Ants usually nest outside and enter the house when they’re searching for food. Sugar and grease ants are the main types that cause problems. Several species of ants fall into these broad categories based on their food preferences.
- Sugar ants like sugar or sweet things (think Pharaoh ants, or Odorous ants)
- Grease ants search for protein or fatty substances (Fire ants fall into this category)
Below we describe the best ant killers that are currently available to resolve your problem in both the short and long term.
Top 10 Best Ant Killers
Here’s a list of the 10 best ant killers that you can buy. Below we also provide a brief description of what each is effective against. This list is in no particular order and you should consider your specific situation and what you aim to get out of them first. Enjoy!
Out of all the types of ant killers there are on the market, we prefer ant traps by a wide margin. Ant sprays are mostly contact killers with very little effect on the ant colony. Granules are ok but require a lot of maintenance, and they are only really effective for outside ant problems. Ant traps continue to be the most versatile solution for ant problems. See below for our top ant killer picks.
Best Ant Sprays
Why it's the best: Raid is a powerful spray that kills on contact. You can use this indoors and it doesn’t leave any nasty odors after spraying it. This contains a powerful chemical that kills ants, roaches, and other pests.
Why it's the best: You can use this aerosol both indoors and outdoors against a variety of ants and other bugs. This kills on contact and claims to have a residual repellent effect for up to six weeks after use. I'd put the TERRO brand slightly above the Raid brand due to the residual effect.
Best Ant Gels
Why it's the best: Advion uses a sweet attractant to lure and later poison ants with a slow-acting insecticide. This works on a wide variety of species and is highly effective against sugar ants. The product has a shelf life of two years and you can use it both indoors and outdoors.
Why it's the best: MAXFORCE contains several, ready-to-use gel baits that are easy to place wherever needed. This can be used either indoors or outdoors and put into the small cracks and holes around your house and garden. This has a residual poisonous effect for up to two weeks after use.
Best Ant Granules
Why it's the best: Amdro granules bait and attract a wide variety of species. The granules have a slow-acting poison that usually kills the queen within a week. The main advantage is that it has a large range and can attract ants over long distances.
Why it's the best: Ortho is an effective and very versatile ant killer. You can expect the bait to work for up to three months after you apply it. The bait also attracts and kills spiders, roaches and several other pests.
Why it's the best: This product kills ants and other insects when they come into contact with it. You should use this outdoors and it can eradicate bugs that you can see and those that are underground. Granules are best used on your lawn for outdoor ant problems. Just be aware that granules have to be prepped a bit before effective use.
What are your ant killing options?
You have a variety of options available to you depending on your circumstances and the types of ants you have.
Some use a bait that has a slow-acting insecticide. Baiting relies on their social nature to carry it back to their mound and poison the larvae and Queen. Other products, such as sprays, kill the ants on contact. Consider if you’re looking for a short or long-term solution before you choose the best ant killer for you.
You can learn more about the behavior of ants and effective management here. Let’s have a look at how some of these products work and how they can benefit you.
First on the list of potential ant killers are the ant traps. Ant traps are the containers the ant bait sits in. Some containers are clear and others are colored. We prefer clear containers so we can actually see if the bait is being eaten or not. Most ant traps come with the bait in the package so you don't have to buy them separately.
The best ant traps mix a slow acting insecticide with something that is highly effective to attract the ants to it. They then take this back to their mound where it later infects and kills the others.
- The most important factor is to make sure that you use a bait in the trap attracts your type of ant. Fire ants and carpenter ants sometimes require a different approach.
- Another factor to keep in mind is that your bait needs to actually attract ants. Many ant killers simply do not attract ants, which of course, is a problem when trying to kill them.
What are ant traps good for?
We like ant traps because they destroy the mound by taking advantage of the social nature of the pests and using this to eradicate the others. Traps tend to be reliable and work on a consistent basis and when the Queen dies, the colony usually follows shortly after.
What are ant traps not good for?
The main disadvantage is that traps is that they attract a lot of ants when you first start using it. This can lead to a larger problem and potential infestation in new areas of your house.
Gels come in a tube with a syringe to apply it into the holes and cracks where the ants enter your house. The gel contains an insecticide that’s spread throughout the colony after they come into contact with it. This works great inside the house and outside.
What are ant gels good for?
Ant gel is great to cover up the holes and cracks that the ants use to enter and blocks them from coming inside. You can use gels in places that are difficult to reach or where other methods are impractical, such as on the ceiling. Most take advantage of baiting to spread the insecticide throughout the colony. In most cases, the gel can stay active for up to a month after you first apply it.
What are ant gels not good for?
Most gels are waterproof when they dry, but this may take a day or two making them vulnerable during rainy weather or in damp conditions. Some people also complain that when the gel dries, it loses its appeal to the ants.
Ant sprays can come as an aerosol that kills upon contact or acts as a repellent (or barrier in some cases). Aerosols contain potent insecticides and tend to have a more consistent effect. You can also make homemade ant sprays using things like vinegar or lemon juice, but they usually aren’t very effective.
What are ant sprays good for?
Sprays should be your go to solution for ants that are causing you an immediate problem.
This makes ant sprays a great tool to combine with other ants killers such as traps or gels in your battle against the pests. Some sprays instantly repel them and they stay away for several hours later. Others use a non-repellent insecticide that kills on contact similar to other baiting methods. Take a look at the video to see how to apply ant spray to your home.
What are ant sprays not good for?
The sprays won’t kill the entire colony and aren't effective against large numbers of persistent ants. Another issue is that the chemicals can be harmful if you or your pets inhale them. It’s also not a great idea to spray near food as the particles may contaminate it. Unless the spray has non-repellent properties, it will just cause the ants to scatter and return later when the insecticide has diminished.
Ant granules use baiting to attract and poison the ants in the mound. You can use these both indoors and outdoors, but you'll probably find granules are more for outdoor ant problems (backyard, garage, etc). They usually retain their insecticidal properties for several days after applying them.
What are ant granules good for?
Ant granules offer a long-term solution and are water resistant. This means that you rely on them to work outdoors in all weather conditions. Another great feature is that they’re safe to use around pets.
What are ant granules not good for?
Ant granules are large and may not be as versatile as other methods. This may result in the ants avoiding them and just going around the granules to find other sources of food. Another issue we have with granules is they require extra work before they can be effective. For example, you'll need to mow your lawn, spread the granules around your lawn using a broadcast spreader, then water them.
What’s the #1 thing to look for in a good ant killer?
The number one thing to look for in a good ant killer is how potent the baiting method is. You want to buy something that the ants find irresistible, works over a large range, and has some kind of a slow acting poison that spread through the mound. Gels, granules, and sprays are okay, but ant traps will usually be your go-to solution.

Our Recommended Best Ant Killer
TERRO ant traps are by far my favorite indoor ant killing method. They are extremely easy to deploy, relatively fast acting, inexpensive, and they just work.
When it comes to outdoor infestations, they can be hit or miss. I'd recommend something like Ortho Ant Killer for outdoor ant problems.
Depending on the level of your infestation, you may also want to combine ant killing products. For example, you can plug up the holes on the sides of your house with ant gel, lay traps inside your house, spread granules throughout your lawn, and apply ant spray anywhere else.
