What are Cigar Beetles

If you are a cigar enthusiast, you might have heard about or come across cigar beetles. They are tiny insects that lay eggs on your cigars and ruin them in the process. The good thing is that they can be prevented. Here is everything you need to know about cigar beetles.

What are Cigar Beetles?

These are tiny insects that are rarely visible with naked eyes. They sneak into the tobacco and lay eggs during the production process. When the eggs hatch, the larvae eat the tobacco and poop giving the impression of blackish dust. When the cigar beetles burrow their way through the tobacco and reach the wrapper, they make round holes. By this time, the chances are that the cigar beetles will have multiplied and even moved to different cigars in your collection.

How to Detect Cigar Beetles?

Before checking at the methods that you can use to control cigar beetles, it is important to know how to establish whether your cigars have the beetle problem.

Black dust

This is the commonest sign that your cigars have been infested by the beetles. This should not be confused with the tobacco remnants that are commonly found at the humidor’s bottom. If the cigars have not been moved for some time, you only need to tap at the edge to see if there is tobacco dust. If a lot of dust comes out, there is a likelihood of cigar beetles infestation. The black dust is actually the droppings of the beetles.


If you notice small holes on the wrapper, the chances are that your cigars have been affected by cigar beetles. The holes appear as lovely pinholes because if you push a needle through, the puncture would look the same.

If you notice one or both of the above symptoms, the chances are that your cigars are under attack. Though there is not much scientific info about what would happen if one smoked them together with tobacco, no one would want the idea of pushing smoke of their poop.

Preventing Cigar Beetles

In order to stay free from cigar beetles, it is advisable to start by understanding what they are. If you find that the humidor is already infested, here is what to do:

  • If you establish that one of the cigars is affected, the chances are that even others are also infested. Therefore, consider removing all the cigars from the humidor, put them in airproof bags, and seal them. Then, put the bags in a freezer for about four days before returning to the humidor. The extreme cold help to kill the beetles and their eggs.
  • You should also consider cleaning the humidor. While the freezing will kill the beetles, those that might have been left in the humidor could still attack again. It is, therefore, prudent to clean the humidor and allow it to dry before returning the cigars.
  • One notable thing about cigar beetles is that they like high temperatures. Therefore, you can discourage them by keeping the temperatures around 70 degrees Fahrenheit. Besides, the humidor should be kept indoors in a place that will not raise temperatures.


Cigar beetles are some of the main threats to your cigars when stored in a humidor. If you can identify the beetles on time, it is important to take every precaution to eliminate them and keep the system secure. The above demonstration is ample to help keep your system free and ensure every puff delivers the anticipated flavor.
