<<<I have used FGMO with no other chemicals for 2 years This dead horse revives from time to time as new people take up beekeeping and look to the internet for advice on varroa control.What is missing from this debate is hard scientific experimentation with controls.So I will add my unscientific results to further muddy the waters.I experimented with fgmo last year,fogging every two weeks on hives that showed light infestations in spring.By August every one of those hives were crashing and couldnt be saved.Now the reccomendation is once a week fogging.My fogger is collecting dust on the shelf. :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: -- Visit www.honeybeeworld.com/BEE-L for rules, FAQ and other info --- ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
