- Warmer winters result in shorter or no more brood breaks in the bee colony - as the mites go specifically to the brood, the Varroa population in the bee colony rises dangerously high.
- Conventional treatments against Varroa mites are increasingly failing because the mite has become resistant to the active substances used.
- The active ingredients used for conventional treatment methods settle in the wax - impurities occur in the honey.
- Beekeepers are not able to use any late bees after treating their colonies with chemicals - the honey harvest is weak.
- Many beekeepers are tired of treating the colonies more than 10 times (if no brood collection is used!).
The mite population in the colony must not exceed a certain threshold. This ensures that a healthy, strong colony is not harmed. An efficient and bee-friendly method to keep a low threshold of the Varroa population is heat treatment, also known as hyperthermia.
The basic principle of hyperthermia is that the bee pupae can tolerate a higher temperature than the Varroa mite and that 80% of the Varroa mites are inside the brood frames.
Therefore, we expose the capped brood cells to a warmer temperature, which is harmless for the bee pupae but deadly for the mite. The heat causes the Varroa mite to form shock proteins, which in turn cause cell damage - the mite dies about 20 hours after the treatment. Humidification during heat treatment ensures that the bee brood does not dry out and become damaged - the bees continue to develop healthily.
We recommend three heat treatments during the year: an initial treatment in spring, a summer treatment and an autumn treatment. With the above three treatments, the mite has no chance to damage the hive and the colonies remain healthy. For more information, please contact us by e-mail or phone.
