Norroa™: Proven, Long-Lasting Varroa Control

Developed and refined over more than a decade, Norroa™ offers beekeepers a powerful new solution for managing varroa mites. Extensive field trials show that a single treatment delivers up to 18 weeks of effective mite control—without harming bees.

Powered by vadescana, a breakthrough Mode of Action (MoA) in beekeeping, Norroa™ specifically targets a protein in varroa mites, halting reproduction and reducing mite populations. Trials confirm no negative impact on colony health, brood production, larvae, adult bees, or queens, ensuring hives remain healthy and productive.

Safe and Sustainable

• Contains no harsh acids

• Designed to protect non-target organisms

• Supports Integrated Pest Management for sustainable beekeeping

Simple Application

• Quick, pouch-based treatment—no measuring or mixing

• Place directly on frames or the bottom board with a ½-inch space for bee access

• Works at any safe hive-opening temperature

With its extended control period, Norroa™ reduces the need for frequent interventions, saving beekeepers both time and money while promoting stronger, healthier colonies.

Application

• Use two pouches per brood box. For hives with two deep brood boxes, apply four pouches total.

• A 2‑dose pack treats one brood box.

• A 12‑dose pack treats six brood boxes (either six single deeps or three double‑deep hive setups).

• Pro tip: For hives with two brood boxes, place Norroa™ between the boxes using a feeder shim.

Key Benefits

• Long‑Lasting Protection – Up to 18 weeks of control, maintaining fewer than three mites per 100 bees in commercial field trials.

• Resistance Management – Introduces a novel Mode of Action (MoA), helping extend the effectiveness of existing active ingredients.

• Proven Effectiveness – Lab studies show foundress mites exposed to Norroa™ produced no offspring.

• Flexible Use – Works across a wide temperature range, as long as conditions are safe to open the hive.

• Boosts Winter Survival – Field trials demonstrated up to 75% winter survival, nearly double the rate of leading chemical treatments.

• Bee Health First – Targets mites specifically, with no negative impact observed on larvae, adult bees, or queens.

• Easy Application – No measuring or mixing required. Simply peel back the sticker and place the pouch on frames or the bottom board, leaving a ½‑inch space for bee access.
