Rough atempt at oxalic Vaporization box

[RoofTops]

(Yawn). I use a 50p plastic syringe, 7.5g of oxalic acid dihydride, 100ml of warm water, 100g sugar. Each hive takes less than a minute. What is difficult about that?

As Finman has said many times, vapourization was one of the first methods used for applying OA - until trickling was discovered.

don't worry - same problems in other countries at this time of year:

trickling takes 20 sec.
But KISS is best - like don't bother unless they need it. There are other (and possibly better) ways to control the mite.
