Duration of Oxalic Acid on Bees

[Eyeman]

Sorry if already posted. Experiment by Randy Oliver on dead bees exposed to different delivery methods & additives to Oxalic acid. He measured the ‘acidity levels’. Adding sugar caused the acidity to rapidly decline- think Api Bioxal. Vaporisation persisted the longest 90% at 4 days.

if they're dead, it means very little

Which is why we vape every 5 days

So, excuse my ignorance, but is it better for the acidity to last longer or not?

Researches made from dribbling mixture of oxalic acid has been made over 20 years ago. Since then method has been used.

Dribbling works when the colony does not have capped brood.

What is Randy Oliver now researching?

Problem in California, where Randy Oliver lives, is that the day temp on area may be 25C September. Randy has not got good results from trickling.

As you know gasification of oxalic acid has given good results. This method and its variations has become now popular in Finland too.

Well the popular theory is that it enters the mite through its feet and then moves into the bloodstream and disrupts its metabolism, seems to be a 'physical' thing so I reckon the longer the acidity lasts, the longer it blasts the mite population. So a good thing....probably.

Alas as we are all using the only licenced OA treatment flavoured with sugar shorter intervals may be required.

So do I

if you are following the guidelines on 'licenced' OA, then you should only be using it once - if you multiple vape with it, you are still in breach of the regulations so you may as well save some money and use the good stuff

Keeping meticulous treatment records for five years is also becoming tedious and has almost filled my filing cabinet....
