No assumption, rather the observation that 2 yr old dead-out boxes
restart the problem.  Nearly evey BK with "ccd experience" will agree

And anyway the few posts previous are debating if it is possable to eliminate
nosema from any yard,  I'm inclined to think not

My bees have had 5 seperate tests showing zero nosema
(over 1.5 years).  Kind of pointless to feed fumigillan in this case

However when I bought a new queen I used up almost a whole
(small) bottle on that nuc (as well changed cage & no attendants)
