As Craig61a mentioned in his post;
“Yes, freezing does kill the eggs, larvae. They hatch when the temp get above 80F.”
That 80F number is a good one to keep in mind. With thousands of cigars in my humidor, moving to the Southeast coast of NC posed a slight concern as we keep our thermostat around 78F in Summer, and occasionally on very hot days, the walk-in closet/humidor can bump to 80F or a tad higher! I’ve been checking regularly and so far, so good.
If you have the ability to maintain safe temp in your environment, hopefully you’ll avoid issue - aside from transit time temps as mentioned by Russ. I’ve seen these little guys decimate a cigar shop ?
