4 Best Ant Killers to Rid Them From Your Home & Garden (2021 Review)

Dealing with an ant infestation can sometimes feel like an uphill battle. A several-pronged approach is often required to really battle effectively against those insistant armies.

I used the Home Defence Ant Stop! Bait Station in my kitchen, positioning them at two different entry/exit points I’d seen ants use.

What happens is, the ants visit the stations and ant-killer product transfers onto them. They take this back to the nest and it works to kill the colony from inside the nest. Clever stuff hey?!

These Home Defence traps are pretty handy because they provide an ant-eradicating solution that you can a) tuck away out of site, and b) put down and forget about. They save the mess and bother of accidentally treading powder around the home, and will continue working for about 3 months.

If you’re generally reluctant to put down powders or liquid insecticides, these self-contained units are probably the best ant killers for indoors – the access-point holes are only small enough for insects to crawl inside, making these pretty safe to use around the home. However, if you do have pets you will need to make sure they don’t pick up or chew the stations.

The Home Defence Ant Stop Granules are for outdoor use only, so I figured I’d combine this product with the indoor bait stations.

I had a problem with ants on the patio, every time we sat outside to enjoy the garden. This was particularly unpleasant when we were eating outside so I needed to find a solution.

The product is in granular form, combined with a sugar-based carrier which attracts the ants. They come in a cardboard canister with a plastic lid, and can be applied straight from the packet.

The instructions advise piling the granules up near the nest site or mixing the granules with water and pouring the solution into the nest.

In my case, I wasn’t sure where the nest was; however, there were a few places where the ants were most prolific, so I just poured a little pile of the granules in each of these places. The idea is that they the granules back to the nest and this kills the whole colony.

Again, the day after I applied this product there were actually more ants on the patio, likely attracted to the sugar. However, after three days we had gone from hundreds of ants on the patio to just a few. By the end of the week, there were no ants at all. This was a few weeks ago and there have been no signs of any ants returning. It is also a large pack, and I didn’t use anywhere near all of it so there is plenty more, for several future applications, if the ants do come back.

In my opinion, the combination of using this product outdoors and the bait stations indoors worked a treat, and it’s what I’d recommend if you’re experiencing a similar infestation to what I had.

Nippon Ant Killer Powder is one of the most well-known products for killing ants both inside the home and out.

As well as being a very effective ant killer, Nippon is an extremely versatile product; it’s also capable of getting rid of other crawling insects such as earwigs, woodlice and silverfish. If you’re dealing with some form of insect infestation, likelihood is Nippon can be of service.

Unlike some other ant killers, Nippon states that children and pets don’t have to be kept away from the treated area, which is good news if you were concerned about either. However, as with all chemicals, it’s still best to keep curious hands and paws at a safe distance – just in case.

This powdered insecticide is very easy to use, coming in a bottle with small holes in the top – simply shake it out like talcum powder. It can be dusted along doorframes and windowsills, and any other crevices through which ants are gaining access to your home.

The bottle design can make it challenging to accurately get the powder into smaller spaces, but only a small amount needs to be applied successfully to help it be effective.

The ant killer gets to work quickly, and it’s even possible to notice the effect after a few hours. It can take a couple of days to get rid of the ants completely, but the results are long lasting; you’re unlikely to have any problems with ants for several months after use.

Overall, this is an extremely effective product which will essentially eradicate ants, wherever you place it; however, it should be noted that Nippon contains permethrin which can be very harmful to aquatic life. Care needs to be taken when disposing of Nippon, and it isn’t the best ant killer for you if water from your garden runs off into a stream or river.

This Buysmart Ant Gone comes ready to use in its own ant-attacking watering can. It contains 5 L of liquid product and is effective against ants and other crawling insects. According to Buysmart, it can even be used against ticks, fleas, mites and mosquitos.

The easy-application design makes it simple to use, taking the hassle out of applying at-home treatments.

Whereas some other products require decanting and diluting, Ant Gone only requires you to open the bottle and pour it straight over the ant nest. You can also use it on paths and patios when you can’t get to the nests.

Whilst Ant Gone can also technically be used indoors, you’d have to think carefully about how to apply it if you didn’t want to drench your house seeing as it is in liquid form.

However, the fact that it’s liquid does make it easier to apply over larger surfaces than powder products. With a rose-head that helps distribute the product evenly and sparingly, it can be great for use over large patios and lawns.

Ant Gone relies on the product having physical contact with the ants and killing them that way; therefore, it can be harder to get it to infiltrate a nest. Pouring the liquid directly into the nest can be relatively effective, but may require a few applications.

Unlike some other products, particularly those in granule form, Buysmart Ant Gone isn’t carried back to the heart of the nest by the ants.
