Ants are such a nuisance and when summer rolls around, they come in their hundreds and get into places they shouldn’t.
To save you the drama of going through different products looking for the best ant killer, we’ve rounded up effective products that will do the job. Don’t forget to check out our review and buying guide!
Product Testing & Comparing
We reviewed the best pest control options for homes overrun by ants. Comparing them was tough but in the end, we selected the best and ranked them according to a strict set of guidelines.
- Versatility (with other pests)
Undoubtedly, the effectiveness against ants is the most important aspect of these products. But safety and cost-effectiveness (mostly supported by long-lasting applications) are also important. We ranked the products with our favourite at the very top, although we found them all to be excellent products.
As a note, often the safety qualifier will be lowered in our rankings – this is due to being unsafe for aquatic life. Anything that’s toxic to pets or humans will get no higher than a 5, and we’ll explain it in the product’s section.
That being said, the top 3 are especially useful if you want a single product that offers you long-term solutions.

The Best Ant Killer
- Targets: Ants, cockroaches, wasps, and more.
- Type: Powder.
- Special feature: Applications last up to 6 months.
Easy to use and effective, ants will fear this killer.
Our team of reviewers voted this powder as the top choice to deal with an ant infestation in and around your home. It contains highly active ingredients which makes it a powerful agent against ants but also other bugs. Indeed, we found that the handy bottle also deals with pests like cockroaches, earwigs, beetles, silverfish, woodlice and many other crawling insects.
With a long-lasting effect, you can expect weeks of no ants both inside the home and outdoors. Despite containing permethrin (a durable insecticidal compound), the powder is safe for both children and pets. It’s also straightforward to use; just dust onto points of access, like window frames, doorsteps, cracks and crevices and the best ant killer powder will do the rest.
Our reviewer was a huge fan of this ant killer. While it’s toxic to aquatic life, this can be remedied with careful application that won’t run off with rain. Otherwise, it’s incredibly long-lasting, easy to apply, and safe for children and pets while being applicable to a number of pest insects.
- Easy to apply.
- Safe to use around pets and children.
- Long lasting effects.
- Suitable for both indoors and outdoors.
- Will probably work on carpenter ants, fire ants, and a lot of other ant species.

