Norroa by GreenLight Bio

Norroa by GreenLight Bio Norroa delivers science-backed varroa mite control to help beekeepers protect honey bee colonies.

Powered by vadescana and leveraging RNA interference (RNAi), Norroa targets a specific protein in varroa mites to stop their reproduction while keeping bees safe and supporting overall hive health. Field trials have shown long-lasting mite control with one treatment and no negative impact on bee health or brood production. Designed to fit into modern hive management practices, Norroa offers a new mode of action and practical, sustainable mite control for beekeepers.

Summer buildup is in full swing. 🐝☀️

Right now many colonies are
• Raising brood
• Collecting nectar and pollen
• Expanding population
• Supporting summer honey flow

Strong summer buildup creates a lot of activity inside the colony this time of year.

Busy season means every minute counts. Norroa helps simplify varroa management with less labor, fewer hive disturbances, and effective mite control, saving time for beekeepers while reducing stress on colonies.

No measuring.
No mixing.
No complicated setup.

Simply place the pouch inside the hive and activate flow. As nurse bees feed developing brood, the active ingredient is naturally distributed throughout the colony, reaching Varroa mites where they reproduce and helping break the mite life cycle.

🐝 Meet Adam! 🥁

Adam grew up around agriculture in North Dakota, but his first love was music. As an accomplished drummer, he performed across the country playing nearly every genre imaginable while earning undergraduate degrees in Music and Fisheries & Wildlife Biology. He recently completed his Master’s in Biology as well.

Adam began working with bees as an apiary inspector in North Dakota in 2018. At the time, he jokes that he “had 800,000 colonies” because inspecting bees was his full time job, long before he started keeping his own colonies a little over a year ago.

He has always had a passion for conservation and the outdoors. When he’s not working with bees, you’ll probably find him hunting, hiking, fishing, camping, cooking, or still playing drums with his band.

One of Adam’s favorite parts of the beekeeping industry is connecting with beekeepers from across the country and hearing the different challenges and experiences each season brings.

If you see Adam at a conference or convention this year, make sure to stop by and say hello 👋🐝

What separates strong operations from the rest? 🐝

From the field:

“Consistency is everything when you are managing large numbers of hives.”

Mites reproduce continuously as long as brood is present. Maintaining consistent control across brood cycles helps prevent:
• Population spikes
• Late season losses
• Reactive treatment cycles

At scale, consistent control supports:
• Predictable performance
• Easier management
• Stronger outcomes across the yard

How are you maintaining consistency across your yards?

Did you know there are more than 3,600 species of bees in North America? 🐝

This World Biodiversity Day, we’re recognizing the important role pollinators play in healthy ecosystems, agriculture, and our food systems.

Native plants like blackberry provide important forage for bees and other pollinators throughout the season.

At Norroa and our parent company GreenLight Bio, we are focused on developing targeted agricultural solutions that support honey bee health while helping reduce harmful chemical pressure across the landscape, benefiting pollinators and biodiversity as a whole.
