I'm a 72 year old amateur beekeeper and for 25 years, had no problems. Suddenly I have lost both hives, one in Arizona and the other in Michigan. Both to Mites. There are on the market two treatments, possibly the same product, for treatment for mites. They are called "MITE SOLUTION" and "M-SOLUTION". Does anyone know anything about this stuff and I have some specific questions: 1) Is it effective 2) Is it safe to use during the honey-flow On another matter, I have tried numerous times to locate the queen, but have never seen her. Is there a tried and true system for locating the lady. None of the queens have been marked as my first hive in Michigan took care of itself for about 25 years including any requeening that may have been necessary. On another matter, I have a dificult time maintaining a good smoke and wonder what fuels are the most popular. The best I have come up with is some quite heavy burlap that smolders quite well, but there must be a better alternative. Thanks. Gordon N. Stowe
