Features
  • Type: liquid bait
  • Usage: indoors
  • Active ingredient: Borax
  • Effectiveness: 2-3 days
  • Capacity: 6 oz

 More features: 2-pack, complete control may take up to two weeks, replacement every 3 months

This product is an excellent option for keeping ants out of the home. The main ingredient found in this product is borax; relatively safe for humans but deadly to ants. It comes in a clear form which makes it very easy to monitor. These features and more make it our undoubted top choice from all the others on the market.

Using bait stations, this ant killer effectively traps ants and is so easy to use. It helps to get rid of the ants that you see traversing the floors of your home.

This liquid option is made to eliminate ants over 3 days. Due to its active ingredient, the bait doesn’t immediately start to act. This is great because it allows enough time for all the ants to return to their colony before it strikes. Furthermore, when ants come in contact with it, they take it back to their colony, spreading it among the other ants.

These will also come to the bait and get the toxic ingredients. This cycle continues until all the ants in the colony are ‘infected’.

Interestingly, it has been made not to dry out quickly. Hence, the ants have a steady supply of ‘food’ until they are all dead.

Another reason why we love this product is the ease of use. All you need to do is to break up each station and cut along its colored markers. Once that is done, you can place the bait where the ants frequently pass.

As it comes with up to six stations, you can set this up around several places in the home to increase the effectiveness.

Pros
  • Kills effectively
  • Can be used for months on end
  • Doesn’t quickly dry up
  • Effective at killing several insects over time
  • Safe to use
Cons
  • Not safe for kids

  • Effectiveness: not specified
  • Capacity: 10 lbs

 More features: 100% organic, wide range of applications, produced in the USA

If you are looking for a high value option, then look no further than this product. It is a 100% natural ant killer. Therefore, it is safe and can be used around your children and pets. Furthermore, unlike some other options on the market, it is impossible for ants to grow immunity to it.

The diatomaceous earth is a substance that looks just like white talcum powder. In simple terms, this substance is a type of sand made from just fossilized remains of diatoms. It is so effective against ants and other types of insects.

To use this product, sprinkle it in any locations that are frequented by ants. This product can be used in all types of places, ranging from the cracks in the wall to outdoors and so on. In fact, this product is so effective that it is used as a barrier to prevent not just ants, but other types of insects from entering the home.

For the best results, use this product in dry areas of the home.

It should be noted that when you want to apply it, you should always wear a face mask. This is because although it isn’t toxic, it can cause some eye irritations when the powder enters the eyes.

Pros
  • Excellent value for money
  • Friendly on the environment
  • Zero-fragrance
  • Can be used outdoors
Cons
  • Not effective for ant colonies
  • Slow action
  • Can cause eye irritations

  • Capacity: 12 oz

 More features: 2-pack, 2-step method, kills the queen and up to 162 mounds, no watering-in required, money back warranty

It might be our budget pick, but the low price doesn’t make this product any less effective. This product is an excellent blend of safety and impressive potency. It comes with the ability to show effective results in just a few hours. It doesn’t smell horrible like some others on the market.

If you have a fire ant infestation, then no other product works quite as well as the Ortho Orthene. Fire ants are known to be stubborn insects that are quite difficult to get rid of. However, this product will effectively get rid of them and other insects in your home or environment.

It comes in a form that can easily permeate the soil to reach the main ant colony. Application is quite straightforward. All you need to do is to sprinkle it on the ant nest or mould. After a short period, it is absorbed into the nest, reaches the queen ant, and solves all your ant problems. It has the active ingredient acephate, which acts by breaking down the ant’s nervous system.

To achieve the best results, we recommend that you apply this product in seasons where ants are very active.

The product will remain in the soil for up to half a year, which is truly impressive. Since it lasts for so long, ants are repelled and are unable to build a new mound or install a new queen.

A 12 ounce killer, you can use this product to get rid of up to 162 ant mounds.

