Applying oxalic acid to a beehive involves targeting the bees within the colony, typically when they are clustered and brood is minimal or absent.
Based on the provided reference, a key aspect of the application is identifying the location within the hive where the bees are concentrated. As seen in the video snippet (4:01-5:43), the application is directed towards the bees clustered between the frames. Specifically, the reference notes applying it to the bees from "roughly. The second frame in from the outside over to the second frame and the other side." This highlights the importance of treating the bees directly where they are located on the combs.
The exact method for applying oxalic acid can vary (e.g., dribble, vaporization), but the principle often involves direct contact with the bees carrying the Varroa mites. The reference focuses on where to apply the treatment within the hive to maximize contact with the bee population.
Targeting the Bees
- Identify frames densely populated with bees.
- According to the reference, the application area encompasses the bees from the second frame in from one side to the second frame from the other side. This central cluster is where the majority of the colony resides, especially during cooler periods or in broodless conditions.
- Ensure the treatment makes contact with the bees clinging to the frames and moving within the hive body.
Why Location Matters
Applying oxalic acid directly to the bees is crucial because the treatment primarily targets phoretic mites (mites on the adult bees). It has limited effectiveness on mites inside capped brood cells. Therefore, applying it when brood is minimal (like late fall or winter) is often recommended for best results. The reference's focus on applying to the clustered bees between specific frames aligns with this need to treat the adult bee population.
While the reference details where to apply the treatment within the hive structure to reach the bee cluster, it does not specify the method (e.g., using a syringe for dribbling a liquid solution, or a vaporizing tool). Regardless of the method used, the reference underscores the need to apply the treatment directly onto the bees concentrated in the hive.
Important Considerations:
- Always follow specific product label instructions for mixing, dosage, and application method (dribble, vaporization, etc.).
- Personal protective equipment (PPE) is essential when handling oxalic acid.
- Application is often most effective when the colony is broodless.
Understanding where the bees are located within the hive, as shown in the reference, is a fundamental step in ensuring effective application of oxalic acid treatments.
