What can you do if you find your cigars infested with the tobacco beetle? Research has shown that your microwave may be your best defense in destroying the tobacco beetle larvae. Before using your microwave, remove and dispose of any infested cigar from your collection. The rest of your cigars can be treated. In order to rid the remaining of your collection of this pest, you should make sure to microwave your cigars together, never individually. Microwave them for about three minutes. After being warmed, immediately place the cigars into the freezer. After freezing them for 24 hours, remove them and allow them to thaw at room temperature. After they have thawed completely, place them in a humidor. This treatment has proven effective in removing the presence of the tobacco beetle. Before removing a cigar from the humidor to be smoked, examine each cigar individually. If the cigar shows no evidence of infestation, it is safe to smoke.
