Fortunately, there are several common home remedies for you to know how to get rid of ants that are quite effective.
But before we dive into home remedies for ants, it’s important to first identify how they got in, and where they are located in your home.

Things to Do Before Using Home Remedies
Whether it’s a seasonal or year-round issue, finding ants inside your home can be extremely frustrating. In most cases, ants enter your home looking for food or water. If they find a food source, they will keep coming back until it is gone.
The situation can get much worse, however, when ants decide to build nests indoors and become your newest roommates.
If you have ants inside your home, you may notice that most congregate around food and moisture sources or in areas they feel protected, like under appliances or floors. That’s because ants eat a lot of the same things humans eat, including sugars, starches, and even some meat.
In most cases, the ants are after the crumb or two left behind on your cutting board or stove. That’s why it’s so important to keep your home clean if you want to eliminate indoor ants.
So, before utilizing any natural remedies for ant removal, you should first do the following:
- Identify the species of ant – Because not all ants behave the same way, correctly identifying the ant is one of the most important pieces of information you can have in treating the infestation.
- Find the trail and follow it – Ants don’t enter your home through the front door like other house guests. They enter through cracks and gaps in your foundation, windows, doors and walls. Finding the trail of ants will help you determine where they are coming in, so you can look for holes and cracks. Seal up anywhere wires or pipes enter your home. Once you find the trail, you’ll know where to set traps and bait.
- Eliminate excess moisture – All living things need water, and ants are no different. Eliminate as much moisture as possible from the kitchen and bathroom by fixing leaks or cleaning spills. This deter ants from coming inside.
- Regularly mop your floors – Dirty floors are breeding grounds for ants. Regularly sweep up crumbs and mop the floor to get rid of any residual sugars or food that could attract an army of ants.
- Keep everything clean – After a long day of work and cooking dinner, it’s easy to leave the sink full of dirty dishes. However, these dirty dishes are prime targets for many species of ants. Along with cleaning dishes right away, regularly clean the dishwasher, microwave, and oven. Don’t forget to take out the trash, too. You should also make sure to keep leftovers and other food products in a sealed container in the refrigerator. Apply these cleaning techniques to outdoor eating and grilling areas as well as anywhere else you may eat or drink.
- Vacuum – Carpet can trap a lot of crumbs and other materials, so make sure to vacuum on a regular basis. If the infestation is bad, you should vacuum daily. Keep in mind that vacuuming can also suck up some of the ants that are invading your home. Just be sure to empty the canister and the trash after vacuuming. Otherwise, the ants will just crawl right out of the can and back into your home.
- Don’t forget the outside of your home – To go in and out of your home, ants need a safe environment to return to after finding food and water. Move items such as mulch, fallen logs, tree limbs, or anything else that provides protection or moisture to ants away from your home’s foundation. You should also trim all tree limbs to make sure they aren’t overlapping or touching your home. Additionally, do not store firewood inside your home unless it has been thoroughly inspected for ants.
By being proactive about cleaning your home, you can control the factors that brought ants into your home in the first place. After eliminating the source of the ants, you can then take appropriate action to eliminate them and ensure they never come inside again.
Before we start talking about natural ant remedies, let’s talk more about ant identification. Knowing what type of ant you’re dealing with will help you find the right solution to get rid of them. After all, different ant species have different behaviors, habits and diets.
Here’s how to identify some of the most common house ants:
- Pavement Ants: About 1/8″ in size and dark brown or black in color. They nest under rocks or pavement, and they have many queens. They’re all one size, and they do have a stinger. They love sweet and greasy foods.
- Carpenter Ants: About 5/8″ in size and black or red in color. They burrow into wood to create their nests. They’re large in size, and love sweets (including honeydew from aphids).
- Odorous House Ants: About 1/16”-1/8″ in size and brown or black in color. They have many queens and many homes. They also love sweets, especially honeydew.
- Acrobat Ants: About 2.5-3 mm in length. These ants vary in color, from brown to red-black, yellow-brown and all black. These ants are aggressive and will sting.
10 Natural Home Remedies for Ant Removal
After doing everything possible to eliminate the ants’ source of food and moisture in and surrounding your home, it’s time to start killing them. Home remedies will allow you to get rid of ants and do so with products that are in most people’s homes.