Pros
  • Highly effective in killing insects
  • Kills quickly
  • Remains active after 6 months of application
Cons
  • Horrible smell
4.

Syngenta - TRTD11568 Best Gel Ant Killer

Features
  • Type: gel
  • Usage: outdoors/indoors
  • Active ingredient: Thiamethoxam, .010%
  • Effectiveness: not specified
  • Capacity: 05 oz

 More features: effective against argentine ants, carpenter ants, and ghost ants and other nuisance ant pests, palatable for at least 14 days, non-staining and colorless formulation, ready-to-use package

If the ants are coming in via cracks and crevices in the home, then a gel ant killer is what you need. It is highly effective against different types of ants. It comes with all that you need to reach the cracks in the home. Hence ants that are sneaking in will be repelled or will die in the process of entry.

Some of the types of ants that you can get rid of using this product include ghost ants, harvester ants, fire ants, carpenter ants, and so on.

It comes with a quartet of tubes that contain the el. Additionally, there is a plunger. This plunger helps you to reach hard-to-reach spots in the area and stop the ants from coming in.

It comes in food form for the ants. Hence, they eat it and take it back to the colony and the queen ant. It is poisonous to the ants as it has Thiamethoxam as the main ingredient.

One issue I had while using this product is that it dries over time; which is quite surprising as it is a gel product. Furthermore, it is not very effective in the rain.

Pros
  • Attractive to ants
  • Powerful active ingredient
  • Plunger comes in very handy
Cons
  • The gel dries rather quickly
  • Less effective in the rainy season
Features
  • Type: spray
  • Usage: outdoors/indoors
  • Active ingredient: Sodium Lauryl Sulfate, Oils
  • Effectiveness: instant
  • Capacity: 16 oz

 More features: wide range of applications, 100% organic, money back guarantee

This product is one of the safest options to use today. It employs organic, natural ingredients to drive out the ants from your house. Although all the ingredients are safe (which is great if you have kids and pets), it acts really quickly and will last for a long time. Additionally, apart from getting rid of the ants in the home, it also acts to repel those that have not yet come in.

This product is made with different ingredients, all of which contribute to make a top-notch product that effectively gets rid of ants in the home or environment. It is made with sodium lauryl sulfate, spearmint, rosemary, and peppermint.

Aside from the ingredients above, it also contains vinegar. Vinegar is useful because it erases the scent trail of the ant. That way, the ants cannot follow each other to food sources which will eventually lead to starvation.

The peppermint found in the product is quite toxic to ants. Fire ants are some of the most persistent species of ants you can find, and when applied in high concentrations, this oil can chase them away.

It should be noted that this particular product isn’t going to get rid of the entire colony. However, it acts as a repellant that ants will surely want to avoid.

Overall, it is an excellent product that works not just by killing any ants in the vicinity, but it also prevents them from coming back to your home. From our testing, it is one of the best outdoor ant killers on the market today.

Pros
  • Kills invading ants
  • 100% natural and safe for children and pets
  • Long lasting effect
  • Fast acting
Cons
  • Somewhat expensive

Taurus SCBest Liquid Ant Killer

Features
  • Type: liquid
  • Usage: outdoors
  • Active ingredient: Fipronil
  • Effectiveness: 1-3 days
  • Capacity: 20 oz

 More features: non-repellent insecticide

This is the best liquid ant killer on the market. It is highly effective against ants and other types of insects. Due to its excellent versatility, it can get rid of different infestations and issues. It comes with a concentrated formula that ensures that just a little application can go a long way in getting rid of all the ants in your home.

Taurus SC is great for eliminating all types of insects, but it is especially effective in getting rid of ants. It is not only good for getting rid of infestations, but it also serves as an excellent barrier protector. Hence, it will keep out insects ranging from ants to spiders and beetles.

Taurus SC is quite easy to use; as long as you follow the instructions. Before applying it, you need to do some preparation. It is available in 20 oz. and 78 oz. bottles. According to the manufacturer, you should use just 8 ounces for a gallon of water. This measurement is easy to get since the bottle is designed to measure the amount dispensed automatically.

