A yard in your home can be a piece of paradise or a major headache depending on its condition. It’s a labor of love taking care of a yard. So you wouldn’t want any pests showing up in your yard.

But ants are one of those pests that don’t care what you think. If they think your yard is good enough, they will infest it and start building ant hills.

If you live in Perth, dealing with these pests can be particularly challenging. Therefore, in this article, we will go over various ways to Get Rid of Ants in Yard in Perth.

What is Ant Hills?

Ant hill are basically mounds of soil that ants create while they are busy tunneling underground. These hills are signs of their work underground creating homes otherwise known as colonies. 

Ants build these hills for a few important reasons:

  • Shelter: The underground tunnels shelter the ants from bad weather and predators. 
  • Home for the Queen: It’s also a castle for the ant queen that lays all their eggs. The queen needs to be protected; thus, ants build the tunnels.
  • Temperature Control: Just like we need fans and ACs to feel comfortable, the ants need the tunnels to create the right temperature for comfort. 
  • Food Storage: The tunnels aren’t just for temperature control and homes. They also act as a storage space for their food supply.

Dangers of Any Ants Hill In Your Yard in Perth

So you know why ants build ant hills and tunnels. To some, it might not seem like there is any danger from that, but there is. Here are some reasons why you don’t want ant hills in your garden:

Damage to Plants

Ants need food and they might look at your plants as such. Ant hills are a sign of a major population and they can eat a lot. So they might damage your plants for food or the soil around them for tunnel construction. Both of those things are bad for your garden. 

Uneven Soil

Ant tunnels can go on for a time. All the soil they dig can cause your yard to become uneven. This unevenness can cause issues down the line. You might not be able to walk smoothly through your garden. Also you could run into issues when planting new flowers or vegetables. 

Attracting Other Pests

Ants aren’t at the top of the food chain in your yard. There are other animals and even pests that hunt them. They might turn their attention to your flowers or vegetables at some point. This means your garden might get destroyed or harmed. 

Soil Erosion

Ant hills are a major contributor to soil erosion. Due to the tunneling by the ants a lot of soil is moved to the surface. This greatly damages the soil structure beneath your garden and affects the water flow underground. Take too long to get rid of any hills in your yard and you might not have one in the future.

  1. Sprinkle the Powder: Lightly sprinkle diatomaceous earth around the ant hill and any ant trails you see.
  2. Reapply After Rain: Reapply after it rains or if the powder gets wet.

  2. Place the Bait: Put small amounts of the bait near the ant hill and where you see ants.
  3. Wait: The ants will return the bait to their colony, killing more ants over time.

  2. Apply to the Soil: Follow the package instructions to apply them to the soil around the ant hill.

Chemical treatments should be used when natural and organic methods are insufficient to control the ant problem. These is the method most often used by professional ant hill removers. 

Types of Ant Insecticides

There are different types of chemical insecticides available for ants:

  1. Sprays: Use ant sprays to target visible ants and ant hills directly.
  2. Granules: Spread granules around the yard to create a barrier that kills ants.
