Hi all:
Received this question over on the OrganicBeekeepers list and need a formal answer but so far, nothing.......can someone help here with references?

Does anyone know when formic acid is used against Varroa mites and you
use plastic frames in the boxes, if the acid can react in any way with
the plastic and create and bad gas/chemical for the bees?


Also, in thinking, would it react with various queen cell cups, wax over plastic like durigult?  Since plastic does outgas, and plastic does breakdown (floating in ocean and in landfills so noted). 

What about other acids used in hives also?
