Oxalic Acid Treatment

Oxalic Acid Treatment

Oxalic Acid Treatment

Oxalic acid is extremely effective for the control of Varroa in brood free bee colonies. When applied properly, the three forms of application, spraying, trickling and vaporizing, have an efficacy of more than 95 %. A three-year study showed that the natural content of oxalic acid in spring honey is not increased. Thus, no residue problems are to be expected. The three treatments have shown a good bee tolerability and thus do not significantly differ in this respect from the untreated control.[1]Agroscope.  http://www.agroscope.admin.ch/imkerei/00316/00329/02081/index.html?lang=en accessed 03/12/2014
