10 Effective Ways to Get Rid of Ants in the Bathroom

We overlook it when we see one or two ants in our bathroom, but an ant infestation is not something that goes unnoticed. These tiny insects hover around our house in search of food, a moist and safe dark place to hide out. When they find the glimmering hint of favorable condition, they inform their colony, congregate and march towards it. 

After the kitchen, the bathroom ought to be their most preferred hideaway. Perfumes, bath salts, soaps, lotions, toothpaste, and water puddles are things that make our bathroom an ideal place for an ant infestation to thrive.

Fortunately, getting rid of these tiny friends isn’t difficult. With the help of several readily available products in your pantry, you can eliminate ants in your bathroom.

Are Ants Harmful?

Are ants harmful

“According to the National Wildlife Federation, there are more than 12,000 species of ants around the world. And the majority of these ants are harmless to people.”

All ants have the ability to bite. While their bites are rarely dangerous, certain of them, such as fire ants, sting and cause severe pain as well as allergies. Some of the most common types of ants in our bathrooms are

  • Pharaoh ants: They are often known as Sugar ants and are very common in your kitchen. They are often attracted to sugar, sweet taste, and fragrance. So if you have been using any fruit-scented products in your bathroom, that might be the reason for them to be there. To get rid of sugar ants from your house, minimize using fruit-scented products.
  • Carpenter ants: They prefer staying in places like decaying logs and damp places, and if you notice ants in the window, cracks, and broken tiles, chances are high they are carpenter ants. It is also possible that you have a satellite colony in your house, and they made their way through it. 
  • Argentine ants: Often, they are also called black ants, are some of the most common ants found in our home as they scavenge for food indoors. These types of ants, too, are found in our bathrooms. They are known to be harmless, though.

How to Get Rid of Ants in Bathroom

how to get rid of ant from your bathroom

You can use some household products such as vinegar, natural essential oil spray, and some other products to get rid of them. But before you start removing them, find out to exact cause and fix it. Then you can start the removal process as the chances of them returning back will be reduced once you stop the cause.

Boiling water

This might not be the exact way to get rid but pouring some hot water will definitely break their colonies. Pour the hot boiling water inside the hole where you notice them coming out and going in. When they spread around, you can kill them or can seal the ant holes. It will even be easy for you to kill them when they are not all together.

Spray vinegar and water mixture

In a spray bottle, mix vinegar and water in equal parts and spray in the ant holes or their colonies. Vinegar is acidic in nature and will kill the ants instantly. Ants cannot stand the smell of vinegar. The smell of vinegar will kill the ants even if it dries. So spraying vinegar is the best way to kill the ants in your bathroom instantly.


Combine half a teaspoon of borax, five teaspoons of sugar, and 1 cup of warm water to make a solution. Stir the sugar and borax until they are completely dissolved. Soak cotton balls in the mixture and place them near the ant swarm. Also, the places where they are seen most often. The sugar will attract ants, and when they eat the mixture, they will consume borax too. And the borax will kill them immediately. 

Essential oils

Cinnamon leaf essential oils, neem oil, lemon eucalyptus essential oil, peppermint oil, and tea oil are some of the common essentials oil that can be used to get rid of ants. Essential oils are produced from plants that are ants repellent and have strong scents that make following the pheromone trail difficult for ants.

You can either make a spray of this oil mixed with water or you can also soak the cotton in the oil and place it around the house in various areas where the ants are visible.

Diatomaceous earth

Diatomaceous Earth is a soft, siliceous sedimentary rock that can be crushed into a fine white powder and used to kill ants. It is both cheap and effective, but unlike other chemicals, it may take a while to show results. It will take 24 hours to kill ants if you sprinkle it on them.

The easiest way to kill ants using diatomaceous earth is to sprinkle it directly on them or the infested area when you observe them moving. If you’re dealing with indoor ants, line the ant trail and distribute the powder along with floors, window sills, wall crevices, and other small locations where ants are often seen.

Coffee grounds

Out of all other smells, ants cannot withstand coffee on top. Even better if the coffee is freshly brewed as it will kill them instantly. Coffee’s odor and acidity will repel ants. Sprinkle it in the area where they are most visible. The nitrogen burns the ants’ legs, so they won’t cross it.

As soon as they come in touch with the coffee, it will kill them. You can even make a mixture of coffee and sugar in a bowl and place them in your bathroom. Place around a spoon of coffee in a hole if you figure out the source.

Insecticides and Pesticide

Insecticides have long been seen to be the most effective and simple way to get rid of ants and are available in a variety of packages on the market. To get rid of the ants, you can either buy a liquid or a spray. Ants have an incredible sense of smell, and no matter what type of insecticides or pesticides you use, their strong smell will kill them instantly.

Liquid baits are based on boric acids, like Gourmet Liquid Ant Bait, and the best part is they will work way too fast compared to natural remedies. And it s recommended to use any kind of insecticides and pesticides following the precautions labeled on the back side of the package. 

Boric acid

Boric acid is a proven poison to ants. It will kill the ants as it directly affects their stomach and outer shell. Even the queen ants die immediately after consuming it. Stir together with a half tablespoon of boric acid, 5-8 teaspoons of sugar, and half a cup of water to make the solution. This solution can be poured into the ant hole, which is where the entire colony of ants lives. You can even soak cotton balls in the mixture and place them around your home in areas where ants are abundant. 

Caution: Keep the boric acid out of reach of the children and pets even while making the mixture, as it is hazardous to health.

Bait traps or bait gels

Most of the bait traps use boric acid or borax. At the same time, others use harsh chemicals called hydramethylnon, which is harmful as well but kills the ants immediately. When ants consume the bait, it will kill them. For some persons, bait traps with pesticides in an enclosed form may be preferred to sprays.

Verify the products before you buy as they include some harsh chemicals. Bait gels are another effective way to keep toilet ants at bay. To use these gels, insert the applicator tip into cracks and crevices and squeeze a little amount of bait gel into them. It will kill the ants when they come in contact with the gel.


There is a variety of aerosol foggers available on the market, so before you buy them, make sure the most important ingredient is available in it, which is cypermethrin. However, it will kill other pests such as spiders and can be harmful to your pets, so make sure you keep your pets away during fumigation. And it is best to do the fumigation if the ant infestation is excessive. And don’t forget to leave your washroom completely closed for up to two hours after treatment. 


Whichever above approach you use, your ant infestation must be eradicated. Try at least two or three approaches to get rid of a severe ant infestation. However, if you still have ants in your bathroom after trying several methods and identifying the source, it is better to get professional help. If you’ve had recurring ant infestations, it’s recommended to call an exterminator because the problem could be significant and difficult to deal with on your own.
