ughh, I had hoped I never had to ask about the dreaded cigar beetle, but today I found them. My question is, how did they get there? Here's the situation. I've had my entire stash in a coolidor and inside separate cigar boxes for 2.5 years now. During that time, the temperature has not fluctuated above or below 67-70 degrees fahrenheit and the rh has always been a steady 65%. I also test and re-calibrate both of my hygrometers once a month. The beetles were discovered on 2 gran habano 2002's, which have been in the cooler since march of 2014. No other cigar has been effected. I have taken the necessary quarantine precautions since the discovery but that really doesn't answer the mystery of how this happened. Even more strange, 4 days ago I pulled cigars from the same box, and there were no beetles present on said infected sticks.

So I guess my question is, how would a beetle hatch on 2 sticks in a completely controlled environment, when they have already been resting in the environment for 18 months?

Thanks for any input. The plus side is, at least it was a couple of cheap smokes that got wasted and not the good stuff.
