There's a couple of products available for repairs. I've only used it on a few beetle holes and 1 or 2 unwrapped premiums ...
(1) Cigar Dr
(2) Cigar Repair
It's the same vegetable based adhesive used in making/rolling the cigars. Dab (small amount) under the wrapper leaf and it will fix the cigar (smokable condition) without affecting the taste.
Or like mentioned above, go find liquid CERTO at your grocery store - liquid fruit pectin available in the jelly making section. Liquid is better - no mixing or just mix a small amount of the powered and store it in a film cannister and keep it in the fridge (keeps for about 5-6 months. To fix badly damaged cigars, paint pectin over the areae/hole, and place a "patch" of wrapper leaf (available at most cigar stores OR use any dog rocket with a CT Leaf. Wait until the pectin dries - then smoke. One note: the fruit pectin has no odor - but you might get a hint of 'sweetness' in your puffs - better than losing the whole cigar though.
Just my humble opinion.
On another note: CIGAR BEETLES
As you all know, I recently found these bastards in my Avallo - to no avail - I couldn't catch them all and didn't want to 'deep-freeze' all of my premiums just for a 'precautionary' measure. I did freeze all that had holes in them (sealed them in 1 gallon Ziploc freezer bags) for a week - then 5 days in the fridge, and then went to re-introduce them into the Avallo. MORE HOLES though ... SOOOOOOOOOOOOOOOOOOooo
I raised my humidity to 74% at 70 degrees - get them moving - and then placed a dish with 2lbs of Dry Ice in the Avallo - as the dry ice evaporated - it created a 'fog' effect in the humi and essentially 'fumigated' and/or froze (created a perma-frost effect) all through the inside. I added dry ice chunks 2x a day for 5 days about 2lbs each time and have yet to see any more beetles.
Mad Scientist? Maybe - but I was desperate and it worked (been 4 months now) and I've not had them back. Sadly enough, I should have done this with my premiums also - they would have faired better than the plastic bag & freezer routine.
- just my .02
