Re: Oxalic/glycerin on cellulose mite treatment
"Dispensing O.A. in cellulose strips, without water presence but only with
crystals of organic acid gives unsatisfactory results especially when the level of humidity
inside the nest is not sufficient to moisten the O.A. crystals.
Oxalic acid soaked in cellulose strips did not give acceptable varroa control under spring conditions in central Italy.
Control was better for winter treatments under broodless conditions. The reason for its poor efficacy is possibly due to the modality action of O.A.
This paper also has shown the trickling and the evaporation of O.A. are the most effective ways of it to control varroa (Graph 2)."
So if you somehow can make the oa powder fine enough to stick on the bees then you might have a winner.
I wonder what is its effectiveness if you can combine the fine sugar and oa powder together to shake on the bees?
Could potato powder or any other tuber powder works with the oa powder mixed in? Will agar powder harm the bees too?
Don't mix foreign bees into a virgin hive. She might get balled 100% of the time! When will you ever learn, huh?