The main ingredient in this product is fipronil. Fipronil is a potent ingredient that is often found in insecticides and used in controlling insect populations.

This product is one of the most potent options on this list. Therefore, when you apply it, you should be careful not to let it affect other useful insects like bees.

When used appropriately, this product is quite safe.

While many products on this list are fast-acting, Taurus SC is slow acting. This allows enough time for ‘infected’ ants to come in contact with other ants, thus increasing the effectiveness of the killer and eliminating the breeding colony.

Pros
  • Concentrated formula is very effective
  • Targets the entire colony
  • Useful against different types of insects
Cons
  • Relatively expensive
  • Highly toxic

With this product, all you need to do is point and spray. It kills instantly and serves as a barrier; preventing ants from coming into the home.

We like it because it doesn’t leave a heavy smell in the air after application. It also will not induce coughing.

This spray does not eliminate the colony or get rid of the queen ant. However, if you have a small infestation and need to get rid of it fast, then it makes for an excellent deterrent.

Pros

  • Kills on contact
Cons
  • Only for small infestations

Buying Guide

In the section above, we considered 8 of the top products that you can find on the market right now. Before making the list, we considered several parameters. In this section, we will highlight and discuss these parameters. We will also provide other useful information that can help you as you make a buying choice.

What is an ant colony?

Several times in the reviews above, we talked about the effectiveness of the product with regards to an ant colony. Well, what is an ant colony?

An ant colony, in simple terms, refers to the nest or home built by ants. It is where they live and store food. It can also refer to their social organization.

The ant colony isn’t just the mould that you see. The anthill is just the top of the colony, like the tip of an iceberg. While anthills might rise as high as a person, they go even deeper underground. In fact, some of these colonies can have tunnels that are as deep as 25 feet underground.

The colony is controlled by the queen ant. She lays the eggs and is responsible for the propagation of the ants.

In one ant colony, you can find tens of thousands of ants! Some of these ants can even form ‘supercolonies’ that can contain millions of ants!

If you have a new colony in your backyard, it might not contain as many ants and can be easily handled.
8 Best Ant Killers - Problem Solved

How Can You Prevent Ant Infestations?

  • To prevent an ant infestation, you must take several proactive steps. The first thing you must do, is to ensure that your home is clean. This is doubly important for your kitchen and other areas where your food is stored.
  • The floors of the home should be clean and free from food and drink spills.
  • You must also ensure that your garbage is regularly removed.
  • If you have pets, keep their food on elevated surfaces and enclosed to prevent attracting ants.
  • You can also seal up any cracks or crevices in your home as these can be entry points for the ants.

Types of Ant Killers

There are 4 main types of ant killers on the market today. These are bait, gels, powder and spray. Each of these types comes with different features and accomplishes different results.

Let’s consider each of these types.

Spray

Sprays are used to kill the ants on contact. This type of treatment is designed for broad application and is very effective on different types of insects and not just ants.

Sprays are very effective, especially over a long period. Some of the options on the market, for example, the Raid Ant and Roach Killer can last for several months after application.

Another feature that makes spray treatments appealing to folks is that they are quite cheap.

Sprays are easy to apply if you know where to apply it.

One main disadvantage of spray treatments is that the colony is not effectively eliminated using spray ant killers. They do not kill the queen.

Bait

This treatment is quite different from spray treatment. It is highly effective in getting rid of a colony. They are made to be taken back to the colony and often have delayed killing action. Bait, unlike spray treatments, are not effective over extended periods. If you apply it outdoors, the elements can interfere with the effectiveness.

Bait, as the name implies, comes in food form. It attracts a large number of ants in the area and slowly gets rid of the ant population.

8 Best Ant Killers - Problem Solved

The main reason why folks prefer them to spray treatment is that they can actually get into the colony and eliminate the queen ant, as our Editor’s Choice TERRO T300B 2-Pack Liquid Ant Bait Ant Killer does.

