Why are ants present on my toothbrush?

There are many reasons behind the presence of ants and some other insects like cockroaches in your toothbrush. 

Toothpaste chemicals

Many people do not rinse the toothbrush carefully after cleaning their teeth. As a result, the toothpaste on the brush’s bristles attracts ants toward the brush present in the box.

The chemicals present inside the toothpaste produce a strong smell that helps them locate their food. In addition, the chemicals present in the paste can fill their empty stomach.

Moreover, it contains sodium lauryl sulfate, sorbitol, and fluoride that can attract these insects, and it is at risk of ant infestation.

Food remains 

You can use a toothbrush to remove the food particles from your teeth. However, these particles can damage your teeth if you do not remove them for a long time.

These food particles can stick to the bristles when you brush your teeth.

They can detect the presence of food in every corner of the house, so there is no chance that they ignore the food in it.

They use a pheromone signal to identify the exact food location and follow each other to reach there.

Many of these insects can reach there by following the scent trails when one gets access to the food.


These insects need water to live in dry conditions, so they keep searching for moisture in the house. When you put a cover on a wet toothbrush, the moisture gets locked inside it.

Moisture can attract a swarm of ants towards it and provide them with water droplets to fulfill their water requirements.

Sweet odor 

They can recognize the sweet odor of toothpaste by smelling it from far. These insects can detect a strong smell and locate even tiny pieces of food.

So, they can reach the brush, which gives off a sweet odor due to the presence of toothpaste. It contains sweet sugary chemicals like sorbitol that attract them.

How to get rid of ants from my toothbrush?

After washing, dry it completely before adding a cover to it. It is better to air dry it before packing to evaporate the moisture.

Clean the sink 

The sink can also attract insects because it remains wet most of the time, and it can accumulate near the sinkhole to get moisture.

Sometimes, it falls on the sink corner by mistake, attracting these insects.

So, it is better to clean the wet sink with a clean cloth and dry its surface. In addition, remove all the drops of soap and toothpaste from it.

Proper storage 

When you keep brushes in an open area like close to the bathroom sink tap, there are many chances of insects attacking it.

This is because you provide a clear surface to these attacks for an attack.

You have to put it in a closed cupboard after use. The cabinet can protect it from their infestation and keep your brush safe from germs.

Cover the brushes

Some manufacturers provide caps for covering the bristles from germs attacks.

At the same time, some brushes are without caps, so you have to put them correctly in plastic bags after use.

Moreover, you can get thick plastic covers to keep them safe from their attacks. These covers act as a barrier and prevent their entry inside.

Keep toothbrush vertically

They can quickly attack the toothbrush, which is present horizontally on the sink or over the box. These insects can trail and reach the bristles and damage your brush.

It is better to keep it straight or vertically so these tiny organisms cannot easily reach the bristles. These preventions can help you in getting rid of these insects.

Are ants attracted to toothpaste? 

Toothpaste can attract ants by producing a strong smell due to the presence of chemicals or sweetening agents inside it.

Sorbitol is present in some kinds of toothpaste, sugar, or carbohydrate. This ingredient is almost 58 to 62% sweet in taste and can attract these insects efficiently.

In addition, sodium saccharin is also present in these pastes, a sweetening agent. The sugar can cause tooth decay, but the sodium saccharide does not damage your teeth.

Furthermore, it contains xylitol, which can protect your teeth but can attract insects due to its sweet odor.

Why are ants attracted to mouthwash? 

Mouthwash can attract ants due to its chemical composition, which contains many flavoring agents that give a sweet odor.

They remain on the bottleneck of mouthwash because most of these contain alcohol. The percentage of alcohol varies from 20 to 25% in different products.

Chlorhexidine gluconate is present in the mouthwash, a medicated product that kills bacteria effectively.

Moreover, this gluconate chemical in these products attracts insects towards it when they are locating for the food.

Therefore, this chemical has the potential to attract these insects, but they do not like the taste after eating it.

Similarly, Listerine mouthwashes can also grab the attention of these insects, and you can see the colonies around the neck area of the bottle.

Will toothpaste kill ants? 

Some kinds of toothpaste are effective ant repellants because they contain baking soda, cinnamon, and peppermint. They avoid the strong smell of these ingredients and remain far away.

The peppermint is not only effective against them, but it can also keep other insects like mosquitoes away from you. These insects do not like the strong smell of peppermint.

In addition, cinnamon is good at killing ants because they can die due to suffocation when they consume it.

Furthermore, a combination of baking soda with any one of these ingredients in toothpaste can keep the insects away from your house.
