Kate: I apologize for my bluntness, but you need some STRONG advice.
In all history, never have wax moths killed a colony of bees.  The adult
flying moth lays eggs in the crevices of dark spots of the hive and these eggs
develop into larvae (white wiggly worms).  These worms have to eat to become
adult flying moths.  However, contrary to many beeHAVERS, the diet of these
larva is NOT honey, NOT wax, NOT bee brood, and surely not live bees; but
rather the PUPAL COCOON of a developing honey bee.  Some people have called
these cocoons a bee "afterbirth", which is a great example of anthropomorphism
that far too many so-called beekeepers have today.  When a bee larva's cell is
capped with wax, the larva spins a cocoon to develop through its pupa stage
before it emerges 11 days later as an adult bee, and this cocoon which is a
protein source is left behind glued to the cell wall of the BROOD frame.  The
wax moth larva (worm) tunnels through the wax cell walls of a BROOD frame to
eat these cocoons.  They will not damage a honey super frame that has never
had brood laid in it.
    So why were your colonies have wax moths?  Your colonies were in serious
trouble long before the wax moths took over.  The bees probably had some
disease, which had materially weakened them, such as: tracheal mites, varroa
mites, foulbrood, nosema; or they might have become queenless and were unable
to raise new queens.  My strong hunch is the bees were infested with varroa
mites- varroa jacobsoni.  Had you treated with Apistan strips?  Had you
treated with menthol in August to kill tracheal mites?  Had the bee inspector
checked them for American Foulbrood?  ALL OF THESE TREATMENTS must be done
EVERY YEAR, EVERY YEAR, EVERY YEAR.  When did you last observe BROOD in these
hives?  In Lancaster, every hive should still have brood in it until November
telling you that the colony is queenrite.
     If you are not upset by my BLUNTNESS, I will be happy to advice you for
further action, and "get you on the road to future success", but I will leave
you with a positive statement:
      YOUR BEES WERE NOT DESTROYED BY WAX MOTHS!  They were destroyed or badly
weakened by something else that allowed the wax moths to take possession of
the mess that was left.

why I offer my free knowledgeable help.
