Hi Ted, hmm, losing two frames during the summer makes me wonder if the colony was small to begin with. In my experience, when hives are bustling there are enough bees to take care of the wax moth before it gets to be a problem. this year, in our area many of our hives were reduced to small colonies by the end of summer. So I had some frames effected by the wax moth as well. Caught them in time to get them in the freezer pronto.
