Hello everybody, Thanks for your replies regarding temp and varroa control. I’m glad to hear about researches without using chemicals. What I wanted to say, was not temperature high enough to kill the varroa but the application of temperature enough to irritate the varroa to get them to drop. And by applying this on a regular basis could control the varrroa population in the hive to a low level for it not to be counterproductive.
