Re: Oxalic acid fogger
I don't understand Croation, but the titles are something like control of treatment smoke gun (Google translate). One of the comments in the second video mentions Amitraz.
I entered oxalic acid in English and got oksalna kiselina and don't see anything in the comments that resemble that term.
IF you could vaporize a solution of OA powder in water with a insect fogger, I would be really interested, but somehow I don't think this is what they are doing.
