Ant Killer Reviews

Home Defence Ultra Gun (Editor’s Choice)

If you are suffering from an ant infestation, then you need to look for the best ant killer UK. We think you have this in this product. The spray bottle contains 800 ml of fast-acting and long-lasting, effective ant killer solution.

It can be used both indoors, and outdoors and because of the spray bottle and its extensive range, it is ideal for hard to reach areas such as corners or under lips of doors or paving stones.

The solution starts to act fast and can work for up to an impressive three months in dry weather or indoors, or two to three weeks if exposed to rainy weather conditions.

This ant killer is particularly effective against black ants, argentine ants and pharaoh ants and works to eliminate woodlice, earwigs, cockroaches and fleas.


  • For both indoor and outdoor usage
  • Tackles black, argentine and pharaoh ants
  • Active in hard to reach areas
  • Instant action
  • Easy to use, no need to mix solutions


  • It may not be suitable for use all year round

ARDAP Pest Control Spray (Luxury Choice)

ARDAP Pest Control Spray is a great all-rounder as it can tackle almost any kind of insect (flies and other Diptera, moths, silverfish, woodlice and cockroaches) but is especially effective against ants.

It gives six weeks of long-lasting protection from the first application and gets to work immediately! The can contains 750 ml of ant killer spray.

Another benefit of this product is that it is suitable for indoor and outdoor use and can be used safely around animals and in areas such as dovecotes, kennels and bird cages.

The ARDAP Pest Control Spray is more expensive than other products in this review, but it has an extensive range of usage against other insects and is an effective solution to your pest problem.


  • One application can last up to six weeks
  • Tackles a large range of insects
  • Instant action
  • Easy to use, no need to mix solutions

  • It may be toxic to aquatic life

Vitax Ltd Nippon Powder (Best Value)

The Nippon Ant Killer Powder is a competitive product in this review, not only for its value for money as a solution to your ant problem but also for its long lasting-properties! For example, one application of this product gives you up to six months of protection against ant infestations and other crawling insects!

It is easy to use, just apply a dusting of powder to the mouth of a nest and along any ant trails, cracks and crevices, and it will kill ants instantly upon contact.

Another key feature of this ant killer powder is that it is safe for indoor use and outside and suitable for application in a household with young children or pets. This is a key feature to consider as you want to feel safe in using a product to repel ants.

This powder can even be used on wasps nests, being careful, of course, to apply it without disturbing the nest! However, please be aware that this ant killing powder is also harmful to bees and should be used carefully.


  • Long-lasting, effective action of up to 6 months
  • Pet and child-safe formula
  • Active for both indoor and outdoor usage
  • Efficient for ants and other pests
  • Perfect for cracks and crevices


  • Toxic to aquatic life
  • It may not be suitable for soft furnishings
  • The top may pop off upon squeezing

Combat Max Gel (Best Easy to Use)

The Combat Max Ant Killing Gel works differently from its competitors. First, you apply the gel to any areas where you see ants entering the property or where there is ant activity. The foraging ants then collect the bait, take it back to the colony and feed it to the larvae and queen ant, effectively eradicating the whole nest. So this is not a product where you will see instant results; it takes three to five days for its full effects to be seen.

The gel is an effective ant control on many different types of ants, from Argentine, Carpenter, Cornfield, White Footed, Pharaoh, Odorous House, Pavement and Little Black ants.

It is easy to use; you just squeeze and apply the gel to wherever it is needed, even hard to reach areas that would be difficult for an ant bait unit or powder to reach. The Combat Gel gives protection from ants for up to one month without you having to have ant traps in your home.

Another key feature of this ant killer powder is that it is safe for indoor use as well as outside; just don’t apply to areas that are cleaned frequently or get wet as the bait will be removed. It is also safe to use with small children around.


  • Ready to use
  • Kills on contact
  • Child safe
  • Indoor and outdoor usage
  • Effective design


  • Toxic to aquatic life
  • May have to reapply after rain
  • Because the powder is so fine, it may be blown away in the wind

Defenders Powder (Best for Cracks)

The 450g bottle gives you 25m² coverage, and all you need to do is point the bottle downwards and squeeze. This will release a puff of the powder into any hard to reach area, crack or crevice. The powder gets to work straight away, killing ants on contact.

The Defenders Ant Killing Powder is also effective against other types of insects such as cockroaches, earwigs and woodlice. It is also safe to use in the home as well as outside.

This product works on contact to kill pests, so it will not eradicate ants unless it is applied directly to a nest. Repeated applications may be needed to stop your ant infestation.


