Why are there ants in my shower?

Ants could be in your bathroom sink for a variety of reasons.

However, one of the most typical explanations is that they are searching for food. And because of the abundance of supplies, ants are attracted to bathrooms and kitchens.

Furthermore, they may be drawn to wetness, so they might infiltrate your shower, sink, or drains.

There could be a variety of additional food sources in the shower that attract ants, for instance:

  • Other pests such as dead flies, flying termites, bathroom roaches, and recluse spiders
  • Shampoo/body wash that is organic or homemade
  • Food or other edible waste in the trash bin in your bathroom
  • soiled clothes
  • There may be dirt or other edible materials in your bathtub or shower.
  • Garbage accumulated in your shower drain (dead skin, fungus or mold, fermented hair, etc.)
  • The smell of the shower drain
  • The odor of mold or mildew
  • Sludge in your pipes

Another reason ants may infiltrate your home is to find a suitable location to establish their nests. Ants prefer warm, humid environments to make their nests, so if you have those elements in your home, you may be more likely to have an ant infestation.

Finally, ants may also invade your home and eventually bathrooms, searching for a warm location to hide from the cold. Ants dislike excessive cold or heat; thus, they frequently seek shelter in dwellings during the winter when they can no longer survive outside.

Types of Ants That Like Your Shower

There are a variety of ants that can be found in your bathroom, but black carpenter ants are one of the most common. This type of ant is attracted to moisture and is often found near leaks in your shower.

Black carpenter ants like to build their nests in moist and dark environments like your shower. Unfortunately, they can cause problems by constructing their nests in wood, which might result in damage.

Pharaoh Ants are another ant species that might be found in your shower. Pharaoh Ants are little, around 1/16 inch long, and yellow or light brown in color. These Ants, unfortunately, are also attracted to wetness, making them tough to eradicate.

The Argentine Ant is another sort of ant you can find in your shower. These ants are small and dark brown or black in color. Ants of this species prefer to reside in big colonies and can be hostile.

People and animals have been reported to be bitten and stung by this ant, though the bites are usually not dangerous.

What are they attracted to?

There are a few things that ants are particularly drawn to, and that can attract them to your bathroom sink.

One of these is food residue or garbage. If there is any sort of food debris, ants will be more likely to invade. Additionally, ants are attracted to moisture, so leaving water spots or dripping taps can also lure them in.

Ants are also attracted to chemical attractants: this means that they can be drawn to scents and odors, which can lead them into the shower or drain. As such, it is important to take care of what you put down in the sink and avoid leaving any food or garbage around.

Finally, if your bathroom has any cracks or openings where ants can sneak in, they will also take advantage of that.

How are the ants invading your bathroom?

If you see ants in your bathroom, it is important to determine how they are getting in and address the issue.

The ants invading your bathroom sink are likely coming from cracks and crevices in the home’s infrastructure. These critters can find their way in through tiny openings and start building their nests inside.

However, other regions that stimulate ant invasion in your bathroom include the sink, toilet, or drain.

Furthermore, the ants could also invade your bathroom through a window. If it’s hot and humid outside, the ants will be hunting for a cool spot. Make sure to close all of the windows and doors in your house to prevent them from entering.

Locate and Seal Ants’ Entry Point

In order to eradicate ants in the bathroom sink, it is important to locate and seal their entry point. Ants can enter through any tiny crevice or hole in the house, but they are especially attracted to the bathroom area because of the moisture.

Try checking around pipes, windows, doors, and any other openings in your bathroom—then use caulk or silicone sealant to close off any potential entrances.

Keep our Bathroom Dry

If you have a bathtub, you must keep the wood behind it dry at all times.

When a leak occurs, such as in the bathtub, the water enters the wood and causes a spill. The wood studs become moist as the water seeps through, producing a filthy environment. Ants are drawn to situations like this, and they will find a way to get through.

The warmth of the shower will also entice them. Don’t leave it unattended, or the water may flow all over the floor.

After bathing, ensure to clean up. Allow time for the shower to dry before entering the bathroom.

To summarise, close the cracks and make sure the shower is completely dry to get rid of these pesky animals.


The process of eliminating moisture from the air is known as dehumidification. 

Dehumidifying the environment is one of the greatest techniques to get rid of ants in your bathroom sink. Ants thrive in moist environments, so keeping your bathroom clean and free of moisture will help deter them.

You can use a dehumidifier to achieve this or take other measures such as fixing any leaks in the bathroom and using an exhaust fan when showering.

Use of Insecticides

There are a variety of ways to get rid of ants, and insecticides are one of the most effective.

Insecticides can be bought over the counter or online and typically come in the form of a spray, liquid, or powder. These products can be sprayed onto corners and moist areas where ants are likely to congregate.

However, measures must be taken, such as fully washing your hands after using them and keeping them away from youngsters.

Ant Baits

There are numerous ant baits available on the market. All of them work by enticing ants and encouraging them to forage for food. The bait is usually some type of sugar or protein.

