There are few sights more depressing for a cigar lover than opening a cherished box of Havanas only to find tiny holes running through the wrappers. Sadly, this means your cigars have fallen victim to Lasioderma Serricorne — better known as the tobacco beetle.
These pests are the bane of the cigar world. Small, discreet, and destructive, they can ruin a prized collection in weeks if not dealt with properly. Here’s what every UK cigar smoker should know.
The Life Cycle of the Tobacco Beetle
The average life cycle of a tobacco beetle is 45 to 90 days, depending on temperature and conditions. That means a single infestation can spread rapidly through a humidor or cabinet.
- Eggs – Often survive standard fumigation or storage.
- Larvae – The most destructive stage, lasting 5–10 weeks. They bore through cigars, eating tobacco and leaving trails of fine brown dust.
- Pupae – Dormant, waiting to hatch.
- Adults – Live about a month, during which they mate, lay eggs, and start the cycle again.
Spotting the Signs
It isn’t always easy to tell if beetles are present. Sometimes larvae haven’t yet broken through the wrapper. Key warning signs include:
- Fine brown dust inside the box hinge or on the foot of cigars.
- Small round holes in the wrapper.
- A shower of tobacco dust when tapping a cigar on the box lid.
If you see any of these, assume there’s a problem.
What to Do If You Find an Infestation
- Isolate immediately – Place the entire box in a sealable plastic bag.
- Freeze, don’t spray – Insecticides will kill the beetles but render cigars unsmokeable. Instead, place the sealed box in the deep freeze for four days.
- Thaw gently – Move the box to the fridge for 24 hours before returning it to room temperature. This prevents wrapper cracking from sudden humidity change.
The cigars may not be perfect afterwards, but many can still be smoked acceptably.
Prevention Is Better Than Cure
The long-term solution, as the Voges Tobacco Encyclopaedia puts it, is “scrupulous hygiene and ruthless removal of infected cigars.”
Additional measures include:
- Temperature control – Keep cigars at 16–18°C. Beetles thrive above 21°C.
- Beetle traps – Companies such as Fuji in Japan produce pheromone-based traps that won’t eliminate an infestation but can confirm whether one exists.
- Proper sourcing – Never buy cigars from Havana street sellers or unreliable online shops. Counterfeits are notorious carriers of untreated beetle eggs.
The EMS Advantage
As John Darnton of Hunters & Frankau has explained, most UK smokers will thankfully never encounter tobacco beetles. Why? Because EMS (English Market Selection) Havanas are checked meticulously.
Every box imported into the UK under EMS is opened and inspected, ensuring that any beetle issue is dealt with before cigars reach the market. Combined with storage in carefully controlled conditions, this makes buying EMS-stamped cigars from trusted UK retailers the safest choice.
Final Puff
Yes, the thought of a beetle chewing through your prized Cohibas or Montecristos is horrendous. But don’t panic — infestations are rare in the UK, and EMS quality control adds an extra layer of protection.
The key lessons? Keep cigars cool, buy from trusted EMS retailers, and act fast if you see signs of beetles. Do that, and your humidor should remain safe, sound, and beetle-free.
