I’ve never had a beetle problem (…knock on wood…) but since I don’t have any regulated temperature & humidity controlled storage, I tend to freeze more often than not. I leave the cigars in the freezer for at least 4 days, sometimes 5 with 2-3 days in the refridge before and after.
Why so long in the freezer?
I read something online that household freezers aren’t normally cold enough to kill the eggs in 72 hours and recommended at least 96. I tried looking for the article again but to no avail. I also take into consideration if the cigars are in bags or boxes. Boxes stay in for at least 5 days. At any rate, that’s what I do to prevent beetle infestation.
