What Are the Best Indoor & Outdoor Ant Killer Types?

If you’re experiencing a continuous ants-in-the-house issue, chances are you haven’t yet discovered the best indoor ant killer product for you. You may have tried some DIY ant eliminating recipes, along with the proven ant prevention tactics.

However, preventing pests from getting into your home is one thing, while defeating them once and for all is another issue. Let’s dwell upon the main categories of ant killing solutions and their characteristic features.

Ant Bait Stations

Your ant invaders prefer hiding behind the walls, in between the window panes or beneath the floor. Because these areas are uneasy to access, seeing where exactly your tiny enemies enter your home from is rather challenging. In this case, using insecticide liquid baits is an excellent solution. Generally speaking, ant baits are perfect ant killers for both inside and outside use. They are created to target the household ant species.

After the ants dine on the liquid bait, the product’s active component gradually influences their digestive system. Later, when they carry the bait to their dwellings feeding it to the queen and their friends, the whole colony gets eliminated. Ant baits are a hassle-free ant killing solution. Baits are initially packaged with the poison and powerful food attractant combined in a plastic child-proof container.


If you’re interested in solving occasional ant invasion problems, ant aerosol sprays are an excellent option. Sprays work perfectly well when it comes to destroying the ants you can see. Sprays are a quick fix since they do not destroy the ants’ nests. In the majority of cases, spraying ants will keep your property pest-free for up to one month.

Sprays have two disadvantages though. First, their effect is short-term. Second, most sprays contain hazardous chemicals, so always use them in a properly ventilated room and keep them away from kids and animals.

Ant Gels

Typically, these products come in convenient tubes with a syringe. You can utilize them directly in the areas where your tiny enemies enter your home on a regular basis. Additionally, you can use gels on the ants’ tracks outside your house.

These gels are excellent ant killers for indoor and outdoor use. They are not toxic and safe to use near kids and pets. The most powerful gel traps feature slow acting poison accompanied by a very strong food attractant. Ants carry the gel back to their mound where it eventually eliminates the whole nest.

Granular Ant Bait

This type of ant bait is one of the best indoor and outdoor ant killer options. It targets their source and finally destroys all their nests. Advance, one of our experts’ favorite solutions, features Abamectin which is a natural environment-friendly fungus – something that ants simply cannot resist.

After consuming the granular bait, the ants take it back to their colony where it eliminates the whole nest within just a few days.

Is your home attacked by a specific type of ants? Using a product that targets this particular ant species is the best option. For example, Advance ant baits were created to eliminate carpenter ants, although they also work pretty well on other ant types like Pharaoh ants and Argentine ants.

If you’re fighting with carpenter ants, go outside your house on a warm evening and pay attention at your home’s foundations. Carpenter ants love ‘going out’ on warm nights which gives you the chance to feed them with the magic granules before they start visiting you without invitation.

Diatomaceous Earth

Diatomaceous Earth

Are you currently hunting for the best pet safe indoor ant killer that is also nature-friendly and non-toxic? A great quality ant killer product that contains diatomaceous earth is just what the doctor ordered. Diatomaceous earth resembles white talcum powder.

Basically, it’s a type of sand that consists of nothing but fossilized remains of tiny, aquatic organisms called diatoms. Finally, you’ve found an entirely natural and extremely effective ant killer which is allowed to be used around pets and kids.

To start using diatomaceous earth for your ant-eliminating purposes, sprinkle it by hand in any problematic locations: anywhere in the yard, near various cracks or holes, in the doorways, or anywhere indoors. A lot of people use diatomaceous earth outdoors as a barrier on the outside of your door to prevent the pests from entering.

Looking to keep unwanted guests away from your garden? Sprinkle diatomaceous earth there, and the ants will soon be literally dead and gone.

Tips on Choosing (and Using) the Best Ant Killer

Are you looking for the best ant killer for both outdoor and indoor use? You’ve come to the right place. In this section, we’ll guide you through the parameters according to which we form our ant killer product suggestions. There are various types of products for ant control. Your ultimate choice depends on your circumstances and the types of ants that are hanging out getting all comfy at your home.

What to Consider When Choosing Ant Killer Remedy?

Before buying the very first ant trap that catches your eye, consider the following crucial questions:

  1. What type of ants do you have?
  2. Where do you want to use the bait?
  3. Does it matter to you if the ant killer product you’re about to use is eco-friendly or not?

The thing is, what attracts one type of ants could be totally useless against another. Carpenter ants, fire ants and thief ants love a protein rich meal. As for sugar ants, they are more interested in sugary food. Make sure you check the packaging of your ant deterrent before you make any purchases. The packaging should indicate the type of ant the product is designed to kill. There are also broad-spectrum ant baits, they work for many types of ants.

If you want to opt for the most cost-effective solution, choose the product that combines protein baits with the sweet baits. If you’re intending to buy the ant remedy for both indoor and outdoor use, make sure the product description says it’s waterproof and allowed for outdoor usage. Avoid purchasing granules if the ants are coming through the cracks in the walls. If you have pets, make sure you opt for the best pet safe ant killer.

Remember that, unlike sprays, ant baits are for bigger ant problems. Ant sprays are ideal short-term options. For instance, when it comes to dealing with a few random ants in your kitchen, a good ant spray is a great solution.

The problem gets bigger when you start seeing ants in your house on a regular basis, even after using spray to eliminate them. In this case, start using a bait. Your ant bait will attract more ants at first. No worries. Just let it happen and soon the problem will be solved.

Prevent Ants From Infesting Your Place

Curious about the reasons why you have ants in the first place? It’s simple: ants are searching for something yummy, and your home definitely has a lot of various delish goodies. Most likely a queen set up a colony near your property.

