The best way to prevent beetles from appearing in the first place is too make sure the humidity and temperature are kept on the low end. A temp/humidity level of 62°/67% is perfectly acceptable and will also help prevent mold. The main cause for beetle infestation is too much heat and/or humidity. They LOVE it. (It’s actually the larvae that feed on the tobacco.) The only thing that kills them dead is COLD. If you find that you do have a beetle problem, put all of the cigars from the infected humidor in a sealed plastic bag and place them in your freezer for three days. I say “ALL” because if you find one cigar that’s been attacked, you can assume the others may follow. Freezing the cigars will kill the beetles and their larvae and prevent the problem from spreading. When you take the cigars out of the freezer, don’t put them right back in the humidor. Put them in the refrigerator for one day to avoid shock from the temperature change, which could cause the wrappers to split. Before you replace them in your humidor, wipe the empty humidor with a clean cloth lightly dampened with distilled water. DO NOT use any cleaners, bug spray or disinfectant. They’ll just ruin the wood and give your cigars a foul taste. To help prevent the beetles from returning, purchase a good quality digital hygrometer/thermometer as the thermometer is very accurate. Also, make sure the room in which you keep your humidor is not subject to extreme changes in temperature. Don’t place the box in direct sunlight and check your humidifier regularly.