Hardware stores are full of ant poison, but applying poison inside the home isn’t always ideal, especially if you have small children or pets. Fortunately, there are a number of natural remedies that are equally as effective as poisons.
1. Lemon Juice
While it doesn’t kill the ants in their tracks, lemon will act as a natural repellent and keep ants away. That’s because the acidity and smell of lemon affect an ant’s ability to smell and find its original path.
Whenever ants enter a home and find a food source, they leave behind a trail of pheromones. These chemicals let other ants know that there’s food ahead. But lemon juice interferes with the ant’s ability to pick up on the scent trail. If applied in the right places, ants won’t know how to get back in, or how to find the trail.
The citrus smell should also deter them from making a new scent trail.
How to Apply:
Put lemon juice in a spray bottle and spray the entry points to your home. Apply this solution daily to any spot that you’ve seen ants entering and exiting your home.
You can also soak cotton balls in lemon juice, and place them near entry points and other areas where you see ant activity.
For this remedy, you can use freshly-squeezed lemon juice, or the bottled lemon juice you find in the grocery store. The bottled variety is more convenient, and you won’t have to waste fresh lemons on those pesky ants.
It’s hard to imagine anyone not liking cinnamon, but it’s an effective way of keeping ants out of your home for good. Just sprinkle some ground cinnamon or spray cinnamon oil around doors, window sills, floors, and anywhere else the ants are coming in.
You can also mix cinnamon with cloves for an even more effective treatment method. Not only is it an effective way of deterring ants, but it’s easy to clean up and leaves your home smelling great!
How to apply:
Simply take a cup of water and add ¼ to ½ of a teaspoon of cinnamon essential oil to it. You can soak a rag or a cotton ball in this natural home remedy for ants and apply it to any surface where you have seen ants in your home. Continue to use this solution on a daily basis until you no longer see ants inside.
If you want to use fresh cinnamon, simply sprinkle the spice along entry points, windows and doorways. You can also put the powder inside holes, cracks or gaps that ants may be coming in through.
3. Borax and Sugar Mixture
While the above treatments work mostly to keep ants away, this solution is an actual ant-killer. You can find borax at your local hardware or grocery store, or online. This solution is attractive to ants and is extremely toxic to them. It can be used in the home or your garden to significant effect.
The sugar will attract the ants, and the borax will kill them. But the borax works slowly enough for ants to take the solution back to the nest and share with their nest-mates. After a few days or a week, you’ll wipe out the entire nest, including the queen.
Borax has a low toxicity to humans and animals, but when ants eat it, it interferes with their digestive system.
How to apply:
Simply mix borax in a bowl with sugar and just enough water to make a paste. Put the paste in ants’ path or set it out on a countertop. You can do this directly on the ground or spread it across a piece of wood or cardboard.
Worker ants will take the mixture back to the queen, which will kill her and any other ant that eats it. This method is useful, but does require some patience and may take weeks to see results.
Read the detailed instruction on how to kill ants using borax.
Warning: Of all the home remedies for ants listed on this page, this mixture is the most dangerous to children and pets. Make sure not to leave any mixture containing borax out where kids or pets can come into contact with it. Click here to read our review of pet safe ant killer
4. Powdered Sugar and Baking Soda
Similar to the borax mixture, this combination will slowly kill the ants over time. Ant species that are attracted to sugar will ingest it with the baking soda.
Ants have a naturally-occurring acidic substance in their bodies that will react with the baking soda and will die. This home remedy ant-killer is extremely effective because the ants will often carry this food source back to the colony to be consumed by the queen and other ants.
How to Apply:
Mix baking soda, powdered sugar and just enough water to make a paste. Apply the paste to cardboard or paper, and place it near the ants’ entry points in your home.
Be diligent and re-apply the bait as needed until the entire nest is wiped out.
5. Coffee Grounds
The good thing about this remedy is it is readily available in most homes across the United States, and it’s a great way to use your old, used grounds after making coffee in the morning.
Coffee grounds act as an ant repellent. It won’t actually kill the ants, but it will keep them away. They especially don’t like the smell of grounds from freshly brewed coffee. The ants will walk right up to the coffee, turn around, and walk the other way.
This ant remedy is great for people who don’t want to necessarily kill these pests. A repellent will allow ants to continue doing their jobs outside, but leave you in peace in your home.
