If you’ve worked hard on growing the most luscious grass possible and know that you take care good care of your lawn, it can be ruined in an instant when you spot an anthill. Anthills can be large, make a lot of mess, and do serious damage to the grass that surrounds them, but how are they created?

When ants tunnel into the ground, the subterranean structures they create cause a lot of excess earth. As the ants don’t want this earth clogging up their underground tunnels, they bring it back up to the surface and leave it there.

Eventually, the pile of the earth is so large that it forms a mound or hill, and it’s located at the entrance of their tunnel.

Tips for Preventing Ant Hills

Tips for Preventing Ant Hills

Ants aren’t too picky in choosing a home but there are some things you can do to deter them from creating tunnels underneath your lawn. Here are a few ways to ensure that ants don’t start making a hill on your grass:

  • Mow your lawn: Keep the vegetation to a minimum and cut your grass regularly. If ants feel that they’re exposed, they’re less likely to choose that spot to start tunneling in.
  • Use dish detergent: Spray your lawn occasionally with a dish soap and water mixture that’s gentle on the grass but may deter ants. As a bonus, dish soap can prevent weed growth as well.
  • Get rid of food: Whether you throw food scraps on the lawn or feed birds some seed, ants will be attracted to these morsels. Avoid placing any food sources on the grass and they won’t want to come near.

If the ants have already done the hard work and created a hill on your lawn, you have a few options to get rid of them. These are natural solutions that are safe to use around children and pets but will effectively remove ant hills from your lawn.

  • Water: Turn on the garden hose and spray a steady flow of water directly into the anthill. You’ll need to leave it on for a few minutes so that it can fill the tunnels completely. Once it starts pooling on top, leave for another few minutes to ensure it’s done.
  • Vinegar: Pouring vinegar directly into the anthill can throw them off the scent and kill the insects upon contact. If you want to reach further down, make a mixture of at least a few gallons. Be careful with vinegar coming into contact with your grass though, as it will kill the leaves.
  • Dish soap: A simple combination is to mix dish detergent with water and pour it into the anthill. You’ll need to take the top of the anthill so you can see directly into the tunnel entrance, and have a few gallons to pour into there for it to work.
