Oxalic acid vaporizer (JB200) for honey bee mite control

NOTE: I am now doing a single treatment late in the year when my capped brood is largely minimal and do not recommend multiple treatments. I then do another treatment prior to the spring before the queen starts aggressive laying. Instructions on how to use the JB200 oxalic acid vaporizer for treating honey bee hives for Varroa mites. Also has some details of building the cable for the 12V battery.