How to Apply:
Let the coffee grounds dry out and place them in cracks where you see the ants entering your home. You can also spread the grounds in your garden, other areas of your yard, and even around the perimeter of your home.
You’ll need to re-apply the grounds every few days or after it rains.
Make sure that you keep pets away from the coffee grounds. Most dogs and cats aren’t fond of the smell, but we all know that pets can be curious creatures. Coffee grounds can cause caffeine poisoning in dogs and cats, so keep them away from treated areas.
6. Boiling Water and Soap
These two ultra-common household ingredients can be used to demolish any ant mound in your yard. If you know the location of the nest or mound, merely apply this mixture and instantly kill the ants inside.
It’s a gruesome remedy, but it will work. The combination of boiling hot water and soap will both drown and “cook” the ants. The key most important thing is to make sure that the solution reaches the queen. Otherwise, you may need to re-apply it a few times until all of the ants are dead.
How to Apply:
Boil a pot of water and add dish soap to it. Remove the pot from the stove (using an oven-mitt) and take the water outside to the mound.
Carefully pour the water and soap mixture directly onto the hill, making sure not to splash yourself and scald yourself in the process. This is a simple-yet-effective way to kill the ants in your yard immediately.
7. Diatomaceous Earth
If you haven’t tried diatomaceous earth (DE) for your ant problem, you need to start. It’s all-natural, easy to find, inexpensive and really effective.
What you may not know is that DE is actually the fossilized remains of algae-like organisms known as diatoms. Their skeletons, known as silica, are mined from lakes, rivers, oceans and streams.
DE is completely harmless to mammals, but it’s deadly to insects with exoskeletons. You can’t see it with the naked eye, but DE particles are very sharp. Their sharp edges stick to the ants and become lodged in between their joints. With each move the ant makes, the DE particles shred apart its exoskeleton.
It sounds gory, and it is, but it also works. DE may also stick to ants and soak up moisture, causing them to dehydrate and die.
DE is safe to use around humans and pets. You can even eat food-grade versions of the powder.
How to Apply:
Sprinkle DE wherever you see ant activity. Place it along ant trails and entry points. Place it outside in the garden. You can put it anywhere where ants may get to it.
If you use DE outside, make sure that you re-apply the powder after it rains. The rain will wash away the powder, rendering it useless.
Most DE products come with a handy dusting tool, and you can usually buy several pounds at a time.
Ants, like many other insects, hate the smell of peppermint. Peppermint’s strong scent works much like lemon juice – it masks the scent trails that other ants leave behind.
This remedy won’t kill the ants, but it will keep them away from your home.
How to Apply
There are a few different ways to use peppermint to control ants. The simplest method is to create a mixture of water and peppermint essential oil. Just add about 10 drops to a regular spray bottle filled with water. Spray the solution along windows, doors, cracks and other areas where you see ant activity.
If you really want to eliminate the scent trails, spray along the trail, and wipe away the solution. When you wipe away the peppermint oil, you’ll also be wiping away the chemicals that attract ants. Just be sure to re-apply the solution to keep them from coming back.
If you don’t want to spray the peppermint, you can always soak cotton balls in a peppermint/water solution and place them where there’s ant activity.
Both of these options will keep ants away and leave your home smelling fresh.
If you want to stop ants before they even get inside, you can plant mint along the perimeter of your home. The mint plant will keep many types of insects away, including mosquitoes and spiders. Just keep in mind that mint spreads very easily – like weeds. Once you plant it, you’ll have a hard time getting rid of it.
Vinegar is a powerful cleaner and insect repellent. It can also help eliminate ant trails. Because it’s safe and natural, you can use vinegar to clean counters, floors and other hard surfaces.
Yes, your home will smell like vinegar, but the smell won’t last long. It’s worth the inconvenience to keep ants away.
Nests that are visible can also be soaked with vinegar to remedy the problem.
If you don’t necessarily want to kill the ants but want to evict them from your home, repellents are a fast and easy way to make the ants leave.
Chalk is an old ant remedy that your grandmother and great-grandmother probably used. Ants don’t like walking through this powdery substance.
Simply draw a line of chalk along entry points, like window sills and doorways. You can use old-fashioned school board chalk, or you can buy the powder sold in home improvement stores. The kind sold in stores comes in a squeeze bottle that makes it easy to apply.
