Here in Anchorage, Alaska I have very rarely had a spring without some
     Chalkbrood.  It is cool and damp in the spring.  I have yet to have it
     amount to anything when the population built up.  I am refering almost
     exclusively to new packages.  I usually start about four new packages
     each spring, and only rarely have had any real success getting any
     significant colony through until spring.
 
     Unless bees showed a problem with Chalkbrood I would not be concerned
     about it.
