I’m sure you’ve heard about the appearance of small worms inside coffee makers, inside packages of coffee beans, and even inside coffee pods. It may seem unbelievable, but worms can end up in our coffee makers one way or another. However, it is important to separate fact from fiction in this matter.
In this article, we will analyze the issue of worms in coffee makers and differentiate between what is a myth in this whole matter:
- On the one hand, we will explore the conditions that allow the development of worms in a coffee maker and how to prevent them.
- On the other hand, we will identify the factors responsible for the appearance of worms and what to do to keep the coffee maker free of worms.
What is the myth about the presence of worms in coffee makers?
Worms can appear inside a coffee maker, although it is important to point out that the presence of worms does not always mean that they have grown inside. Most of the time, worms usually enter through coffee contaminated with small insect larvae, which are not worms.
But the chances of worms appearing inside a coffee maker or a package of coffee beans are small. The problem is that we love exaggerating everything that is out of the norm. Therefore, if you find a little worm in your coffee maker, it is worthy of publication on all your social networks.
In short, although the idea of having worms inside a coffee maker may sound alarming, the chances of this happening are negligible.
What is the truth about the presence of worms in coffee makers?
We have already said that it is unlikely that worms will appear in a coffee maker; however, it is possible. There are two different possibilities for worms to appear inside a coffee maker:
- They may have ended up there when coffee, milk, or other related products containing them were added.
- That they have grown inside if the conditions are ideal for them.
In my experience, milk residues left inside the coffee maker and not properly cleaned are the main cause of the maggots’ appearance. The humidity and temperature conditions combined with a perishable product such as milk are ideal for developing these tiny living beings.
Look at this Nespresso Citiz&Milk that I recently fixed and how it was infested with maggots in the internal area where the milk accumulated:
Keeping the coffee maker, the milk system, and the surroundings clean will prevent worms from appearing. Storing the beans in an airtight jar will prevent worms from entering through the coffee.
Good practices to keep the coffee maker free of worms
One of the most effective ways to keep the coffee maker free of worms is to store coffee beans and ground coffee in an airtight container. This helps to avoid contamination and keeps potential pests away. It is also essential to ensure that the beans and ground coffee are stored in a cool, dry place.
Another important practice to keep the coffee maker free of worms is to clean and disinfect it regularly. This includes not only the exterior and interior of the machine but also its milk system if it has one (Steam wand or Aeroccino).
I recommend doing a superficial cleaning after each use and deep cleaning at least once a month. Ensure you use the right cleaning products and follow the cleaning instructions in the user manual.
It is also important to consider any odor or appearance indicating a worm infestation. If you notice anything suspicious, immediately clean the machine and its surroundings and inspect the coffee grounds.
Look at the dirt and mold that automatic coffee makers accumulate in the coffee grounds compartment, the perfect place for larvae to thrive:
✔️ By following these good practices, you can prevent worms from taking up residence in your coffee maker and ensure that you still enjoy a fresh cup of coffee, but without the source of protein in the form of worms 🤣.
