11 Simple Ideas to Kill Ants in the Bathroom (2022)

If the ants in your bathroom are part of an ant infestation, you might be looking at a colony of thousands of ants. Besides being a nuisance, these pests can transport bacteria, and an ant problem in the bathroom could even indicate moisture damage. To know how to get rid of ants in the bathroom, it’s essential to understand what attracted them there in the first place.

Ants come in your house in search of food and shelter because they like moisture and the smells coming from your bathroom pipes. They view fermenting human hair as a tasty food source and freestanding water as drinking water.

If you’re dealing with sugar ants in the bathroom, you may be wondering which specific ant species is causing you problems. It is likely one of several species of ants, but likely candidates include carpenter ants, pharaoh ants, Argentine ants, and odorous house ants.

How to Get Rid of Ants in the Bathroom

Why are tiny ants in my house? Why are they in the bathroom of all places? At certain times of the year, there’s a small chance that you’ll see a swarm of flying ants inside your house.

The ants are scaring you by coming out of hiding to mate, but, thankfully, it’s easy to distinguish them from the more destructive termites. Ants have a pinched waist, longer front wings, and bent antennae (..).

Before you fork over money to an exterminator, we have simple and effective home remedies for ants in the bathroom. With our safe DIY ant control tips, you’ll get rid of tiny black ants in the bathroom in no time.

Clean and Caulk Your Bathroom to Prevent an Ant Infestation

Proper sanitation is the best way to get rid of ants in the house. Keeping your bathroom clean and dry ensures that little black ants do not see it as a paradise of food and water.

Clear that hair from the drain, mop up puddles regularly, and give your trash can a good wash. Ant colonies love to nest in crevices, so, once you’ve eliminated the entire colony, caulk all possible entry points and hiding places.

If you can’t figure out where the sugar ants in the bathroom are coming from, leave out some food, such as diluted honey, and wait for one of the critters to carry it back to the ants nest.

How to Get Rid of Ants in Drains

Pour baking soda and then vinegar in equal quantities down the drain where ants have made their home. Keep bathroom doors and windows open to allow for proper ventilation.

After the mixture has finished bubbling up, remove the dead ants and flush away the remaining baking soda with hot water.

You can also carefully pour boiling water from a kettle down the drain. These are two quick but effective ways to kill ants in the bathroom naturally.

Ant Baits for Sugar Ants

Attract sweet-toothed ants with their favorite foods laced with Borax, so that they will carry this ant killer back to their colony. Be cautious with this recipe if you have pets or small children.

Fill a straw by repeatedly dipping its end into a mixture of these three ingredients. Cut the straw into 1/2-inch pieces and lay the pieces along ant trails.

You can also combine one part Borax with three parts powdered sugar or three parts warm maple syrup. Place these baits in small containers, such as bottle caps, around your bathroom.

Some ants like protein, while others prefer sugar, and adults can only eat liquids, while larvae will eat solid food, so target different types of ants by using a variety of baits.

Set Ant Traps in Your Bathroom

Kill ants right on the spot using ant traps. Some ants will probably even bring the trap’s contents back to their colony.


Sugar and Borax Ant Trap

  • 1 cup granulated sugar
  • ½ cup of water
  • 1 tbsp Borax

In an old plastic container, dissolve the sugar in water, then stir in Borax. Poke holes in the lid so that ants will be able to reach the sweet yet deadly substance, and tempt them further by sprinkling extra sugar around the trap.

Easy Natural Ant Repellent Spray

You can also go another route and use a repellent. This DIY natural ant killer spray works wonders for driving off those tiny black ants in the bathroom.


Homemade Vinegar Ant Spray

  • 1 cup distilled white vinegar
  • ½ cup of water
  • 2 tbsp dish soap
  • 5 drops of lemon oil
  • 5 drops of peppermint oil

Shake the ingredients in a spray bottle then squirt the mixture onto any possible ant entry points, reapplying once a day. Take comfort in using a natural form of pest control.

