Nippon Ant Killer Powder

Nippon is probably the most well-known product for killing ants in and around the home and garden. It has always been my ‘go to’ choice and remains the best ant killer on the market.

As well as killing ants it is also effective against other crawling insects such as earwigs, woodlice and silverfish. It is safe to use around animals and so pets need not be excluded from the treated areas.

The Nippon Ant Killer Powder is very easy to use. It comes in a bottle with several small holes in the top and you shake it out like talcum powder You can dust it along door and window frames and any other crevices through which ants are accessing your home.

You can also dust it around the garden wherever you see signs of ant runs or evidence of nests. Occasionally the holes get a little clogged but simply banging the bottle on a hard surface will soon unclog it and get the powder flowing again.

The ant killer gets to work quickly, and you will soon see fewer ants around. It can take a couple of days to get rid of the ants completely, but it is long lasting, and it is unlikely you will have a problem with ants for several months after use.

The bottle is 150 g which is enough for several applications so one bottle will last a long time. Nippon Powder provides a simple to use, cost effective and long-lasting solution to the problem of ants in the home and garden. It’s the best ant killer for the UK market.

Home Defence Ant Stop Bait Station

This Home Defence Ant Stop Bait Station comes with two bait stations which are easy to use. You simply position them close to where the ants are getting into the home. The ants are attracted to the stations and then some of the ant killer sticks to them. They take this back to the nest and it kills off the whole colony.

I have found that this product is quite handy if you want something you can tuck away out of site. It saves having powder spread about which can get trodden around the home. You can also position the traps outside.

I placed one of these traps in my front garden as there were literally hundreds of ants crawling around and finding their way indoors. At first, I noticed more ants. This is probably because the trap actually attracts them. However, a couple of days later there were no more ants to be found.

This product is very simple to use and creates no mess or fuss. If you are looking for the best ant killer to effectively deal with ants in just a few days, you will be impressed with this product!

Home Defence Ant Stop Granules

The Home Defence Ant Stop Granules are for use outdoors only. I had a problem with ants on the patio, crawling all over me and my family every time we sat outside to enjoy the garden. This was particularly unpleasant when we were eating outside so I needed to act.

The product is in the form of granules, in a sugar-based carrier which attracts the ants. The granules come in a cardboard canister with a plastic lid, like the packets salt crystals come in. The granules themselves look just like sugar. The instructions advise piling the granules up near the nest site or mixing the granules with water and pouring into the nest.

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. They then take the granules back to the nest and this kills the whole colony.

For the first day after I applied this product, there were actually more ants on the patio. Presumably, this is because they were attracted to the sugar. However, after three days we had gone from hundreds of ants on this 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 if the ants do come back.

I like the versatility of this product as it can be applied as granules or diluted and poured onto nests making it suitable for a range of ant infestations. Another fine example of the best ant killer for the UK market.

Rentokil Ant & Crawling Insect Spray

This Rentokil Ant & Crawling Insect Spray is easy to use and effective against a range of crawling insects. I used it to get rid of the ants that were invading my kitchen and it killed them all on contact.

The product comes in a bottle with a mist spray and a jet spray. I found the mist spray to be perfect in the kitchen. I was expecting to be confronted with more ants over the next few days as this product is not taken back to then nest. However, I was pleasantly surprised that the ants seemed to stay away, and I haven’t had any of them in the kitchen for a couple of weeks now.

This is a great product if you want something to instantly kill ants that are crawling around patio areas or inside the home. It’s a little more expensive than the powders and granules but it is very easy to use and delivers instant results.

This is the best ant killer for the UK for both indoor and outdoor use and delivers instant results.

Buysmart Ant Gone

This Buysmart Ant Gone comes ready to use in its own watering can. It contains 5 litres and is effective against ants and other crawling insects. Apparently, it can even be used against ticks, fleas, mites and mosquitos but I can’t testify to that.

I decided that this could be the solution to several ant’s nests in my lawn.

This product is simplicity itself to use. Simply open the bottle and pour it over the ant’s nest. You can also use it on paths and patios when you can’t get to the nests itself. Apparently, this product can also be used indoors but I am not sure how feasible that would actually be if you didn’t want to drench your house.

This was extremely effective at killing all the ants in my lawn. The ants were gone within hours and I have seen no sign of their return at these sites in the last few weeks. If you are looking for a simple, easy to use product, this might be the best ant killer for UK gardens.

Ant Killer Buying Guide

While ants are not the most terrifying pests, they can create problems if they become too numerous, especially if they decide to move into your home! A few ants might not be a problem, but there is rarely just a few: they seem to invade in their hundreds. I really don’t like killing things, but we were recently overrun with ants in both the front and back garden and they had started to invade the house in force, so something had to be done!

Luckily, there is a range of products designed to eradicate ants from your home and garden. Ant killers come in two main types. The first are sprays, which kill the insects on contact. This gets rid of the ants that you see immediately; however, it does not affect the nest, so you may soon have more ants.

The second type includes powder, granules and bait traps. These work by attracting the ants who get some of the power or granules attached to them and then they take the product back to the nest, eventually killing the whole colony. You may need to wait a few days until the ants completely go, however it is often a more long-lasting solution than using a spray.

I have tested some of the most popular products in various places around my home and garden to see which ones eradicate ants the most effectively.

Read the product description and label of each product carefully to check it is suitable for your needs. The ant killers in these reviews are safe to use around the home, however, it is wise to keep an eye on children and pets to make sure they do not ingest the product.

If you choose an ant powder or granules apply when the weather is dry for the best effects. Whatever treatment you use, check for signs of infestation every 30 days to keep these pests at bay.


I don’t mind ants in my garden, but I don’t really want them coming indoors. How can I discourage them without using insecticides inside my home?

Ants usually come inside because they are attracted by food. They may be less likely to come in if there is no source of food, especially sugary foods, available to them. Keep all food stuff in airtight containers or in bags sealed with secure clips or ties. Rinse out containers before putting them in recycling bins and wipe and dry kitchen surfaces after preparing food. You might want to keep sugary foods and drinks such as squash and jam in the fridge.

You can also spray a lemon or vinegar solution around the areas that they come in and out. This will at least temporarily disrupt them.

To ensure your home remains free of ants you can use one of the granules or powders in the above reviews and sprinkle it outside your house at the places that ants are gaining access.

Are ants actually harmful?

Ants are not the most harmful of pests, however, they do bite and they can also cause damage to plants and lawns.

I don’t want to use an ant killer. Is there another way to kill ants?

If you only have a small infestation of ants you could try using a vinegar or lemon solution to get rid of them. However, as a single queen ant can spawn thousands of eggs every day, and ant mounds can contain up to 200,000 ants each, the only way to truly be rid of them is to wipe out the colony with a product specifically designed for this purpose.
