I only found three posts searching the archives on the vinegar fogger and they were all on the 28th of May 2001. To look at the machine*vinegar fogger* (made by Honey Processors,LTD).you need first to look at vinegar. Vinegar relies on its chief chemical ingredient Acetic Acid to kill microorganisms I believe this is accepted truth from my high school biology. The proponets of Acetic Acid against bacteria claim: All carbohydrates contain the same chemical elements,carbon,hydrogen and oxygen. Acetic acid dissolves bacteria spores by breaking up carbohydrates in them. True or false researchers? The proponets of acetic acid against varroa claim: Acetic acid readily breaks down . the hard covering (Chitin) which is made up of calcium which is the hard shell of the varroa mite. True or false varroa researchers? The proponets of acetic acid for varroa control use the following example: An example of the effects of white vinegar(acetic acid) on calcium is the effect it has on a chicken bone. The bone turns to rubber. I plan to test this example. My attempts at catching one of the wifes chickens in the middle of the night with a hernia has resulted in dismal failure (kidding!). Is this example correct researchers? The points I have listed above are why I made the statement in theory the vinegar fogger should provide a certain amount of varroa control. If researchers will comment and say the two points the proponets of Acetic acid have made are *hogwash* then I will have to amend my position in the *vinegar fogger* discussion. Sincerely, Bob Harrison Odessa, Missouri Ps. Am I the only person in the world up in the middle of the night thinking about the vinegar fogger?
