Freezing cigars to combat beetles
Every cigar enthusiast’s nightmare is discovering Lasioderma serricorne, the infamous tobacco beetle, near their cigars or humidor. Their presence signals an outbreak that could compromise your cherished collection. But fear not—armed with the right techniques, you can effectively eliminate this threat.
Understanding the Tobacco Beetle
Why Do Beetles Infest Cigars?
Cigar beetle larvae are an unavoidable part of the tobacco curing process. Manufacturers employ treatments like freezing or fumigation post-rolling to eradicate these pests. However, if these processes are incomplete or mishandled, surviving larvae can hatch under favourable conditions, typically high temperatures (above 22°C/72°F) and humidity levels over 72%.
Signs of an Infestation
One tell-tale sign of cigar beetles is tiny, pin-sized holes in your cigar wrappers. If you spot these, immediate action is crucial. Damaged cigars should be discarded, as they can contaminate the rest of your collection.
Freezing: The Best Method to Eliminate Tobacco Beetles
Freezing is the most reliable way to halt a beetle infestation. Done correctly, it kills larvae and prevents further outbreaks without harming your cigars. Follow these steps for a beetle-free humidor:
Step 1: Seal Your Cigars
Place your cigars in a clean, airtight container such as Tupperware or a sturdy Ziplock bag. This prevents external odours or flavours from permeating your cigars during freezing.
Step 2: Cool Before Freezing
To minimise wrapper stress, cool your cigars in the refrigerator for a few hours before freezing. However, some experts, like Marc André, recommend rapid freezing to ensure the larvae do not produce glycol, a natural antifreeze that could help them survive the freezing process.
Step 3: Freeze Your Cigars
Once cooled, transfer your cigars to the freezer. While many aficionados freeze them overnight, even a few hours is often sufficient to kill beetle larvae.

Step 4: Gradually Warm Up Your Cigars
After freezing, move the cigars back to the refrigerator for 12 to 24 hours. Gradual warming prevents the delicate wrappers from cracking. Never use a microwave or direct heat to defrost your cigars.
Step 5: Return to the Humidor
Once the cigars have acclimatised to room temperature, return them to your humidor. Regularly monitor the collection to ensure no further signs of beetles appear.
Preventing Future Infestations
While freezing is an effective solution, prevention is always better than cure. Maintain your humidor at a stable temperature below 22°C/72°F and a humidity level under 72%. Regular inspections and good storage habits can also minimise the risk of infestations. Buying from trusted sources can also help and in my experience, the beetle problem is bigger with Cuban cigars than with Non-Cuban cigars as new world producers seem to have better ways to kill larvae.
Patience Pays Off
As tempting as it may be to light up a cigar immediately after treatment, take the time to let it recover. A high-quality cigar deserves careful handling—after all, it’s not a quick meal to be rushed.
