"In my opinion, the simultanous application of the Varroa Controller and the sugar powder complement each other perfectly. As a consequence, one can reach the highest reduction of the Varroa population as possible – without providing loop holes!"

Varroa treatment – a new perspective with hyperthermia
Functioning principle - Heat treatment
- In the closed breeding cell there are two living organisms - the bee larvae and the Varroa mite
- The basic principle used takes advantage of the fact that the bee larvae tolerates higher temperature than the Varroa mite
- With hyperthermia only heat is used to treat against the mite - there are no chemicals involved
The Varroa controller exposes the varroa mites and the bee larvae to a specific temperature which kills the mite without harming the bee larvae.
When reaching the specific treatment temperature, the vital protein synthesis process of the Varroa mite is damaged. For the bee larvae, this temperature level is not harmful. The development of the Varroa Controller is based on the known method of hyperthermia (already investigated in the late 1980s).
A successful series of tests with 25 beekeepers using prototypes of the Varroa Controller were completed in 2009 and 2010.
Based on the results of these test, the treatment parameters were optimized and a new design of the Varroa controller was developed. The first series of the Varroa-Controller has been sold in Europe since June 2011.
