Norroa™ targets a specific protein in varroa mites that ultimately stops their reproduction. Multiple years of field trials have demonstrated up to 18 weeks of mite control with one treatment and no negative impact on colony health or brood production.

Norroa™ is powered by vadescana, a new Mode of Action (MoA) for beekeeping based on RNAi. To use, carefully remove the sticker from the top of the pouch and place it on top of frames or the bottom board, leaving a 1/2-inch space for bees to access the pouch.

** can be applied at any temperature the hive can be safely opened

** targets a specific mite protein, which stops the production of mite offspring.
