☀️🐝 Can a simple limewash keep beehives cooler during summer heat?
In our latest BroodMinder field study, we compared untreated metal hive roofs with traditionally limewashed roofs using real temperature data from BroodMinder sensors.
The result was striking: during hot summer afternoons, limewashed roofs stayed up to 10°C (18°F) cooler than untreated roofs.
In this video, discover:
✅ why hive roof temperature matters;
✅ how to prepare and apply traditional limewash;
✅ how the trial was measured with BroodMinder sensors;
✅ the temperature differences recorded across multiple hives;
✅ how this natural, inexpensive technique may reduce the cooling effort required from honey bee colonies.
A centuries-old Mediterranean practice, tested with modern hive monitoring technology. 🌿📊
