10 Steps to Stop Argentine Ants Invading Your Home

How to Stop Argentine Ants from Invading Your Home

Ants are some of the most resilient and resourceful creatures on the planet. They have been around for millions of years and can be found in virtually every corner of the world, from the deserts of Africa to the rainforests of South America.

Among them, the Argentine ant is one of the most invasive species. They have rapidly spread to countries around the world, occupying gardens, homes, and businesses.

They are difficult to get rid of once they invade your home. However, there is a solution.

The following steps will provide you with everything you need to know about identifying Argentine ants, their behavior, where they live, what they eat, how to get rid of them, and how to prevent them from coming back. What Are Argentine Ants?

The Argentine ant is an invasive species that originates from South America. They are small, about 2.2-2.8mm long, and light to dark brown in color.

Their most distinctive physical feature is their antennae, which are long and segmented. Argentine ants have multiple queens within their colonies, which is why they can grow very quickly in numbers.

The Argentine ant is rather harmless, but they can contaminate food and other surfaces as they scavenge for resources. Where Do They Live?

Argentine ants have rapidly spread across the globe and are now found in many countries. They tend to thrive in warm, wet climates, so they are most commonly found in places like California, Hawaii, Japan, and Australia, but they can still adapt to many other environments.

How Long do They Live? The lifespan of Argentine ants is relatively short, with worker ants living up to a few months, and queens up to a few years.

A colony typically has about 80% workers.

Life Cycle

Argentine ant colonies usually consist of multiple queens, making them incredibly tough to control. Queens lay hundreds of eggs.

After around 2-3 weeks, eggs hatch into larvae, which grow and develop as their food source is provided by the worker ants. The larvae eventually mature into adults that function as workers, queens, or males, depending on their role in the colony.

What Do They Eat? Argentine ants are omnivores and feed on a variety of things, including sweet, plant-based foods, oily foods, proteins, and honeydew produced by aphids.

Once colonies have found a reliable food source (or multiple sources), they will persistently return to the same place over and over again.

Argentine Ant Size

The most visible members of an Argentine ant colony are the workers and queens. Queens can be up to twice the size of workers.

How to Get Rid of Argentine Ants Step-by-Step Instructions:

Identify the Root of the Problem

The first step to controlling Argentine ants is to identify the source of the problem. Check your property for any sources of food or water that may be attracting the ants.

This includes food left out on counters, spilt liquids or crumbs on the floor, and overflowing garbage cans. Once you identify the source, make sure to seal it off if possible.

Wipe Down All Surfaces in Your Home and Take out the Garbage

Before taking further action to eliminate Argentine ants, wipe down all surfaces with a vinegar solution to remove any chemical trail that the ants may have left behind to guide them back to their food source.

Taking out the garbage regularly and using tight sealing bins will help to prevent any leftover food from building up a scent trail.

To avoid encouraging ants to enter your home, keep countertops clean and free of food debris.

Set up Ant Baits

The go-to solution to control Argentine ants is to set up ant baits. These are poison traps that attract ants to feed.

Once they consume the tainted food in these traps, they will carry it back to their colony, feeding it to the rest of the ants. This way, you can deal with an entire colony through a single trap.

Homemade ant bait can be made with boric acid, a substance that works to kill ants efficiently. Mix boric acid with a tempting sweet liquid (such as honey or sugar syrup), and place the mixture in a container with several entry points for ants.

Make sure to label the container and place it far from children and pets. DIY Ant Bait | Argentine Ants Boric Acid

One of the most popular homemade ant baits involves a mixture of boric acid and sugar.

Mix one tablespoon of boric acid, one tablespoon of sugar, and one tablespoon of warm water until the boric acid dissolves. Dab the mixture onto small pieces of cardboard and place them near ant trails.

How to Get Rid of Argentine Ants Naturally

If you are looking for a more natural approach to get rid of Argentine ants, try sprinkling cinnamon, mint, dish soap, baby powder, chalk, or diatomaceous earth around the home’s entry points to repel the ants.

Cinnamon and other powders work to repel the ants and disrupt their scent trails.

