff Ott and Becky Masterman welcome Dr. David Peck of Betterbee to explain how this new treatment works and, just as importantly, when it may—or may not—fit into a beekeeper's management plan.
Unlike treatments designed to quickly kill mites, Norroa uses RNA interference, or RNAi, to disrupt reproduction in female Varroa mites. The active ingredient, vadescana, is delivered in sugar syrup pouches that bees consume and incorporate into brood food, where reproductive mites can be exposed.
That means timing matters. Norroa requires actively reared open brood and is intended to hold mite populations down over time rather than rescue a colony already experiencing dangerously high mite and virus pressure.
David also explains pouch placement, treatment timing, monitoring challenges, cost considerations, and why local nectar flows, dearth periods, colony development, and mite pressure all matter when deciding whether Norroa belongs in your Varroa management program.