Just like many other creatures, ants seek a comfortable environment to stay warm, find regular access to food and water and reproduce. Remember that the fact that a house is invaded by ants usually has very little to do with how clean or how dirty it is.

Even though ants are harmless, they are highly unwanted neighbors. Keeping your home ant-free requires specific efforts and they all come down to one magic word — prevention. In fact, prevention is the best (and the most cost-effective) way to prevent ants from even deciding to visit your property.

Properly applied sanitation measures alone can greatly contribute to maintaining a clean ant-free environment at your home or any other type of property.

What natural remedies can I use to kill ants?

You can make effective sprays and bait stations out of natural ingredients. One of the most effective substances for fighting ants is vinegar, the particular type of it is not important. Better use one of the cheap kind, because you may need a lot of it.

Clean your apartment with vinegar and water solution spray to make ants’ trails lose their smell. Try to find the nest and spray it all over. Just remember, that sprays of this kind don’t kill ants, they just make them uncomfortable. Below you can find more spray recipes:

  • mix one part vinegar and one part water, add a little peppermint oil;
  • brewed wild chamomile works well for disinfection;
  • mix 1/4 cup of orange essential oil, add a little bit of molasses, one teaspoon of dish soap, and three glasses of water.

If the ant problem is bigger than sprays can solve, you can make natural ant baits. To make a bait station you will need Borax, boric acid or diatomaceous earth, and sugar or something as sweet and attractive for the mix. Such a trap must be changed once in two or three days. Here are a few recipes:

  • mix one part boric acid and one part honey into a bait paste;
  • mix one spoon of boric acid, half a cup of sugar, and a glass of water;
  • mix one spoon of peanut butter, one spoon of sugar, and Borax;
  • mix one part diatomaceous earth (Harris works great on ants) with one part of cereal or nut powder.

The easiest way to stop the ants when there are still few of them is to find cracks and holes, from which they come and put some coffee, cinnamon, or cloves into them. Some people recommend baking soda based traps, but they’re no more than a myth. Baking soda is of no harm to ants.

What Are Ant Prevention Tips and Techniques?

Below you will find some prevention techniques and hacks provided by our pest control professionals.

  1. Keep all your surfaces clean. That way, you will make it difficult for your ants’ friends to follow the so-called ant trails to find their way to your kitchen and food.
  2. Vacuum on a regular basis. Focus on the carpets and under-furniture areas.
  3. Keep your trash sealed. And don’t forget to regularly remove open garbage.
  4. Store your food properly. Ants are mainly attracted to your food. So make sure you keep it in airtight containers.
  5. Keep your gutters clean. Gutters provide a cozy warm environment for the ants. So make sure you keep a close eye on the moist areas around your home.
  6. Clear vegetation and remove wood piles. Rotten wood is what ants adore, so make sure you keep it away from your property. The same goes for trees and shrubs — make sure they don’t touch your house.
  7. Prevent juice spills. Wipe all spills immediately and deprive the tiny enemy from the opportunity to feed on your leftovers.
  8. Eliminate easy entry through cracks in the walls.

Found ants in your home? Don’t fret. A lot of people have to deal with this problem at some time or another. Using a mix of the above tips, hacks and techniques will help you keep your ant problem under control. Wondering if it’s possible to get rid of ants for good?

Permanently stopping ants from entering your home is not very realistic. However, with a good indoor ant killer solution, you will manage to effectively solve your ant problem on your own, without having to splurge on hiring a pest control professional.

    It took me one day to get rid of all the ants in my house. I have found the best product for killing ants here. It is called Terro liquid baits. But if you need something for your yard, this one may not actually work. As for the house, it proved to be very effective. I disagree with Nicholas here: he said that it takes some time to kill all the ants. Terro killed ants in my home in one day!

  2. I have never thought that there are so many guidlines to picking ant insecticide. I didn’t even know that there are different kinds of ants. And this is why I was shocked to see an ant army at my doorstep. They were not small like the ones we see in parks. They were gigantic! So I read your advice here and ordered BASF 396153 Advance Granular. My brother used this bait and it worked!

  3. The problem with ants became almost global. They came from neighbors. Sprays and other ant killing products gave a temporary effect. Other stronger means were impossible because of my dog, and ants regularly climbed into his bowls with food and water. I read about the TERRO Liquid Ant Baits and decided to try them, although I did not believe in the effect. However, TERRO helped me to cope with the ants problem, and the dog is also okay.

    I found an “ant nest” in my front yard, approximately 16″ in diameter, and 4″-5″ high. I prepared two gallons of triazinone and two gallons of malathion (double strength each), and poured them in the “holes.” There were about a dozen “holes” that while drenching them, were about 1/2″ – 5/8″ in diameter each, and when pouring the liquid down them, the FOUR GALLONS did not even come up to the surface on any of them! After drenching the big holes, I covered the area in 1.5# of diazinone crystals, then used a paver and crushed the “ant dirt” down to the ground surface.

    Approximately 10 minutes later, there were only about a dozen ants that made it to the surface. Have I done enough damage to kill off this HUGE nest, or is there something further I can do in the future? I was going to pour 8 ounces or so of lamp oil down the holes and ignite it.

    The nest is located approximately 10 yards from my house itself.

    Could you advise if I have possibly treated the area adequately, or should I purchase an additional ant killer to treat the area? This front yard is not used by any pets or children, the entire neighborhood is “child free” and pets are walked on a leash on the streets and to parks about 1/4 mile away, so there is no danger of human or pets being affected.

    Thanks for any information. To “pour” the liquid on the area, I used a one gallon old “Dawn Detergent” bottle, and as I said earlier, using that to douse the area, I opened up a dozen large holes which I filled thuroughly, but did not “fill” any single hole, it simply kept draining down into the holes.

    All my best,