  • It has a large amount of ant killing powder
  • Easy to apply
  • Immediate effect
  • Effective on ants and other insects
  • Indoor and outdoor usage


  • Some may find it difficult to open the lid
  • Multiple applications may be needed
  • Some ants may not be killed

NOPE! Bait Station (Best Long Term)

The NOPE! Ant Killer Bait Station has innovation at its core and prides itself on its safe and environmentally respectful approach to ant eradication. The bait contains a systematic insecticide and an insect growth regulator, making it the only product in this review with a two-stage method. The insecticide has a delayed activation which means that the worker ants can ingest it and then take it back to the nest and feed it to the larvae and queen before it starts to take effect. The insect growth regulator also prevents the larvae from reaching maturity, breaking the cycle completely and preventing more ants from being able to continue invading your home.

The bait stations are simple to use; you simply activate them and place them where you have seen ant activity. The ants will be attracted to the bait, and then they will do the rest. All you need to do is check the product regularly to check when it has all been eaten by the ants and replace if there are any ants remaining.

Another feature of this ant killer is that it contains Bitrex, and what is Bitrex, you ask? It holds a world record for being the bitterest substance in the world but is completely non-toxic and so prevents accidental consumption of the bait by either a pet or child were they to somehow come into contact with it. This is extremely unlikely, though, as the bait station is completely enclosed and designed to be completely child and pet friendly and for use inside the home and outside.

The delayed action of the bait means that you will not see as many ants remain around the area where you have placed the station, resulting in less clean-up from you. Because the station uses gel rather than a solid ingredient, the product can last for up to three months after it is opened!

The NOPE! Ant Killer Bait Station is designed to kill ants of the following species, common to UK homes and gardens: Black Garden Ant, Argentine Ant and Pharaoh Ant.


  • Two active ingredients
  • Environmentally respectful
  • No mess solution
  • Indoor and outdoor usage
  • Long-lasting gel for up to three months use
  • Contains Bitrex to minimise pet and child risk


  • It can be difficult to get gel into the station
  • Ants may be able to avoid the bait station

Zero In Dual Action Gel Bait (Best Bait)

This clever product simply requires you to put down the ant bait stations and leave the rest to the ants! The worker ants are attracted to the poisoned bait, collect it and take it home to the nest where it is fed to the other ants. Each pack contains two of these best ant bait stations so you can position them close to where you see ant activity.

The key benefit of this product is that it is completely safe for both children and pets as the active ingredient is safely enclosed within the station. The two bait stations are also effective for up to three months from first use, so they can continue to attract ants and help eradicate your ant infestations and other insects for all of that time!


  • Safe for children and pets
  • Ready and easy to use
  • It kills the whole colony
  • Suitable for inside and outside


  • Tabs can be hard to snap off
  • It may be toxic to aquatic life
  • Ants may be able to avoid

Zero In ZER964 Powder (Best with Child Resistant Cap)

The Zero In Ant and Insect Killer Powder does what exactly it says on the tin, being effective both as an ant killer and against other pests too, such as cockroaches, woodlice, earwigs and other crawling insects.

Compared to other powder products in this review, the bottle has a slim nozzle that allows you to be accurate with the treated areas, targeting cracks and crevices both indoors and outside and is perfect for problem areas such as doorways and windowsills. It also comes with a child-resistant cap so that you can be confident that the highly toxic substance is completely safe.

This powder works on direct contact with ants, killing them instantly, and can be used as a protective barrier from having ants inside your home. The bottle contains 300g and can cover an area of 15m², giving you a lot of ant killer powder for your money when it is a targeted application!


  • Natural and organic formula
  • It kills a wide range of insects in one go
  • Safe for pets and children
  • No scent
  • It covers up to 15m²


  • The nozzle can detach if the bottle is squeezed hard
  • It can cause an allergic reaction if it comes into contact with skin
  • Toxic to aquatic life

Deadfast 20300502 Bait Station (Best Pet Safe)

The Deadfast Ant Killer Plus Bait Station is rated our best pet-friendly ant killer. It has an innovative active ingredient called Indoxacarb which only activates when the ants ingest the bait, making it a safer product for getting rid of ants whilst also being safe for children and pets. It is also environmentally kind as it doesn’t target other types of insects.

The handy bait stations can be placed either horizontally or vertically, as long as the surface is flat, meaning you can use them on floors, under fridges and sinks, on walls or in kitchen cupboards. You just have to place the bait station near the nest or one of the ant runs, and within 24 hours, the results should be effective. This product is also suitable for outdoor use; usage is the same, just find the ant nest or ant runs and place the stations on a flat surface.

