How do I get rid of ants in my garden?

There are a number of different organic methods on how to get rid of ants in the garden.

If you have an ant infestation, some experts recommend planting vegetables like garlic or onions near the areas where they’re coming into contact with the ground to stop ants from entering their nest.

Another way that people use is to sprinkle cinnamon on top of the soil around plants and other areas frequented by ants. This method will get rid of ants and all types of insects including slugs, caterpillars, fleas, flies, gnats and more! The downside is that it can take up to two months before this natural remedy starts working so be patient if you want these results.

Some also say that sprinkling boric acid and sugar at entry points may help as well – but this can be toxic to humans and animals so it’s best to use a mask when using the acid.

white vinegar is also a natural ant repellent – but it only works if ants are unable to come into contact with the liquid.


  • Boric acid is natural, organic and environmentally friendly.
  • Garlic, onions and cinnamon are all edible vegetables that will not harm human or animal life if they are ingested.
  • Extremely hot water and dish soap is a cheap and easy solution that will kill all types of insects.


  • Borax is toxic to humans and animals when inhaled.
  • Garlic and onions all take a long time to work.

How do I get rid of ants in my garden without killing my plants?

Ants are a nuisance to any garden and they can be difficult to get rid of. If you don’t want your plants and flowers killed by pesticides or organic methods then it may take some time for the ants to leave on their own.

A great way to prevent ruining your plants is to create a border around your garden. The ants will have to go over the surface of this barrier instead of getting inside it and they are unlikely to find their way across.

You can use bricks, stones, or any other material you see fit as long as it is at least three inches in height (around seven centimetres). This will keep the ants out.

You can also use pyrethrum as a natural insecticide that is non-toxic for people, pets, and plants but still kills both flying insects like flies, mosquitoes, or houseflies as well as crawling bugs such as roaches, ticks, fleas, or any other pests in the garden.

One thing to remember is, you must reapply this every few days because after some time the eggs hatch out new larvae which are not affected by these treatments.

Do we actually need ants?

The answer to this question is debatable; some people agree that we need ants, while others disagree. Some believe that without ants, there would be a lot more dirt and sand everywhere since insects serve as excellent little “sponges” in terms of sucking up the nutrients from decomposing organisms around them.

The dirty water and debris that drips from a large animal’s fur can be caught by the antennae of small crawling bugs, which then uses their mouthparts to rid themselves of the unwanted material and move on.

However, on the other hand, most plants depend on having healthy soil around them while an anthill often produces a chalky form of fertilizer that drains away from plant roots rather than enriched soil for plant growth.

Diatomaceous earth works a treat for a lots of other insect infestations too.
