I have absolutely zero proof of this, except for my experience with beetle larvae among troop smokes that have passed through here.
They'll go right through cello.
I have never, not once, seen them drill through a finger bag. That's despite seeing a number of drilled smokes in finger bags that have eaten uncelloed smokes and celloed smokes alike.
(My guess is that they'll eat cellophane because it is made of plant material and will not eat finger bags because they are pvc or petroleum based? I'm really not sure what finger bags are made of.)

I use tons of single finger bags for all those smokes I gather up here and there. I use them in my travel humidors and drawers.
I don't put all my smokes in them, by any means, but I feel it's good practice, and could stop a problem if it ever did happen to arise.
It's something to talk on that goes to storage, and if there's truly anything to it, it's another way to protect smokes.

Maybe Adam and Hugh can weigh in on this. They're also seen gazillions of cigars go through their hands and may have witnessed what I mention.
