How to Get Rid of Cigar Beetles & Tobacco Bugs
Lasioderma Serricorne
Cigar beetles, also known as tobacco beetles (Lasioderma serricorne), are a nightmare for cigar enthusiasts. These tiny pests can destroy an entire cigar collection if left unchecked. In this guide, we’ll cover how to identify cigar beetles, prevent an infestation, and eliminate them if they’ve already invaded your humidor.
Identifying Cigar Beetles
Cigar beetles are small, reddish-brown insects about 2-3mm in length. They thrive in warm, humid environments and are particularly active at temperatures above 72°F. Signs of an infestation include:
- - Small pin-sized holes in your cigars
- - Fine tobacco dust in your humidor
- - Visible beetles crawling on cigars or inside the humidor

How to Prevent Cigar Beetles
The best defense against cigar beetles is prevention. Follow these tips to keep them away:
- Maintain Proper Humidor Conditions – Keep the temperature below 70°F and humidity around 65-70%.
- Freeze Your Cigars – If you suspect beetles, place cigars in a sealed bag and freeze them for 48 hours, then thaw gradually in the fridge before returning them to your humidor.
- Keep Your Humidor Clean – Regularly wipe down the inside of your humidor to remove any tobacco dust or eggs.
How to Get Rid of Cigar Beetles
If you’ve discovered an infestation, act fast to minimize damage:
- Remove All Cigars – Inspect each cigar and discard any that show significant signs of beetle activity.
- Freeze the Infected Cigars – Place affected cigars in an airtight bag and freeze for at least 48 hours.
- Clean Your Humidor Thoroughly – Wipe down the inside with a dry cloth and vacuum any loose debris. You can also use isopropyl alcohol (70%) for deeper cleaning but ensure it dries completely before restocking.
- Monitor Your Collection – Keep a close eye on your cigars for the next few weeks to ensure no further infestations occur.
Cigar beetles can be a serious problem, but with proper prevention and quick action, you can protect your cigar collection.
Keeping your humidor at optimal conditions and regularly inspecting your cigars will help ensure a beetle-free smoking experience.
