Can Ants Cause Lawn Damage? (Landscaper Answer)

Ants are an unsightly nuisance that can wreak havoc on your yard, but they’re also efficient lawn care specialists. Ants help aerate the soil and break down plant matter into nutrients that are available for plants to use. 

If your lawn has a large number of ants present in it, however, then there’s likely something wrong with your soil or watering habits.

Can Ants Cause Damage To Your Lawn?

Ants can cause damage to your lawn by eating the grass in your yard and the roots of plants in your garden. If ants are present, they will eat the seeds, leaves and stems of plants as well as their roots. 

Ants can also eat parts of trees including young branches or newly formed buds; this will affect growth rates for new trees planted in a garden setting.

Aeration is a crucial aspect of lawn maintenance, and you don’t always need a machine to get the job done. As we explain in our landscape advice on aerating lawn with pitchfork, using a pitchfork can be an effective and low-cost alternative to aeration machines.

Are Ants Harmful To The Grass In My Yard?

The damage that ants can cause to a lawn are not only limited to their ability to eat away at the roots of your grass, but also include digging up the soil and eating the seeds of your grass. If you want to keep ants out of your yard permanently, follow these tips:

  • Trim any dead or dying branches off trees and shrubs so they don’t attract insects like ants.
  • Keep trees trimmed back from houses and buildings so there’s no place for them near windows or doors that provide entry points for pests like ants into homes or businesses.

What Are The Signs Of Ant Damage On A Lawn?

An ant trail typically looks like a series of small ruts in the grass. Ants leave these trails as they move along, carrying food back and forth between their nests and feeding sites.

 Ants can cause damage to the grass by eating it. In addition, ants may chew on seeds and seedlings in order to access the nutrients inside them for food.

When you see an ant trail on your lawn, there’s a good chance that you have an infestation nearby; however, this isn’t always true! Some ants will leave these trails naturally while they are searching for food or water sources in your yard

If I Have Ants In My Yard, Can They Hurt My Plants?

If you have ants in your garden, they may be harming the plants by eating them or taking nectar from them. Ants are omnivores and will eat both plants and insects, so it’s important to keep an eye on any ant activity around your houseplants and gardens.

The damage that ants can cause to a plant depends on the type of ant involved. For example, carpenter ants tunnel into woody stems or trunks of trees, causing significant structural damage as well as weakening trees to the point where they can fall over entirely during wind gusts or snowfall. 

This type of damage will require professional pest services like ants and termites control to either treat individual infestations or apply preventative measures throughout your property

Do Ants Harm My Dog Or Cat’s Health?

While an ant bite may not cause a serious injury, it can be painful and result in skin irritation and infection. Ants also have been known to spread disease; for example, fire ants are known carriers of the deadly parasite that causes Chagas disease. 

The major concern with ants is the danger they pose to pets who play or sleep in areas where these insects are present. 

Ants love feeding on meat–especially raw meat–and some species can inflict a painful sting when they do so! In addition to causing pain while the wound heals (which could take several days), an ant sting could result in anemia if left untreated by your veterinarian

How Do I Get Rid Of Ants In My Lawn?

If you have ants in your lawn, here are the best ways to get rid of them:

  • Use a spray bottle with a mixture of water and vinegar. The acetic acid in vinegar kills them on contact!
  • Use a spray bottle with a mixture of water and dish soap. It suffocates them when they come into contact with it.
  • Spray ant spray containing boric acid or diatomaceous earth on their trails to make sure none escape from their nest (the ant’s nest)

How Do I Keep Ants Out Of My Yard Permanently?

Although it is possible to keep ants out of your yard permanently, this task can be difficult. Ants thrive in warm, humid weather and are attracted to sweet liquids such as soda pop or juice. To prevent them from being drawn into your house or yard, it’s important to keep these things away from where ants live by:

  • Keeping grass mowed short and keeping the ground clear of debris
  • Keeping garbage in containers with tightly fitted lids
  • Keeping pet food in containers with tightly fitted lids (or not feeding pets outside at all)
  • Cleaning up crumbs around the house immediately after eating meals inside

How Do I Avoid Having Ants In My Home?

Keep your house clean. Ants are attracted to filth and clutter, so keeping a tidy home can help keep ants out of it.

Keep your kitchen clean. Other than being an attractive place for food crumbs, kitchens are also one of the most common areas for ants because they contain many different types of food (not just sugar!) as well as other substances like grease or oil that ants love to feed on. 

It’s important to keep these things clean and tightly sealed away from ant access!

Don’t leave pet food outside overnight; make sure there isn’t any lying around on the ground–and don’t let your pets eat any either! 

Pet food contains protein which is very attractive to ants; if you’re feeding them inside then this isn’t really much of an issue but if they’re eating outdoors then they’ll quickly become riddled with pests until someone steps in with some bug spray 🙂

A garden fork can be a useful tool for aerating your lawn, as we explain in our landscape advice on aerating lawn with a garden fork. This low-cost option can provide a great workout and improve the overall health of your lawn.

Are There Any Natural Ways To Get Rid Of Ants Without Using Chemicals?

The best way to get rid of ants without using any chemicals is to use a mixture of water and vinegar. If you see an ant in your home or on your property, pour a small amount of white vinegar over it. The insect will die within seconds because the acidity of the vinegar will cause its exoskeleton to dissolve.

Baking soda can also be effective against ants if you find yourself with an infestation. Mix baking soda with water until the consistency is thick enough to stay in place when dropped from several inches above the ground surface. 

Once this mixture has dried, any ant that comes into contact with it will die after being coated by its sticky texture. Use caution when applying this solution outdoors because wind may blow away some of these particles and cause them to fall onto other surfaces where they could be harmful if ingested by pets or children (or even adults).

To deal with small groups of ants who have made their way indoors but do not seem interested in leaving yet, try spraying them directly with lemon juice diluted with water (one part lemon juice per three parts distilled water). 

Borax powder sprinkled across all trails leading out from where they entered will also work well at killing these pests quickly since their bodies are so sensitive


In conclusion, ants can be a nuisance and cause damage to your lawn. It is important to know what type of ant you are dealing with before deciding on how best to get rid of them. 

You should also consider the health benefits of natural remedies like vinegar or baking soda as well as insecticides that contain toxic chemicals like boric acid or pyrethrum powder.
