Preparing an oxalic acid mixture for five hives involves precise measurements, proper dissolution, and safety precautions. The mixture consists of oxalic acid, hot water, and sugar, which can be applied via dripping or vaporization (using an oxalic acid vaporizer). Key steps include dissolving 8.75g oxalic acid in 150g hot water, adding 150g sugar, and labeling the container as poisonous. Application requires protective gear, avoiding low temperatures (<40°F), and using a syringe to distribute 50cc per hive (5cc per bee cluster).
Key Points Explained:
-
Ingredients and Measurements
- Oxalic Acid: 8.75 grams (for 5 hives).
- Hot Water: 6 fl oz (~150 grams) to dissolve crystals effectively.
- Sugar: 3/4 cup (~150 grams) to create a syrup for bee uptake.
- Why? Hot water accelerates dissolution, while sugar ensures bees ingest the treatment.
-
Mixing Process
- Dissolve oxalic acid in hot water first, then add sugar to avoid crystallization.
- Stir until fully dissolved to ensure uniform potency.
- Seal and label the container as "POISON" to prevent accidental exposure.
-
Application Methods
- Dripping: Use a syringe to apply 50cc per hive (5cc per bee cluster).
- Vaporization: Sublimate the mixture using an oxalic acid vaporizer for even distribution.
- Safety Note: Avoid hive opening below 40°F to protect bees from cold stress.
-
Safety Precautions
- Wear gloves, goggles, and a mask to prevent skin/eye contact or inhalation.
- Carry water to dilute spills immediately.
- Store labeled containers away from children/pets.
-
Environmental Considerations
- Apply during bee activity (daytime) for optimal uptake.
- Avoid windy days to prevent drift during vaporization.
This method balances efficacy with bee safety, leveraging chemistry and careful handling to combat pests like Varroa mites. Always follow local regulations for pesticide use.
