There must be something that is attracting them. There are few considerations that you can check to identify the cause of the problem.

  1. The location of your garden. If there is any cold shady spot then it is more likely to attract red ants on a hot summer day.
  2. Soft fruit and vegetable seedlings. Red ants are attracted toward soft juicy vegetable seedlings. Actually, they don’t feed on these seedlings. It is a good resource for farming fungus in their base. Yes some of them own fungus farms.

Are Red Ants useful to the garden?

Yes, Red ants are useful at least to some extent.  A limited number of ants can control the population of other insects, bugs, larva, and grubs. Otherwise, these creatures may have fed on your plants.

Ants make colonies below the ground. They create a network of interconnected tunnels. These tunnels can help the air, water, and nutrients to reach the root system. Once they leave any colony, this space is utilized by the root system.

Ants can easily break down dead and decaying organic matter like any dead insect. It can help in the faster decomposition and the residue is the best organic compost for the plants.

It can increase the chance of infection in the roots and stunt the growth. In the worst case, the plant or tree may die without nutrition or moisture.

They can cut the small seedlings and damage the root system. Ants may move tiny seeds and end their chance of germination.

Too many red ants in the garden can reduce the population of natural pollinators. They will hunt for larva and caterpillar of moths and butterflies. They can even kill small birds and their eggs.

How to get rid of red ants in the garden?

You should be aware of the fact that killing ants is the last option. There are many alternative options available to get rid of red ants in the garden. You should remember that killing is not an option.

We should never kill ants just for the sake of killing.

These small creatures are part of the garden ecosystem. your intention should be to keep the population in control especially in your garden.

Distraction is always better than killing. It is a slow but less cruel method. You can lure ants to any empty corner of your garden with sugar cubes or any sweetener. They will keep returning to find easy food sources and the rest of your garden is safe.

Also, try to keep your garden free from pests especially aphids and mealybugs. They act as a food source and no food will force them to move away.

Ants can be easily distracted by-

  • Easy food sources like sugar syrup or honey.
  • Some spices can also distract ants. Asofetada is the best spice to dither ants, they hate its fragrance.
  • Sometimes Spraying onion garlic oil near their colony can distract them.
  • Finally, you can try some insect repellent plants to avoid red ants.

Finally, if their population is out of control then kill is the only option. You can either use-

  • Ant poison or gel.
  • Boiling water.
  • Professional help.

As I have already said- Elimination is the last option. Try these techniques only when there is no other option available.

  1. You can use a mixture of borax or boric acid with sugar syrup or cornmeal. This will not kill the ants instantly. Instead, they will carry this mixture to their queen. And together they feed on it. Ants can’t digest the borax mixed sugar. Eventually, the queen and her soldiers die. This method is effective every 1 out of 3 times.
  2. You can put boiling water over the ant colony. You may have to repeat this step several times as ants are prepared for flood-like situations. It is an old method and seems very effective. But there is a practical problem. Ants can make their colony as deep as 20 meters and this can cover several feet in width. So boiling water will not work in a big ant colony.
  3. You can also try Ant poison gel. This will act as a luring agent and attract lots of ants. They will feed and eventually die due to dehydration and starvation. Again this method is only effective if you have a sufficient amount of gel so that it can be taken to the queen before distribution.
  4. The fourth option is also an Ant poison but in powdered form. This Poison is effective in killing, distracting ants for a long time. But it should be applied indoors and can harm the soil. So most professionals do not use this type of poison.  It can do more harm to us than to the ants.
  5. Diatomaceous Earth (DE) is a powdered form of fossilized diatoms. They can quickly dehydrate moist insects and kill them. It should be kept dry to work perfectly. This material is of no use in the rainy season or moist location. It can be harmful to both humans and pets if inhaled. DE or Diatomaceous earth is not always effective for red ants.

What kills fire ants in the garden?

There are many chemical inorganic means to kill ants. To kill fire ants in the garden you have to introduce their natural predators. They will keep feeding on these ants and control their population naturally. The most common natural predators of red fire ants are-

  • Frog and toads.
  • Nematodes
  • Lizards & chameleons
  • Birds.

Frogs and toads need wet soft areas to hide. If your garden has a spot like that then you can introduce them as a control measure.

Nematodes are the easiest option to introduce in the garden. They are tiny worms that can repel and kill several infectious pests. Nematodes can control the population of ants, moths, and giant beetles.

They first enter the body of the host (an ant) and release several bacterias to neutralize it. Then feed on it from inside and lays eggs. eventually, the ants get killed by the nematode. Meanwhile, the ant will carry these worms inside their colony and risks the life of the queen ant.

The dying ant also releases some pheromones or scents to inform the colony about the invader. This will eventually force the colony to leave the space.  They can’t live with their natural predators.

Sticky Ant Traps can also kill some ants but it is not very effective for large furious red fire ant colonies.

They don’t like the smell of these oils so they try to keep away from it. You may have to spray this solution several times over days to get rid of red ants in the garden.

The final and the most effective method is here. Use Asafoetida with Antiseptic solution like Dettol and water and spray near their colony. This method will work for almost every type of ant. It will not kill the ants but force them to leave the colony. The smell of asafoetida and antiseptic solution reacts with their pheromone sensors and creates a sense of danger. Therefore they are compelled to leave the colony. You may have to repeat the application for several days for 100% success.

It is a natural selection process. One colony is killed and destroyed by another ant colony. So it more likely that you will see them again after a few weeks or more.
