Re: Started fogging today.
Frankthomas - you ask a very interesting question. GLOCK diligently fogged his hives, but still had to treat with oxalic acid, and he reported his results in this thread for everyone's benefit. Yet people reading this very thread still want to fog their hives.
My guess on why people want to fog is because it feels good: you don't put those nasty chemicals in your hive, you are physically doing something against the varroa each week, fogging makes lots of noise and smoke, so it must be doing something. The fogger walks away from the hive feeling good like he just really socked it to the varroa. It all seems so good, how could it not work? The next step is easy at that point; just ignore the fact that no reasonably well done study has shown fogging to work.