11. DIY Ant-Away Spray
Feeling ambitious and want to get rid of your ants with a little ingenuity? We have the perfect mixture of essential oils that will send ants running for the hills.
Simply place the following in a spray bottle:
- 15 drops of tea tree and peppermint oil
- 7 drops of citrus oil
- 1/4 cup of water
You can also add vodka into the mixture. If you choose to go without the vodka, you will need to shake up the bottle often.
The only thing that is left to do is spray everywhere ants have been. Spray entry points and even their colony if you know where it is located.
What Ants Eat
Ants are after two things: food and water. These two life essentials are what most insects and animals will be drawn to when migrating and finding a new place to live. And if you’re noticing that ants are starting to overrun your home, it means they have found a food source, or there is a food source nearby.
Water is a must-have for ants, so they’ll gravitate to any source of water that is available.
When it comes to what ants actually eat, this can be broken down into two categories:
What Ants Eat Outdoors
It may not seem like it right now, but the majority of ants live outdoors and not in your home. When outdoors, ants eat a variety of different foods. In fact, they probably have a more diverse diet than you.
Ants will eat:
- Sugars and Fruit: Ants love sugar. Sweet foods are the weakness of ants, and they will look for sugar in a variety of different areas. Fruits, plants and flowers will be eaten by ants. Nectar and sweet liquids left from aphids, called honeydew, are also a major part of the ant’s diet.
- Seeds and Grains: Certain types of ants, harvester ants in particular, will try and harvest plant seeds for food. These ants will also eat other plant material, such as grass and leaves. Grains are also harvested by the harvester ant.
- Meats and Protein: Some ants prefer to eat meat and protein. Ants have been known to feast on fish, dead rodents and even large animals. Army ants have been seen killing larger animals before devouring them. Insects are also a part of some ants’ diets. Yes, cannibalism is common in the ant world.
- Vegetables: Another part of a well-rounded diet, ants will chow down on vegetables, too. The majority of ants will flock to vegetables, which is why they often are present in gardens. They may not eat your asparagus, but they will eat plant leaves and may even eat the food from crop-bearing plants.
These are just some of the foods that ants eat. Believe it or not, ants have evolved greatly and some of their actions show just how smart they can be.
Herding ants are especially smart and actually make a pact with aphids. An aphid is an insect, like a caterpillar, which will leave a sweet secretion behind called honeydew. Ants love sweets, and honeydew is at the top of their list of foods. Herding ants will devour the honeydew and in turn, they will protect the insects that are producing the honeydew.
This mutual agreement allows ants to have an endless amount of food to eat.
Interestingly, aphids are often forced into this relationship. Ants will eat the wings of some aphids, forcing them to stay nearby – a cruel act.
Science Daily also released an article in 2007 that provided proof that ants have chemicals on their feet that will tranquilize entire aphid colonies to keep them close and provide food for the colony.
Some ants, leaf cutter ants in particular, use the leaves of plants to create a fungus, which they will eat.
In the wild, ants have a near-endless supply of food sources. In most cases, there is little you can do to limit the outdoor food sources of ants.
Before we talk about what ants eat indoors, I want to take a minute to talk about carpenter ants. Most people make false assumptions about their diets. Let’s clear the air.
Carpenter Ants Don’t Eat Wood
Contrary to popular belief, carpenter ants don’t actually eat wood. These ants are not termites, but they can be problematic nonetheless. Carpenter ants will burrow into the wood of your home, which can cause structural damage.
They won’t actually eat the wood – they’ll just burrow through it.
What Ants Eat Indoors
The most important food that ants eat (as far as you’re concerned) is the food that they eat indoors. If you know what these foods are, you can eliminate them from your home so that the ants have less of a reason to stick around.
If there is no food to eat, the ants will go elsewhere.
We already know that ants love sweet substances. This means that they’ll flock to:
If you have kids, you know that they aren’t the best at keeping food where it belongs. Something as simple as leaving fruit on a plate in the bedroom or a piece of candy left under a bed is enough to attract a small army of ants.
A few of the other foods in your home that ants will flock to include:
- Jams and jellies
Ants may even flock to a loosened jar of jam because there is remanence of the substance left behind on the jar itself.