The Best Heavy Duty Ant Killer

- Type: Powder
- Special feature: Kills on contact.
Fast and indiscriminate, you’ll be pest-free in no time with this killer.
Our team was so impressed by the powdery success of the first product that we decided to list another powder repellent at number 2. So, if this is also your preferred type, here’s what our reviewers liked about this shaker!
Defenders Ants Powder gives you a highly effective ant killer that eradicates more than ants. You can also control cockroaches, woodlice, earwigs, silverfish, and bedbugs. It comes in an easy to use puffer container that allows faster delivery to the required area.
If your problem is severe, then there is hope. This powder kills pests on contact, preventing them from running away and multiplying. Its highly-effective formula contains permethrin, which is toxic to ants and other insects.
Our verdict? It’s a great powder to use around kitchens, patios, garages, gardens, and storage units. While it doesn’t last as long as #1, it’s still a highly effective insect killer – just keep it away from fish and other aquatic life.
- Kills quickly.
- Easy to use and store.
- Suitable for applications in cracks and crevices.
- 1 bottle treats up to 25m² of space.
- Very indiscriminate. Can kill non-pest insect species.
The Best Ant Killer For Nests
- Targets: Ant nests.
- Type: Granules.
- Special feature: Attracts ants with a sugar-based carrier.
Sweet but deadly, this will be an ant favourite – until it isn’t.
We get it. Sometimes, destroying a line of ants marching across the window sill won’t stop the invasion. We looked for a product to deal with pretty severe problems where the entire colony needs to go. Our reviewers looked at several options but selected these granules as the top nest bomb.
Specially formulated with an attractive taste and long-lasting effect, ants take the poison back to their nests where the granules keep on working.
The granules can be applied by hand directly into open nests or mixed with water in a watering can for cracks and crevices. This product is so powerful that sometimes all it takes to exterminate a nest is a single application. It is supplied in a convenient shaker container for those who do not wish to come in direct contact with the granules.
Our reviewer was a very big fan of this bad boy. While it’s primarily targeted at ants, it’s effective against a number of insects – just not as much as it is with ants. It is harmful to aquatic life, so once again, keep it away from streams or other water sources (and any swimming friends or pets).
- Contains ingredients that kills colonies in a single application.
- Irresistable to ants.
- Designed to be carried back to ant nests.
- Can be used as granules or diluted in water.
- Harmful to aquatic life.
The Top Ant Bait Station
- Targets: Ants.
- Type: Bait stations (4).
- Special feature: Reduces ant activity within 3 to 6 days.
Safety for your furry friends is guaranteed with this pest killer.
If you prefer something cleaner or more contained than powder and granules, then a bait station is a great alternative. With this offer, you get 4 stations that you can place throughout your home. The traps are designed to attract ants, so you don’t have to do anything else but place them near problem areas.
The traps contain contains fipronil, a slow-acting ant poison that gradually takes effect from the moment of contact up until the ant gets back to the nest. This feature guarantees the elimination of the entire colony within 1-3 weeks. Each bait station also lasts for up to 3 months.
While this is focused on ants it does work for several other types of pest, but the big bonus here is that the key ingredient here, fipronil (this is a long study that essentially says in small doses, fipronil is safe for cats and dogs). Add in the long-lasting duration, and this is a great product.
- Slow acting poison ensures the bait is carried back to the nest.
- Ready to use.
- Can eliminate an entire colony .
- Sealed container protects pets.
- Suitable for both indoor and outdoor applications.
- Strong formula that lasts up to three months after opening.
- Breaking off the snaps requires a little extra effort.
The Best Ant Spray
- Targets: Fleas, ants, cockroaches, earwigs, bedbugs and flies.
- Type: Aerosol.
- Special feature: Effects last for days when sprayed on a surface.
Dangerous to most life, this does the job – use it with caution.
If you prefer a spray, Rentokil offers something that is perfect for combatting ants and other bothersome insects in your home and garden. After our team took this home and put it through its paces, we are happy to say that it effectively gets rid of things like ants, wasps, lice, cockroaches, fleas, and bedbugs.
Offering you long-lasting protection, the spray is easy to use, fast-acting and can be applied in cracks, bedroom areas, skirting boards, garages and many other problem areas. The persistent residual activity, largely due to permethrin and d-allethrin, keeps your surfaces and other places free of insects.
While this is a very effective, long-lasting, and versatile pest killer, it is toxic to children and pets. This dropped it in our rankings quite a bit, but it’s so good that we felt it should be included somewhere on the list.
- Potent, long-lasting insect-killing compounds.
- Easy to use.
- Effective against a wide range of insects.
- Must be handled carefully around pets.
The Best Large Liquid Ant Killer
- Targets: Ant nests, crickets, ticks, moths and more.
- Type: Liquid.
- Special features: Disinfects area for up to 3 months.
Long-lasting and effective, this will kill most pests.
This product is a great choice if you have a big ant problem and you prefer a ready-to-use liquid solution. The can, which contains 5 litres of ant killer, acts as a watering can (a feature that our team found especially useful). You can simply pour the liquid without preparation or adding any attachments.
The fast-acting liquid eradicates entire ant nests but can also get rid of other insects around the home. You can use it against crickets, cockroaches, ticks, bedbugs, booklice, silverfish, mosquitoes, moths, mites, beetles and centipedes in and around your house. One bottle covers up to 50ft² and the effects last up to 3 months after application.
This is quite an effective pest killer. It works on a wide range of insects and does its job well and for up to three months. While it smells strong, it will do its job. So if you can get over the smell (why our reviewer put this in the latter half of the list) you’ll love this.
- Fast acting.
- Long lasting.
- Fights wide array of species.
- Suitable to use inside the home and garden.
- Works on both porous and non-porous surfaces.

