Hi Mark, A tobacco smoke knock-down was the official method of searching for varroa in the UK until very shortly after it was found. Many people who had been using tobacco without finding mites started using Bayvarol when it was released and promptly found many hundreds or even thousands of mites. Here at least, tobacco smoke is now generally believed to be discredited.
