But it is you who refuses to accept the facts. France and Germany have banned the use of clothianidin one of the neonicitinoid pesticides because of its impact on bees. Here is an excellent article regarding this issue.
Lastly your cheap shot against commercial beeks was uncalled for. We take great pride in maintaining healthy bees and the practices utilized by them for treatments of mites and other problems for years would not "suddenly" start killing off the bees. Additionally, as a commercial beek that does not utilize chemicals in my hives I resent the fact that you "assume" that all use chemicals in their hives. I know many that do not and the trend seems to be moving to more natural substances to maintain the health of the bees. (essential oils and supplemental feeding)