Virtually any food that may have been dropped or that is left out in the open will be a target for ants. We’ll be discussing a few of the things you can do in your home to eliminate some of the things that attract ants.
If you want to get rid of ants at home, in the kitchen, in the office or the bathroom, it’s important to find and eliminate their indoor food source. We’re going to show you how, and we’ll also share other ways to get rid of ants for good.
6 Simple Ways to Keep Ants Away from Your House
Get rid of the food or water source, and you’ll starve the ants out.
If you have ants in your home, there is a near 100% chance that the ants are coming over for dinner. This means that you need to do a thorough cleaning to get rid of them. A few ways to protect your home from ants are:
1. Clean Daily
Each time you drop a crumb of food, you’re leaving a small feast for ants. Even a tiny piece of sugar stuck in the fibers of the carpet is enough to attract ants. So, your only action is to clean – a lot. I recommend creating a cleaning schedule that will allow you to keep your home spotless and ant-free.
A cleaning schedule may be:
- Vacuuming the floor daily (Sunday – Sunday)
- Cleaning bathroom counters every other day
- Cleaning kitchen counters daily
- Mopping kitchen floors daily
It sounds like a lot to do, and it is a lot of work. But if you clean daily, ants will have less of a reason to keep coming back to your home.
2. Eat at the Table Only
I get it: sometimes, you want to eat on the couch. The couch is more comfortable. You can flip through television channels, or watch your favorite show or sports while chowing down.
Everyone likes to indulge and relax.
But when you eat on the couch or on the floor, there is also a much higher chance that you’ll drop food on the floor. A crumb here and there is all it takes for ants to see your floor as a buffet.
Making it a rule to eat at the table only can help prevent this problem. If you have children, this is also a good practice.
Young children drop food or spill drinks on the floor. That’s the nature of being a kid. Your little one may not want to get in trouble, so they do their best to hide these messes from you. Before you know it, that juice they spilled on the carpet behind the couch has become a buffet for ants.
Other children are forgetful and may leave leftover cookies in the closet or on a nightstand, allowing ants to come in and eat away.
Let eating be a time for you and the family to spend time together and discuss your day.
Incorporating an eat-only-at-the-table rule will allow you to quickly be able to clean up messes, and it will reduce a lot of the chores mentioned earlier. Plus, you’ll only have to vacuum or mop a limited space – it’s fantastic.
3. Fill in Holes and Gaps
Holes and gaps around your home make it easier for ants to get inside. While ants have a way of entering even the smallest of spaces, you can do your best to reduce the chances of ants invading.
A few of the most prominent places to look for gaps or holes are:
- Doors: The doors of your home will have gaps. These small gaps can be closed with proper trim, and you can also use draft guards for larger gaps. Look for gaps at your front door as well as any other doors entering the home.
- Baseboard: Gaps between the baseboard and the wall allow ants to traverse your home with greater ease. Block off these “roads” with a little caulking or by replacing the baseboard. When done properly, this will keep all types of bugs from poking their head out and skittering across the floor.
- Windows: Small gaps near windows are also places for entering the home. If you can feel a draft from a window, this is likely enough space for an ant to enter. Seal off outside and inside holes or window gaps.
If you seal off the entryways into the house, you’ll be better protected against ants. Keep in mind that you’ll likely overlook some spots where ants are entering the home.
4. Remove Overlapping Branches
An often-overlooked way to keep ants away is to remove overlapped branches near the home. Branches often overlap at the roof, which will allow ants to trail into the home. Remove and trim these branches as necessary to make it harder for ants to enter your space.
5. Fix Any Moisture Issues
The best ant killer is removing all water and food from the home. And one area which you’ll want to pay special attention to is moisture. Small leaks will supply enough water for ants to drink, and even leaking pipes that you may not see can be the culprit.
Older basements where water may be entering can be an issue, too.
I’m not recommending outfitting your home with all new pipes, but do try to fix any leaks or drips. If you find water anywhere in the home and suspect that there may be an internal leak, contact a certified plumber to track down the leak and correct the problem.
If you allow water to leak, you’ll create a far bigger problem than having ants.
6. Throw Garbage Out Quickly
Garbage bags are an ant’s paradise. The smell of garbage will attract ants. When the scouting ants come, they’ll leave a scent behind that all of the other ants will follow to come and chow down on your garbage.
