As the forum is a little quiet at present, thought would start thread on Oxalic acid sublimation this particular winter. I would normally be thinking of sublimating my national hives, nadired with a super, at the end of the month with 1.5g oxalic acid dihydrate. There are two issues, firstly here in the south we have not had a frost yet and day time temperatures are up to 15˚C. Hence rather uncertain when they are likely to be bloodless to do single treatment. Secondly, I bought enough chemical grade oxalic acid (800g for £5 including postage) to last me a generation a 3 or 4 years back but now expected to use Api-Bioxal at 2.3g per hive equates to essentially 2g oxalic acid dihydrate. A 35g packet will treat about 17 hives by sublimation at cost of about 65p each rather than 2.5p. I clearly have bought Api-Bioxal to use legally but mark up on the oxalic acid is staggering considering the 35g packet Api-Bioxal at about £11 contains about 11p worth of oxalic acid dihydrate.