The success of using baits to get rid of ants in the bathroom sink is due to the social structure of ants. Worker ants bring food back to their nest, where they feed the queen and male ants. This way, the poison from the bait travels throughout the entire ant colony, killing all of them.

Natural Ant Spray

The natural ant spray is effective when sprayed in areas where the ants are congregating. For example, spraying it on floor corners and other dump areas surrounding the bathroom should get rid of them.

When using a natural ant spray, be sure to clean the area thoroughly after spraying. Ants will likely move around as they attempt to relocate their colony.

Keeping the Home Clean

Regular cleaning, such as cleaning surfaces where ants can be attracted, such as around and around the bathroom sink, is one technique to help keep ants out of the house.

In addition, keeping food sealed and garbage disposed of properly will help discourage ants from entering the home in search of sustenance.

Furthermore, It is also important that proper sanitation be maintained in order to avoid such sewerage leaks.

Contact an exterminator

Although it is possible to get rid of ants in the bathroom sink on your own, it is important to ensure they are eliminated completely. If you do not take care of the problem, the ants will come back, and you will have to deal with them again.

Therefore, in case you are having trouble getting rid of ants in your bathroom sink, it is best to contact an exterminator. They will be able to help identify the source of the problem and provide a solution.

Eliminating Ants in the Bathroom Drain with Natural Remedies

Lemon spray

One easy way to get rid of ants in your bathroom sink is to make a natural ant killer using lemon juice. Simply mix lemon juice with water and spray it around the areas where you see ants.

Diatomaceous earth

Diatomaceous earth is a natural product that dehydrates ants, killing them. It can be sprinkled around the areas where you have seen ants or on their trails.

When using diatomaceous earth to get rid of ants in the bathroom sink, keeping it out of direct contact with water is important. It will lose its efficacy if it gets wet, and the ants will likely return.

Furthermore, While DE can be effective, it can also take some time to work depending on the amount you use and the size of the ant colony.

Remember When using diatomaceous earth to exterminate ants, extreme caution is required. Avoid inhaling it and getting it on your skin using masks and gloves.

Baking soda and vinegar

Baking soda with vinegar is one of the simplest and most efficient ways to get rid of ants. First, pour a lot of baking soda down the drain. Following that, add white vinegar to the baking soda.

The two substances will react with one another, resulting in a fizzing sound. Allow this reaction to work for around 15 minutes before flushing the drain with hot water to remove any dead ants or muck that has accumulated.

Essential oils

Ants are a common problem and can be eliminated using essential oils. The most effective essential oils to use against ants are peppermint, lemongrass, lemon, lavender, cedar, and eucalyptus.

These oils repel the ants and keep them from coming back. You may either apply the oil directly to the ants or mix it with water and spray it all over your bathroom.

Furthermore, Diluting the oil before spraying it will make it less strong smelling and more effective against the ants.


Another effective way to get rid of ants in your bathroom sink is to vacuum them up. Suck these critters up with a powerful vacuum cleaner and get rid of them for good.

When vacuuming an area where you’ve seen ants, make sure to empty the tank or canister immediately after; this will avoid releasing live ants and prolonging the infestation.

Boric acid

Boric acid is a white crystalline powder used to kill ants. It’s available in most pharmacies and supermarket stores. When ants are exposed to boric acid, their digestive systems are destroyed, and they eventually die.

While Boric acid can effectively get rid of ants, it should only be used in specific areas. It is best to use boric acid around the edges of your bathtub, shower, or toilet, where water may wash it away.

However, it is important to avoid contact with or consumption of boric acid, as it can be harmful if ingested.

How to get rid of carpenter ants in the shower?

Many of the measures listed above should be sufficient to help control and reduce the number of carpenter ants in your shower.

Using vinegar and baking soda, lemon juice spray, and borax, you may destroy them. Then add spices, aromatic oils, or DE to permanently eliminate them.

Maintain a steady pace and don’t let up until they’re gone. Ants breed quickly, so if you want to get rid of them, you’ll need to get rid of the entire nest.

Other ants

You can employ the same methods with other ants, such as little black or brown ants, pharaoh ants, or other species. There isn’t much of a distinction because they all work against them in the same way.

Again, the key is to experiment with each to determine which one works best for you.

How to get rid of Ants permanently?

Ants are difficult to completely remove unless the nest is destroyed. You must locate the nest, which can be found in a variety of locations:

  • Floorboards in your bathroom
  • the void within your wall
  • Crawl spaces in bathroom cabinets
  • Bathrooms in the attic or basement
  • Behind baseboards or tiles
  • Crevices or cracks
  • Shower doors

Even if you can’t identify the nest, the methods in this article can help you minimize their numbers. However, finding the nest is the only method to permanently exterminate them.

If you don’t have time to do it yourself, or if you’ve tried everything and still haven’t gotten results, Consider hiring a qualified expert.


Ants are a common problem in the household, particularly if they invade your bathrooms. However, there are several methods to get rid of them.

Some people choose to use chemical-based solutions, while others rely on natural methods. No matter which method you choose, it is important to be consistent with your treatment and to follow the instructions carefully.
