LOL... I think it took me four hours to do 80 hives.
The time to treat this spring is approaching, I will see if I can get a time per hive/all hives.
Running two wands it takes me somewhere between three and four minutes per hive.. provided I don't get a phone call or interrupted etc. I can actually manage four wands. by the time I have run through the 4th it is time to pull the first and start over, but the conflict of cables everywhere and not being able to reach far enough etc I have found that two is fine for how fast/hard I want to work.
