John, >>...mostly from Bweaver stock... About 30% of my hives have not been treated in 2+ years... How did you treat the other 70% for varroa? How many Weaver queens do you have and have any of those hives turned out *hot*? I've had hives go 2-3 years w/o treatment followed by an epidemic of shrivelled wings. I hope you continue to experience low mite loads. Regards, Waldemar Long Island, NY -- Visit www.honeybeeworld.com/bee-l for rules, FAQ and other info ---