You can also make a homemade bathroom cleaner with this spray. Use it on countertops and tubs, as well as the sink, floor, and toilet.

Use Essential Oils to Repel Tiny Black Ants around Your Bathroom

Send ants running using essential oils such as peppermint or tea tree oil. Make a natural ant repellent spray out of ten drops of essential oil and one cup of water. Tea tree oil has such a strong scent that it kills any ants that dare to enter your bathroom, particularly if you add a dash of cayenne pepper.

Alternatively, pour a little essential oil onto cotton balls and place these wherever you have found tiny black ants in the bathroom. Whichever method you choose, essential oils are a great bet if you’re wondering how to get rid of ants in the bathroom quickly and safely.

Have you ever asked yourself, ” Why are there gnats in my bathroom?” Sometimes these annoying flying insects come up through the drain. This ant repellent works just as well to eliminate your ant problem, too.

Spice Up Ants’ Lives

Ants aren’t fans of spices, particularly cayenne pepper, cinnamon, and salt. Sprinkle these powders along windowsills and doorways and in corners – wherever ants might be entering your bathroom. Or, mix a little cinnamon into some water to make a spray.

We love this straightforward way to convince ants to leave your bathroom alone. It’s also quite an effective home remedy for carpenter ants that have made their way inside the house. However, be wary about using cayenne pepper around children or pets.

How to Get Rid of Ants in the Bathroom using Citrus Fruit

We love the versatility of citrus fruit, such as lemons and oranges, for repelling ants. Place leftover peels or pour some juice on any cracks, crevices, and entryways. Just remember to replace the peels or juice every couple of days.

You can also use lemon juice to clean your bathroom floor in a ratio of the juice of four lemons for every half gallon of water. Besides driving off ants, this solution will leave your bathroom smelling clean and fresh.

Confuse Ants using Flour or Chalk

Sometimes, people ask the question, do ants eat flour? The answer is yes, so you could use flour as an ant bait, although we recommend using it to disrupt their trails.

You may have noticed that ants tend to follow the same paths. This phenomenon occurs because ants deposit chemicals known as pheromones, which ensure that all members of a colony can find their way back to the nest.

You can disorient the little black ants in the bathroom by pouring flour or chalk powder onto their standard routes.

Kill Ants using Diatomaceous Earth

Use Diatomaceous Earth (DE) to kill several types of insects, including ants, by drying out their bodies. Be sure to use the food-grade variety, which is safe around pets and children, and which you can find at many home, garden, and pet stores.

For most species of ants, sprinkle the DE along their trails and at entry points. For carpenter ants – large black ants that make smooth holes in wood – get DE as close to their nest as possible.

Either inject the white powder into cracks using a medicine dropper or make a spray out of two tablespoons of DE and one quart of water. DE is an important option for a carpenter ant infestation because this species does not carry food back to its nest.

Sprinkle Baby Powder to Repel Ants

Have you wondered what to do with that container of baby powder at the back of your cupboard? You may have heard that baby powder has many uses, but did you know that you can use it to chase off ants?

Sprinkle this powder on ants’ trails and entry points to regain control of your bathroom. Be confident knowing that your children and pets will be safe when you use this method to get rid of sugar ants in the bathroom.

How to Use Borax and Boric Acid to Get Rid of Tiny Black Ants in the Bathroom

As we noted, you can make ant bait by combining Borax with either powdered sugar, maple syrup, or peanut butter and granulated sugar, or create an ant trap out of Borax, granulated sugar, and water. You can find this versatile product at businesses like hardware stores and grocery stores.

Use other pest control solutions if you have pets or small children because Borax can cause skin irritation and is toxic if consumed. You can also spread boric acid powder, available at big-box stores, on cracks and entryways.

Keep in mind that boric acid is dangerous for pets and children and that it will only work against Argentine ants, pharaoh ants, and odorous house ants.

Borax Ant Killer for Pet Owners

Combine these three ingredients and pour the mixture onto cotton balls. Place the balls near ant trails, so that the pests will carry the insecticide back to their nest.
