Hello, I don’t understand the hype around Oxalic sublimation with those electric vaporizers. It is as simple as just get a tealight under a metallic container with 2 Oxalic tabs.
The problem is the hive designs commonly used. Varroa do not survive in highly insulated hives that are also humid. Traditional hive design does not provide this. Hot and humid countries such as Cuba are naturally free of it. The bee pupate and hatch quicker in a hot environment allowing less time for the varroa mites to mature in the cells. Top bee entry and ventilation only are more humid and the varroa do not like that. Why remains a mystery, but that is the case. The problem in a cool country lies in the hive designs, having all the environmental integrity of a cardboard box,......mostly.
This is so blatantly wrong on so many levels. Bees control the levels of humidity in the hive. The reason most places like Cuba and other less developed countries don’t have issues from Varroa is because they could not afford to spend hundreds of dollars of big Pharmaceuticals treatments. The local populations have been heavily selected for resistance and given they can swarm year after year around it is faster than us that have seasons. Heat has greater effect then humidity on mite populations.
As soon as humans intervene it's No Longer Natural,this is a good video for beginners, but experienced beekeepers will find a ton of bs statements that from experience know just aren't true.People need to stop regurgitating information and start only teaching what they know by their own experience to be true...and then alot of statements would be withheld..
