If you want a bunch of them to absconded than yes.Is is OK to treat a new bee package just introduced into the hive with oxalic acid?
There used to be a German video about the rotary system of beekeeping where packages are sprayed with a solution of perezene (a fluvalinate) while still in the package box and left on check paper overnight before being united with their daughter colonies. The papers were then mite counted for queen rearing record purposes(I think).If I were going to do this...I think I would put the package w/queen inside the hive without releasing the bees. OAV them. Then later that day or the next turn 'em loose. I haven't done it but it would seem like it would allow them to settle down post treatment...while still in the package. Just a thought.
