I know I may step on some toes with this but when I get my bees I am going to try to let the bees do their own thing, stay away from poisons and treat matters with natural things as much as possible. Clean with tea tree oil etc. We have become so dependant on medicines and chemicals that it is out of hand. It is killing our bees, our wildlife and is killing us slowly. I think if we keep our bees healthy as possible we wouldn't need that harsh stuff. Before man stepped in, they collected their honey and did fine. (Of course I don't know the first thing about bees but the more natural something is the better it is too.) How can you go wrong with that?
