You have a common problem. First, make sure that your humidor is being kept at or below 68 degrees F. Next, if you smoke a cigar, and you see one of those pesky buggers rolled in, smoke away. You've probably smoked many an elf larvae before, and will again. Finally, after you rid yourself of these pests, (Just a hunch, but they should be gone by December 26th) refreeze everything.
I wasn't going to say anything, but I felt the need to let you know. That looks fake. Sorry!
