Dispatches from the hive mind

Norroa^TM is a paradigm-shifting varroa mite treatment powered by Vadescana, a new Mode of Action in beekeeping. It contains no synthetic chemicals or harsh acids and works by targeting varroa mite reproduction—without harming honey bees. Norroa^TM offers a clean, effective alternative for modern hive management.

To apply Norroa^TM, place the pouch flat on top of the hive frames or bottom board, leaving space for bees to access it. Slowly remove the sticker on a flat surface to expose the perforations, then gently squeeze the pouch to start the flow. If needed, smoke bees out of the way before placing the pouch. The treatment is complete once the pouch is empty, usually within a few days.

NorroaTM targets a specific protein in varroa mites that ultimately stops their reproduction. Studies have shown no negative effects on colony health or brood production.

You can find NorroaTM at Mann Lake locations. For more details, please check out our "Where to buy" page.

Beekeepers save time and money by minimizing treatments throughout the season.
