Creatures like ants, are in constant search of provisions to feed their colony and a warm place to raise their eggs. And it happens, that your coffee maker is a good water resource and shelter for any ant colony.

Ants usually stay away from coffee grounds because it makes them lose their trail’s scent. If they don’t have any scent to guide them through, they become lost for some time or at least a little bit confused.

If you multiply that by thousands, that means a huge resource delay for the colony. If they are not careful enough, the whole colony might die. This is why ants tend to stay away from these deterrent smells.

Ants might hate the deterrent scent of the coffee grounds, but they do appreciate the nice water reservation and warm shelter your coffee maker can provide. These are the main points that attract them so much.

How Do I Get Rid of Ants in My Coffee Maker?

1. Remove Any Visible Ants Out

First things first, you need to clean your infested coffee maker asap. You can either vacuum it or you can take it to your kitchen sink and shake them out in there. To prevent ants from running away to other places, keep the water running and let ants fall into it.

Do not submerge your coffee maker into the sink water, doing that will damage any electronics that are on the inside of the coffee maker. Water and circuit boards do not combine well.

2. Move It to a New Place

Another thing you need to do is, interrupt the ants’ pattern for a good while. After you’ve cleaned your coffee maker, if you put it right back, ants will just follow any scent left behind by other ants and they will infest your coffee maker again.

You need to move it elsewhere for some time, this will interrupt the ants’ signal that there are resources available in that spot. Move your coffee machine to a new place and make sure there are no ants coming out from it.

This will ensure that the remaining ants won’t alert others to the new placement of your coffee maker. Even if one ant can return, it will be able to tell others that information. If no ants return, your coffee maker is secured.

3. Clean Your Coffee Maker Well

Getting rid of the ants’ pheromones from your coffee maker is another important step to take. You should clean your previously infested coffee maker, in order to prevent future ant visits. When ants infest something they will leave pheromones behind, this helps other ants to identify that there is a valuable resource in there.

When you clean your coffee maker machine, you are ensuring that any ants’ residues are gone for good. This guarantees that there are no scents to signal other ants nearby.

4. Use Natural Repellents to Clean It

You can use lemon juice distilled in water to clean your coffee maker, this will act as a natural repellent and will keep ants away. As an alternative solution, you can also use distilled vinegar with water.

Don’t mix lemon juice and the vinegar together as their high acidity may damage your coffee maker esthetic’s. Use a clean cloth to apply the solution and let it dry. The strong smell will dissipate after a few hours.

5. Keep It Always Clean

The best strategy to keep your coffee maker machine always free from ants is to practice active prevention. If you keep it clean and waterless (when not in use), you will guarantee that ants will lose interest in camping around and in your coffee maker.

Always change old filters and keep your coffee recipient clean from anything that might attract ants to it. It is a good idea to clean the grabbing handle if you touched something sweet and stayed stuck to it.

Do not forget to empty any dip trays and pipes, this way you are doing a full revision in keeping and maintaining your coffee maker clean.

Does Coffee Attract Ants?

Contrary to popular belief, there are no conclusive studies that can show that. Ants feel compelled and attracted to coffee residues, but on the other hand, coffee grounds are capable of disorientating ants.

Bonus: Ants can be highly attracted to sperm, this is the main reason why. 🤢😲😲😲

Do Coffee Grounds Attract Ants?

Coffee grounds do not attract ants, they are very susceptible to caffeine. When you leave coffee grounds in an ants path, they will carry it to the nest and eat it. But this will make them very confused and disorientated.

Chances are, ants will not follow that path again, at least for the next few weeks.

Can Drinking Coffee With Ants Make You Sick?