The Best Hand Pump Ant Killer Spray
- Targets: Ants and other crawling insects.
- Type: Liquid spray.
- Special feature: Suitable for pet bedding.
Safe yet deadly to pests, this is sure to please.
Since some of our reviewers are pet lovers and owners, they had a valid concern. How safe are these ant killers around our pooches? After scouring the top options, we selected this ready-to-use liquid that can be safely used on pet beds to kill both ants and fleas.
The handy and ergonomic spray bottle contains 750 ml of fast-acting agents that kill on contact, a bonus if you want to get rid of fast critters like cockroaches and fleas. Besides pet bedding, you can also use this product on soft furnishings and in food preparation areas.
First things first – this can and will kill aquatic life. That’s nothing new for this list, but worth noting. Other important things of note include its relatively limited active duration and limitation to crawling insects. Otherwise, it’s so safe that you can even use it in food preparation areas for ants and other pests.
- A handy spray bottle.
- Ready to use.
- Suitable for pet bedding.
- Kills quickly.
- Highly toxic to aquatic life.
The Top Bait Stations with Refill Tubs
- Targets: Ants.
- Type: Bait stations.
- Special feature: Comes with refills.
The “fire and forget” method works great, thanks to these simple traps.
We loved this baiting system because it comes with two handy and well-designed stations and also 2 tubes of bait to refill the traps. Together, they offer you a long-lasting solution to reduce the number of ants in your home and other problem areas. At its most effective, you can expect this liquid ant bait to completely exterminate a nest within 10 days.
Our team also appreciated the thought and cleverness that went into the creation of the bait, which contains a mixture of honey, sugar and Spinosad – the latter being very poisonous to ants while being virtually harmless to most beneficial insects in the environment.
While this is most effective against ants, it’s quite nice due to its safety. It’s organic, safe for kids and pets, and works quite well against its intended target. Its big downsides are that it’s really only effective for 2-3 weeks and that you’ll need to use more bait than originally recommended.
- Slow-acting liquid ant poison ensures the bait reaches the colony.
- Easy to use.
- Organic-based liquid ant bait.
- Will not affect most beneficial insects.
- For optimal results, you may need to use more than suggested quantity of bait.
The Best Gel Ant Bait
- Targets: Ants.
- Type: Bait stations.
- Special feature: Child and pet safe.
Simple and safe, you’ll be free of ants in no time.
If you’re worried about using ant killer products around your kids and pets, it’s essential to get something that is safe. Our safety-conscious reviewers hunted down this useful 2-pack ant station and decided that this was a perfect way to deal with those worries. The system comes with a highly-effective gel bait to deal with your ant problem while it’s specifically designed to give access only to tiny ants.
The bait stations are also ready to use. Each covers a large area, up to 8 sq m, and also helps to eliminate or reduce the size of ant nests. They also last long, offering you an affordable way to control your pest problem.
While this is safe for pets, kids, and most non-pest insects, there are a few issues with this one. It’s toxic to aquatic life (again, I know), can really only target ants, and lasts a middling amount of time per trap. Though it lasts a while when using all traps, each trap has a rather limited lifespan.
- Two stations.
- Safe for pets and kids.
- Safe for other types of insects.
- Long lasting.
- Covers a big area.
- Toxic to aquatic life.
The Best Ultra-Strong Ant Killer Spray
- Targets: Ants, woodlice, earwigs, cockroaches, and fleas.
- Type: Liquid spray.
- Special feature: Kills black, Argentine and pharaoh ants.
Safe for indoor use, this will eradicate common household pests.
Nobody likes ants to suffer but when they are being a serious pest around the home, the best one can do is to get a product that kills on contact. This extra-strong spray instantly kills several species of ants and other insects. Our reviewers also loved the fact that after an area is treated, an application or two can effectively prevent reinfestation.
The bottle is easy to handle and ready to use. You can spray surfaces as well as hard-to-reach places like cracks and behind furniture.
While it’s effective against a wide range of creepy crawlies, this spray is a bit limited in its application and safety. It’s not suitable for outdoor use due to the wide range of nonharmful critters you can harm with it (mostly insects), making it lose points in the safety rankings.
- Comes with a safety nozzle.
- Kills on contact.
- Ready to use.
- Stops ants from coming back.
- Not suitable for outdoors.
Your Ant Killer Buying Guide
If you have a problem with ants and want to resort to using pest control, our guide will help you to choose the best one for your home and situation.
Ant killers come in different forms, each perfect for a particular kind of ant problem. Granules, ant baits and ant killer gel are ideal for eliminating nests and colonies. Granules, ant baits and gels are also very convenient, requiring you just to apply and get on with your business. But, if you wish to enforce a more hands-on solution, liquid insecticides and aerosol can spray is the answer.
Not all ants can be eliminated in the same way as some are harder than others. While common ants and meadow ants can be easily controlled with most of the products on the market, fire ants are much more difficult to control. If your target is a colony of fire ants, go for a product made explicitly for fire ant solutions.
User and Environmental Safety

Also, many products are safe to use around pets and children, though, in the case of liquids and sprays, it is advised to wait until they’re completely dried. If environmental impact is a big deal to you (which you know it should be), then perhaps you need to make sure that’s not the kind of product you’re buying.