Powder

This type of ant killer also comes like bait, since the ants have to be attracted to it before it can work. They are quite effective and can be a long-term solution.

You can leave them at a designated spot in the home or outdoors for months on end. As soon as the ant eats the powder, it often ends up dead. An example of this is the DiatomaceousEarth DE10. 

Gel

An example of a gel ant killer is the Syngenta – TRTD11568. This treatment usually comes in a small quantity and is applied to smaller areas in the house. It is especially effective when placed in crevices and cracks in the home.

The ingredients in the gel do not kill the ants immediately.
Instead, the ants carry the gel to the colony, spreading it, and ensuring that the colony doesn’t come to your home anymore.

Which should you choose: Spray, Bait, Gel or Powder?

Well, it is hard to say which one to choose because there are different parameters that can affect the effectiveness. Some of the parameters that you should consider in this regard include the type of ant, the moisture and humidity, the environment, and so on.

Features to consider

Before making a final buying choice, there are different features that you need to consider.

Ease of use

You don’t want to buy a product that you will find rather difficult to apply. Your ant problem needs to be tackled head-on and promptly. Therefore, you need to choose an option that can be easily applied.

The ease of use depends on where the ants usually come from.

Spray ant killers are excellent since they can be used over a large area in one go. If you crave instant action, then you will likely love using this option.

However, if your infestation is in a small area of the house, then you might opt for other options.

Consider the actions that will be required in applying the ant killer to ensure maximum effectiveness.

Natural or Chemical-based

Many of the ant killers on the market seek the easy way out and use chemicals to get rid of the ants around you. These chemicals are admittedly highly effective. They usually act really quickly. However, they come with several drawbacks.

Since they are made from chemicals, they can be dangerous to the health of humans and pets. Before opting for a chemical-based product, consider who might become exposed to it.

Natural options might not be as quick-acting, but they are effective and safe to use. They are child and pet safe. The EcoRaider Ant Killer is one such natural option.

Regardless of the type of ant killer you choose, ensure that you closely adhere to the manufacturer’s instructions before using it.

Longevity

One issue with ants is that once gone doesn’t mean always gone. They can always come back. If you discover that these insects always infest your home, then the best option is to choose an ant killer that will last for months on end. In this case, you might want to choose a powder or bait ant killer.

Price

Before you choose an ant killer, you should be sure that the price it offers matches the value. You don’t want to spend plenty of money on a product and discover that it isn’t as effective as you would have wished.

FAQ

Yes. However, for maximum effectiveness, you need to use a type of ant killer that can permeate the hill and kill off the queen. You need to first identify where the colony is. Once this is done, the next step is to use ant baits. Bait ant killers are highly effective because they use the ants way of life to destroy them.

Once the ants eat the bait, they carry some of it back to the colony and share it with other ants. The bait is slow-acting, so it reaches as many ants as possible. If the ant dies in the nest, it is eaten by other ants, which also ingest the poison.

Yes, they are. Many of the main ingredients found in these ant killers are also quite toxic to other types of insects. Hence, if you have an insect population that you want to protect (for example, a beehive), you have to be careful with application.

Our Verdict

There are so many options available on the market today. We recommend the TERRO T300B 2-Pack Liquid Ant Bait Ant Killer as our top choice. The main ingredient found in this product is borax; relatively safe for humans but deadly to ants. It comes in a clear form which makes it very easy to monitor. Our value pick is the DiatomaceousEarth DE10. It is safe and can be used around your children and pets.

Furthermore, unlike some other options on the market, it is impossible for ants to grow immunity to it. Lastly, for folks on a budget, the Ortho Orthene Fire Ant Killer1 is a good option. This product is an excellent blend of safety and impressive potency. It comes with the ability to show effective results in just a few hours. It doesn’t smell horrible like some others on the market.

We hope that you use this guide and review to select the best ant killer right now.
