Thanks to those involved in the replies , I read the material
so then
Juanse Barros J. writes:
If the queen is laying i put
amitraz, if not i dismatle the  nuc.

from Randy Olivers suggested reading:
"The downside of amitraz is that it is somewhat more toxic to bees than  
fluvalinate, and shuts 
down the queen’s egglaying during treatment  (Henderson 1998; pers comms).  
This is not 
surprising, since Bloomquist  (1996) states, “Amidines cause an 
overstimulation of octopaminergic 
synapses  in insects, resulting in tremors, convulsions, and continuous 
flight behavior in  adult 
insects. Moreover, these compounds have the ability to cause a true  anorexia 
in insects and also 
suppress reproduction.”

My question then is:
How good are these queens? 
or should we not give it much thought?
