I bought a "grab bag" of sticks from a big online retailer last summer and in going through the bag I found 4 sticks that had beetle holes going through the cellophane and into the cigars. I immediately took all of the sticks and popped them in the freezer for overnight, just to be safe.
The other time this happened to me it was a box of Twist Robustos - 4 sticks had beetle holes in the cello and the cigars. The rest of the box was fine, and I called Rob to let him know, just so he could check the rest of his stock. Rob immediately replaced the bad sticks without me asking. And I continue to be a customer at Rob's shop, mainly because I know he stands behind his products!
I had not been a proponent of freezing cigars, but after reading Silverfox's thread on damage, I freeze virtually every box that I purchase.
