Ants are one of the most frustrating, yet harmless pests you can get in your home, and getting them in your home is a regular occurrence, unfortunately. Especially when the weather starts to get warm! I used to get a long line of ants through my front door and into my cat’s food bowl. That was until I replaced the front door! Now they cannot get in at all. Once they get into your kitchen, ants can get anywhere, including your dishwasher, which brings me onto the point of this post: How to get rid of ants in your dishwasher… let’s take a look!

Where Are Ants In My Dishwasher?

Before we can look at how to get rid of ants in your dishwasher, we need to have a look at why they are getting in there. What is driving them to get into your dishwasher?

Whilst it is not very common to get ants in your dishwasher, it doesn’t mean that it cannot happen. Ants are pretty easy insects to understand, and once you understand what their primary objectives are, you can understand why they get pretty much anywhere!

Here are the 5 most common reasons they get into your dishwasher…


Access to Water

Ants need water, and your dishwasher will offer them exactly what they are looking for. There will be collections of water in the dishwasher, along with potential leaks in the pipework of the dishwasher.

These collections of water will attract ants to it.


Access to Food

It is not just collections of water that will sit inside your dishwasher. As you put your plates and cutlery inside the dishwasher, you are also adding small pieces of food.

Also – your dishwasher is likely to have a mesh protecting your drain from food that you may have left on the items you have added to the dishwasher. This mesh will collect remnants of food until you clear it out. This is a huge attraction to ants!


Route to Food

If you notice ants coming in through your dishwasher then it could be because your dishwasher is in the way of the food supply. Luckily (for the ants) your dishwasher is relatively easy to traverse.

If this is what is driving ants to your dishwasher it should be fairly obvious because they will simply be marching in a line through your dishwasher.

Ants lay down a chemical trail to let other ants know that they have found some food. This is why you will notice a line of them.


Nearby Nest

I got ants in my dishwasher once, and it was because there was an ants nest under the kitchen window! The nest was being hidden by some patio slabs which is why I didn’t see it until I had an infestation.

Needless to say, the nest was directly the other side of the dishwasher (there were bricks in the way) however, there were entry points in the brickwork (my bad). Which brings me onto the final reason:


Entry Points

The only reason you have got ants in your house (and therefore your dishwasher) is due to you having at least one entry point.

Ants only need a very, very small gap to gain entry to your home. They will also only need a small hole to get into your dishwasher. If you look behind the dishwasher, you will find tons of entry points, especially around the water inlet and outlet.

1. Check Entry Points

There are various entry points that ants can use to get into your dishwasher. Your first job is to find them, and deal with them!

Sure, it is a challenge to cover up many of the entry points, especially around the back of the unit where the cover is not great. However, you should check around the unit for entry points that are easy to cover up.


2. Lemon

Lemon is excellent for ant control! In fact, it is a top natural way to kill ants in your dishwasher.

Simply load up a water spray bottle with lemon juice and water and spray onto the ants, and over any areas where you have noticed ant activity.

I’ve not tested it, but it might also be worth using lemon scented dishwasher tablets. Even if they do not work get get rid of ants, at least your dishes will smell good.


3. Vinegar and Water

Similar to lemon, vinegar is a very strong natural ant killer and repellent. Not only is it good to clean them up with, but it is also very good for destroying the chemical trail used to let other ants know there is a food supply nearby.

Mix up 5/50 water and white vinegar into a spray bottle, and spray anywhere you have seen ants. Be sure to unplug the dishwasher first.


4. Boiling Water

Although the water gets very hot in your dishwasher, it may not reach to areas where you notice ant activity. You should pull the dishwasher out and pour it on them if you can.

Be careful not to pour water onto the electrical parts of the dishwasher, and always unplug it when dealing with the ant problem by using any liquid.


5. Borax

There are two awesome ways that you can use this! 1. Sprinkle borax in the dishwasher for ants to walk on (and under the dishwasher). 2. Make some borax balls for the ants to feast on!

Always store borax away from children and pets. Once you have scattered the powder or applied the borax balls in the area infested by ants, make sure to keep kids and pets away from those too!
