WHILE TRICKLING OXALIC ACID IN SUGER SYRUP IF THER IS EGG AND LARVEA WITH NO CAPPED BROAD WILL IT WILL BE EFFECTIVE WITH NO ADVESR EFECT ON EGGES AND LARVEA?
I do not know what happens. I suppose that it is harmfull to larvas.
But when you have this situation, you may prefer this concept:
1) If you have in some hive drone larvas, they are jut capping, give those to that hive and mites prefer rush into drone cells
2) Take away first frame of capped brood, because after a brake mites goes into first brood bees are capping. Uncap frame and wash them with hose sprey.
3) Make a nuc from those first brood frames and let them emerge and then you give cure.
