The 'Three Time Summer Special' treatment plan is a targeted approach for controlling varroa mites in beehives using oxalic acid vaporization. This method involves three treatments spaced 4-6 days apart during summer months, designed to intercept mites as they emerge with new bee brood. The vaporization process heats oxalic acid crystals to create a gas that disperses through the hive, leaving microscopic crystals lethal to mites but safe for bees when properly administered. This strategic timing increases treatment effectiveness by catching mites during vulnerable life stages while minimizing colony disruption.
Key Points Explained:
-
Treatment Schedule & Purpose
- Three applications spaced 4-6 days apart
- Targets the 6-day reproductive cycle of varroa mites
- Increases probability of exposing phoretic mites (those riding on adult bees)
- Particularly effective when brood is present, as it catches newly emerged mites
-
Vaporization Process
- Uses an oxalic acid vaporizer to heat crystals to 157°C (sublimation point)
- Creates gas that permeates hive without opening it
- Forms microscopic spiky crystals on surfaces as vapor cools
- Typical treatment duration: 2.5-3 minutes per hive
-
Summer Application Advantages
- Warmer temperatures improve vapor distribution
- Aligns with peak mite reproduction periods
- Allows treatment without brood interruption (unlike winter methods)
- Less stressful for bees than repeated hive openings
-
Safety & Preparation
- Requires IPM grid boards to reduce vapor loss in screened-bottom hives
- Protective gear needed to avoid fume inhalation
- Precise crystal measurement critical (typically 1-2g per hive)
- Evening treatments recommended when bees are calmer
-
Comparative Benefits
- Higher efficacy than single treatments (estimated 90-95% mite reduction)
- Less labor-intensive than dribble methods
- No residue in honey when properly timed
- Minimal brood impact compared to formic acid treatments
Have you considered how ambient temperature and hive configuration might affect your vaporization results? The same treatment plan may require adjustments based on local climate conditions and specific hive components like ventilation systems.
