Just my .02  
CCD seems to be a bit less a problem 
farthur north. 
I have 2 yards, 1 & 2 hrs NE of Toronto 
The south yard had 100% CCD 
The north yard none(CCD), but 1 loss was 'suspicious',  
bees more active (late) than they should have been.  
All loss was early in winter (15% at north) 
The nearest other BK (south) lost 10/11 
The 11th is very strong, will it survive? 
 
The only common factor I can see is skunk (visits) 
maybe its:  sick skunk -->t-mite -->restless 'itchy' bee??? 
 
Did anyone using formic late summer have any CCD??? 
please reply, negative info as valuable as positive 
 
On a more cheerful note I'm still pleased with  
my electric heaters, all the nucs survived 
They are running as I type. I did stuff a  
pollen frame into most(nucs) since they had none 
No pollen here yet 
(see archive for details re heaters)