If you leave your garbage out, ants will find it and leave a scent so that the rest of the colony can use the scent to find the food.
When there is a major ant problem, try and throw out your garbage quickly. Change out big garbage bags and get rid of the trash daily if needed.
If you have a habit of leaving the garbage outside your front or back door, this needs to end. Not only will ants come crawling over, but bees, rodents, roaches and other insects will begin to invade your yard and make their way into your home.
The Damage Ants Can Cause to Your Home
Ants inside your home can cause a lot of damage. They cause structural damage, and their bites or stings can cause physical harm to you and your family.
Carpenter ants burrow inside wood to build their nests. They don’t actually eat the wood (that’s what termites do), but they can still cause structural damage if the infestation gets out of control.
Fire ants can cause physical harm, especially to young children. They swarm and sting relentlessly if you disturb their mound. Kids who are playing in the yard may not realize they’re near a fire ant mound.
Some people are allergic to ant stings and fire ant bites. In this case, an onslaught of fire ant bites can lead to a trip to the emergency room.
As a property owner, it can be daunting to think about fighting off an insect that outnumbers humans one million to one. Fortunately, there are many natural ways you can take action to eliminate ants from your home, yard, and garden, and most of the remedies can be found in your pantry and under your sink.
Benefits of Using Homemade Remedies
If you are a homeowner who is struggling with an ant infestation in your home, rest assured that you are not alone. Fortunately, there are many solutions for eradicating these insects from your home, lawn, or garden. While expensive and sometimes harmful pesticides and poisons are effective, they may not be the best solution for you.
For homeowners who are looking for an inexpensive and natural remedy for ant removal, there are many options (like the ones listed above). The benefits of using baking soda, cinnamon, coffee grounds, lemon juice, and other common household substances are clear. You can:
- Create homemade ant-repellant or ant-killer without spending a lot of money on expensive pesticides
- Can quickly address the ant-infestation problem without having to go to the store
- Use all-natural ingredients that are not harmful to the environment
- Keep your kids and pets safe from accidental ingestion of a toxic substance (please note: the remedy that suggests using borax could be harmful to children and pets)
Some of the best and most effective remedies for killing ants can be found in your own kitchen. By following the steps listed above, you can effectively kill them or at least disrupt their path into your house.
But it’s not enough just to kill the nest or keep the ants away. You need to take steps after treatment to keep the ants from coming back to your home. Prevention is always the best solution.
What to Do After Applying Ant Remedies at Home
Once your home remedies have effectively killed the ants in your home, it is time to make sure that they do not return. There are a few practices that you should adopt that will hopefully prevent the pesky insects from returning. These best-practices include:
- Routinely clean your kitchen and workspaces with lemon juice or vinegar to make sure that ants do not return to those areas. These acidic solutions will eliminate the ant scent trails that led these pests into your home in the first place.
- Do not leave pet food out overnight. Instead, store pet food in the refrigerator or a sealed container overnight to keep ants from getting to it. Protein or fat-loving ants love pet food, and it’s a very convenient, easy food source for them to gather. Remove the food, and the ants will have no reason to come back.
- Clean up spills immediately, and don’t leave sticky or sweet substances on floors, tables, or countertops. Ants are attracted to sweet products like soda, jams, honey, and other food, so make sure to clean up spills thoroughly.
- Inspect your home regularly for cracks, worn weather-stripping, and windows and doors that are not aligned properly. Ants can fit through tiny spaces, so any visible holes or entry points should be repaired immediately. Caulk, which can be found in most home improvement stores, can easily fill and seal cracks that may be giving ants access to your home. Several of the home remedies listed above are incredibly useful for repelling ants, so be sure to apply these mixtures as needed.
Ultimately, the goal is to make your home as uninviting as possible for ants. By keeping surfaces clean and applying the home remedies for ants listed above, you at least have a fighting chance against these all-too-common invaders.
Once ants get into a home, there is practically no chance that they’ll choose to go away on their own. It will be up to you to figure out a natural solution for removing them. Hopefully, by using some common household ingredients, you can safely remove the ants in your home and keep them from ever coming back.
If you try and fail to no avail, you may need to hire an exterminator to take care of your ant problem.
