Unlike the Fab Four: John, Paul, George, and Ringo, the tobacco beetle, scientifically known as Lasioderma serricorne, is one beetle you don’t want to meet, especially in your humidor. This pesky bug’s eggs like to nestle themselves in tobacco leaves. After it hatches, the larva will ravenously eat its way through your prized sticks. So how do you stop them? A properly maintained humidor is the best defense against a beetle invasion. Make sure your humidor’s temperature stays under 73 degrees Fahrenheit (23 degrees Celsius), and in the 65-72% humidity range. The picture below shows a beetle hole, a sign that your cigar needs to be discarded.