As the worker ants ingest the bait, it is then taken back to the nest and fed to other ants, meaning that the whole colony is infected and killed, ridding you of your ant problem! Another handy feature of this ant killer is that the bait stations are transparent, meaning that you can see the product in action and also when they are low and need replacing.


  • Safe for pets and children
  • Transparent stations to see when used up
  • Works within 24 hours
  • It kills the whole colony
  • Environmentally friendly

What to Look For in an Ant Killer

When you have an issue with insects inside your home, it can be an unpleasant experience, leaving you feeling overrun and frustrated by your failed efforts to get rid of ants. There are also many different products you can buy that tackle the issue in different ways, so how do you know which one is best for you?

Below we have listed out a number of questions for you to consider as you read our ant killer product reviews which will hopefully give you some clarity and enable you to select the right product for the job at hand.

Do You Have Pets and Children?

This is obviously a key question to ask yourself before deciding upon the best ant killer for you! The active ingredients in the sprays and powders can be very toxic on consumption, so it is important to consider where you will be applying the ant killer and whether it is safe for the people and pets sharing your home.

A bait station is a good option for you if you have either children or pets to be mindful of; they are enclosed, so the contents are not ingestible. You can leave the bait station near a nest or where you have seen them indoors or outdoors and then leave it to get rid of ants while not causing any other harm.

Is it Purely an Ant Problem?

Is it just ants that are infesting your home and garden, or are you looking for a solution that will do more than just get rid of ants?

Some products are specifically designed to target ants and others that will also eradicate other insects, such as:

  • Woodlice
  • Cockroaches
  • Spiders
  • Earwigs
  • Silverfish
  • Flies
an insect colony

It’s worth making this decision upfront so that you get the most from the item you decide to purchase. For instance, a bait station is specifically designed for the bait to be attractive to and be consumed by ants rather than other types of insects. A product with a more general application, such as a spray or powder, will have a wider reach for also eradicating other insects and can be a suitable solution for you.

Do You Know Where the Nest or Main Ant Runs Are?

Sometimes you might not know or be able to find where the house ants are coming from, and in that situation, leaving a bait station may be the best option for you as you can leave it near where you see the ants most commonly.

Spray, powder and gel application products may work better when applied directly to a nest or along ant runs when you are able to see where they are. If you know that ants are coming in through a door or windowsill or under a kitchen unit, for instance, you can apply the product and allow it to do its job. They also tend to work well as longer-lasting barriers as well as killing the ants that are there at that time.

Red insects build a nest on the leaves of a tree in the garden

Another thing to consider is, are you looking for the best indoor ant-killer product you can find with the problem of ants inside, or do your ants live outside and therefore you are looking for the best outdoor ant killer? If you have a problem outdoors, then look for a product with a long-lasting, effective action that can withstand weather conditions and continue to kill ants.

Do You Want a Product That Will Act Immediately?

Typically ant killers are split into two ways of working; you have those that kill on contact and those that are ingested by the ants and taken back to the nest to infect the rest of the colony.

The products that are ingested and come in a bait station or a gel are slower to work because they have a delayed reaction in the ant to allow it time to return to the nest before the bait becomes poisonous. So the benefit here is that you will hopefully kill the colony and therefore not require repeated applications to rid yourself of the ants, but it does take anything from 24 hours to a week to be effective.

Using a spray or powder will give you more instant results if you want to be rid of ants quickly.


We’re sorry that you’re currently in the situation where you are looking for the best ant killer UK, but don’t despair as we are confident that once you have read this review and asked yourself a few important questions, then you will be in a position to find the product that is right for you!

Ants and other pests can really unsettle how you feel in your own house, and we want to help you select an ant bait or effective spray to help return your home to how it should be in just a few days; ant-free!

Our aim is that having gone through all of the questions above and read our product reviews, you’ll have been able to find a product that ticks all the right boxes for you. However, if you’re still undecided about the best ant killer for your needs, then you would be well placed to try our Editor’s Choice – the Home Defence Ant Stop Ultra Gun.

The solution acts fast and works for up to three months in dry weather or indoors, or two to three weeks if exposed to rainy weather conditions, in which case you will just need to reapply. It is perfect for use both indoors and outdoors, and it is ideal for hard to reach areas such as corners or under lips of doors or paving stones because of the spray application and its extensive range.

It is a great all-rounder of a product, working against black ants, argentine ants and pharaoh ants, but it also works to kill woodlice, earwigs, cockroaches and fleas.

We hope that we have solved your pest problem and you have found the best ant killer spray in this product – good luck!
