I'm a hobbyist beekeeper trying to grow into a sideline business in Central Fl with 10 hives and went with trying Hopguard for my Fall mite treatments. I was originally planning on trying oxalic acid dribble but the Hopguard application seemed simpler and with less reported effect on brood laying. After applying Hopguard and then reading up a little more I went ahead and treated 3 times over 3 weeks which wasn't as simple as Hopguard originally seemed to advertise. Anyone out there with experience using hopguard vs. oxalic? Pros and cons from actual experience?
