Dan,
Even if the SHB gets established in Canada I do not see ever becoming a 
problem. California imported thousands of hives infested with SHB from the 
east coast sell out of a very large commercial beekeeper in 1998. SHB can 
be found in those hives but have NEVER caused a serious problem. I know 
because a very close friend sold the hives and another friend bought the 
hives.
The major players in California simply say:
"two kinds of beekeepers in California. Those with SHB and those going to 
get SHB".
In my opinion only queen breeders which refuse to go to 4-5 frame nucs 
instead of using the old mating nucs (and a cup of bees) will have 
problems. Last season a friend queen breeder complained as he has 10,000 
very small mating nucs and only 200 five framers. I told him three years 
ago he better start thinking of dumping the small nucs! In short a cup of 
bees can not protect brood comb from SHB no matter how small the entrance.

I have watched the SHB problem closely ever since I drove to Florida in 
1998 to see up close the *first* documented case.