Mint and essential oils offer a similar benefit since these smells are also unpleasant to ants. Dish soap can kill ants on the spot and make it difficult for them to walk on surfaces.

Baby powder can act as a deterrent too, but many others suggest diatomaceous earth as it works mechanically to kill the ants.


Argentine ants are a tricky ant species to manage. However, identifying the root of the problem, maintaining a clean home, and using effective solutions, such as ant baits or natural remedies, can help you control your Argentine ant infestation.

Regularly monitoring the effectiveness of your approach will help you keep your home protected. By following these instructions, you should be able to live a happy and Argentine ant-free life.

Argentine Ant Bite Treatment: What to Do If You Get Bit by an Argentine Ant

Argentine ants are a small but mighty species, so if you’ve found yourself on the receiving end of an Argentine ant bite, you might be wondering what to do and how to treat it. Although Argentine ants are non-aggressive and usually don’t bite people unless they feel threatened, the bites can still be painful, itchy, and irritating.

In very rare cases, ant bites can lead to infections or severe allergic reactions, so it’s essential to know how to treat Argentine ant bites properly.

Argentine Ant Facts

Before we delve into the topic of how to treat ant bites, let’s take a brief refresher on Argentine ant behavior. Argentine ants are an invasive species that have spread across the world, and it is common to find multiple colonies interacting as a massive supercolony.

They have a high queen-to-worker ratio, which allows them to reproduce and grow rapidly. Argentine ants leave a pheromone trail to help guide other ants to a food source, and these trails can lead them into homes.

If you have ever encountered Argentine ants, you may be familiar with the pungent odor they emit. This odor is used to identify and communicate with other ants, and it can be quite strong when there are many ants present.

Argentine ants are non-aggressive and do not pose any significant threat to people or pets. They are more of a nuisance as they scavenge for food, and they can contaminate surfaces.

However, if they feel their colony is in danger, they may bite as a defense mechanism.

Argentine Ant Bite Treatment

Argentine ant bites are generally not considered harmful, but you can still feel a bit of discomfort, itching, and pain. The first step in treating an ant bite is to wash the area thoroughly with soap and water.

This will help to remove any dirt or bacteria from the bite site and reduce the risk of infection. If the ant bite is causing discomfort or itching, you can apply a cold compress or ice pack to the area.

This will help to reduce the swelling and ease any pain or itching sensation. An over-the-counter antihistamine cream or ointment is also useful at reducing itching, burning, and inflammation.

If you notice any signs of an infection, such as pus, redness, discharge, or fever, you should seek medical attention immediately. Any bites on the face or neck, or if the bite victim has a history of severe allergic reactions, requires medical treatment as soon as possible.

Allergic Reactions

While rare, some people may experience an allergic reaction to Argentine ant bites. Symptoms may include severe itching, hives, swelling, difficulty breathing, dizziness, and even anaphylaxis, which is a severe, life-threatening allergic reaction that requires immediate medical attention.

If you are experiencing severe symptoms, call 911 or get to the nearest emergency room or urgent care clinic right away. Antihistamines, adrenaline shots, and steroids are among the options a medical professional might choose as an instant treatment for severe allergic reactions.


Although Argentine ants are not aggressive and usually do not pose a severe threat to humans, some people might experience a rare allergic reaction to their bites. If you are bitten by an Argentine ant, wash the area promptly, apply a cold compress, and if necessary, take an over-the-counter antihistamine cream for itching and other functions.

People with severe allergies should take extra care to avoid Argentine ants. If anyone experiences an allergic reaction to an ant bite, seek immediate medical attention.

In conclusion, understanding Argentine ants is the key to keeping them from invading your home. Identifying the root of the problem, wiping down all surfaces, and setting up ant baits are the most effective ways to get rid of them.

Additionally, natural remedies like cinnamon, dish soap, and baby powder can also be used to repel Argentine ants. While they may not be harmful, Argentine ant bites can cause discomfort and irritation.

It’s essential to take the necessary steps for prompt treatment, wash the bitten area, apply a cold compress, and seek medical attention for severe allergic reactions. Understanding Argentine ants’ behavior, as well as their potential danger, is vital for successful control and prevention.

By following these steps, you can have a healthier and pest-free living space.
