Use of Acetic Acid to fight Nosema. Just a cautionary note! When using acetic acid do not let it drip onto concrete as it eats it away. I fumigated some hive in a big black garden sac/plastic bag but there was a tear in the bottom. As I poured the acid onto the pad must have dripped some - made a real mess of the drive outside my garage.
