Hi to you all. I am new to forums and its my first full year of beekeeping so please be gentle. I would like to vaporise oxalic acid to treat for mites. I think it is more of a commercial approach but makes sense in cold wet windy weather. I have seen various home made gadgets that work in a fashion but there are always better ideas out there. Does anyone have a reasonably priced method. I thank you for any help, and may I also say congratulations on your forum.
