Why are there so Many Ant Hills in my Yard?

Ant hills are made from soil, dirt and other debris that ants clear as they build their underground tunnel system. They take waste, soil particles, organic matter and other materials to the surface. These materials pile-up to form an anthill.

There are three main reasons why there are many ant hills in your yard:

1. Presence of food sources in your yard for ants

Ants are attracted to your lawn if there is reliable sources of food. Ants feed on aphids and other decaying materials in your lawn. They are attracted to the honeydew that aphids produce. Ants will also inhabit your yard when having a compost pile, garbage bins and other organic waste in the garden.

2. Perfect soil conditions for ants

Ants like well-drained soil that is not compacted, which is also required by your grass to grow healthy. They also prefer dry areas that receive a lot of sun. If your lawn is having bald patches of struggling grass, it create perfect nesting areas for ants.

3. Reliable source of water in your lawn

Ants are also attracted to an area with reliable source of water to quench their thirst. Ants will build their nests in your lawn when having leaking underground water pipes, birdbath areas or stagnant water ponds. To keep them away, be sure to get rid of stagnant water and fix leaking pipes.

How to Get Rid of Ant Hills in Lawn (without Killing Grass)

Since anthills typically created by ants, the only way of getting rid of them is to eliminate ants in your lawn. Once done, you can then level your bumpy lawn or fill the small holes left behind by the insects.

There are two major ways you can use to get rid of ants in your lawn without harming your grass. You can control ants naturally with home remedies or with chemical pesticides.

How to Get Rid of Ants in your Lawn Naturally

Killing ants in your lawn can be tricky especially if you are having children and pets playing around the garden. You also have to control them without causing damage to your grass. There are various natural methods you can use to get rid of ants without posing danger to your children, pets and grass.

1. Diatomaceous Earth

Diatomaceous earth is a powder made from fossilized skeletons of diatoms. It is available in industrial-grade or food-grade. Either of them is harmful to ants and friendly to human and pets. It also contain nutrients that are beneficial to your lawn.

You simply sprinkle the powder into the nest and other areas where ants are present. This product work by dehydrating ants and killing them over time. The results are not immediate but you are assured they will die over time.

2. Mixture of Boric Acid and Sugar

The idea behind use of boric acid and sugar is to create a substance that will attract as well as kill the ants. Sugar attract ants as a source of food while the boric acid will kill them. They will take the mixture into their nest to feed the queen. The entire colony will end up dead.

To use this method, you simply use enough sugar and boric acid to create a thick substance. Place the mixture around nest and other places having ants. Wait to see the results.

3. White Vinegar

White vinegar can also be used to get rid of ants in your lawn. To prevent it from harming your grass, mix it with an equal amount of water and pour it into the nest. Using it in pure form can dry out top layer of the soil and damage grass.

4. Chili Powder

Ants will invade your lawn if they feel safe and comfortable. Applying chili powder on their path and nest will irritate them to a point where they give up and move out of your lawn. To increase efficiency of this method, add peppermint in either oil or dehydrated form.

5. Orange or Lemon Peel

Some gardeners will swear on the efficiency of peel from citrus fruits in controlling ants while others have some doubts. However, it’s believed that orange or lemon peel help to repel the ant. It also kill the fungus they feed on. Spreading pieces of the peel around their nest can help to drive them away.

6. Destroy their Nests

Destroying nests will send a message to the ants that they are not welcomed in your lawn. However, you should be careful when destroying the ant hills to avoid damaging the grass. For instance, do not use a shovel or spade to scoop the soil. Instead, use a brush to disperse the soil within your lawn.

Prevent the ant from re-establishing their nests using a bait station. Bait station contain poisoned food that attract the ant. They will feed on poisoned food and take the rest to into their nest to feed the queen. The poison will end up killing the entire colony.

How to get rid of ant in your lawn by use of chemicals

Chemical pesticide are highly effective in killing the whole ant colony without harming your lawn. However, they are not suitable for use when having children and pets playing in the lawn. They can also harm the environment and damage your lawn when used inappropriately.

Chemical pesticides come in different forms such as granules or soluble liquids that are sprayed into the nests to kill the ants. They include the following:

1. Ant Killer Granules

Ant killer granules are either sprinkles around the nests and other areas infested or dissolved in water and sprinkled over nesting areas. They are very effective in killing ants through body contact. Depending on the size of colony, it may require second application after a month.

2. Ant Killer Sprays

Ant killer spays are highly effective in killing ants that are visible on the ground. However, I would not recommend you go around your lawn spraying the pesticide as there are other alternatives such as chemical granules that are suitable for killing ants from their nests.

Final Thoughts

It may not possible to get rid of ants from your lawn completely. Insects are beneficial to the health of your soil too. They create burrows that help to aerate the soil as well as improving fertility when they break down organic matter. However, when they start damaging your lawn or invading your home then there is need to control their population but in a manner that will not damage or kill your lawn.
