Treating your cigar humidor after a cigarette beetle infestation

What is Lasioderma?

The Lasioderma serricorne, commonly called cigarette beetle or "tobacco worm," is a small insect about 2 to 3 mm long. Recognizable by its humped thorax and smooth elytra, this insect often goes unnoticed. The larvae of the lasioderma closely resemble those of the drugstore beetle, another pest insect. Their life cycle is fast, about 25 days at a temperature of 30 to 35°C, but they do not survive below 17°C.

This insect is very mobile, capable of flying and infesting various products such as tobacco, cereals, dried fruits, or even spices. If you notice small perfectly round holes, similar to pinheads, on your cigars, this may be a sign of an infestation by the cigarette beetle.

Infestation by the cigarette beetle in your cigar humidor

The cigarette beetle is a formidable enemy for cigar enthusiasts. Indeed, the insect devours the cigar from the inside, making the first signs of infection difficult to detect. If nothing is done, the infection can spread quickly throughout your humidor, reducing your precious cigars to dust. It is, without a doubt, one of the worst threats to a cigar collection.

How to prevent and treat a cigarette beetle infestation

Steps for treatment in case of infection

If you notice the presence of lasioderma, here are the emergency measures to take:

• Isolation of infected cigars: Place them immediately in an airtight plastic bag and destroy them (by burning or discarding them).
• Freezing healthy cigars: Place the uninfected cigars in Ziplock-type bags and put them in the freezer for three days. This method kills larvae and eggs, which cannot withstand very low temperatures.
• Cleaning the humidor : Carefully vacuum to remove larval residues. Then, disinfect the humidor with an odorless product. Consult your pharmacist for suitable solutions.
• Freezing the humidifier : If possible, also place the humidifier in the freezer to prevent any cross-contamination.
• Progressive defrosting : Take the cigars out of the freezer without opening the bags and let them thaw slowly in your humidor for three days before handling them again.

This process is essential to try to save part of your collection.

Prevention against infestations

It's better to prevent than to cure.

Here are some tips to protect your cigar humidor:

• Use a lasioderma trap. These devices attract insects through nutritional baits and pheromones, allowing for rapid detection of any infestation.
• Maintain a stable temperature in your humidor, ideally below 20°C, to limit the risk of proliferation.
• Avoid storing unchecked cigars directly in your humidor. Always go through a freezing phase if you bring them back from abroad.

Specialists also offer already frozen cigars, which considerably reduces the risk of introducing insects into your collection.

The origins of lasioderma infestation

A lasioderma infestation can come from cigars brought back during your travels to producing countries such as Cuba, Dominican Republic or Honduras.Unlike cigars imported by official distributors, which are systematically frozen before being marketed, these cigars may contain eggs or larvae.

Before storing your cigars directly in your humidor, make sure to freeze them for three days to eliminate any possibility of infestation.

Conclusion

The cigarette beetle is a serious threat to your cigars, but with increased vigilance and proper preventive measures, you can protect your collection. Consider investing in a cigarette beetle trap and properly managing the temperature of your humidor. If an infestation occurs, act quickly to limit the damage.
