Lawn Ant Control - How to Keep Ants From Destroying Your Yard

Lawn ant control begins with a healthy and well maintained lawn. Lawn ants will most frequently attack your lawn if it is unhealthy and stressed. They tend to be most troublesome during the hot, dry weather.

Walk down any block in your neighborhood. At least 3 - 5 houses will have lawn ant hills in their front yard. They are one of the most common lawn pests.

The lawn ants themselves are not usually harmful to your lawn. They may actually help your lawn by feeding on aphids and lawn grub larvae.

They are a nuisance to you and your pets though.

The threat they bring to your lawn is in the ant hills they build.....

  • The grass roots may become exposed. This can kill the individual grass plants in your lawn.
  • Cause uneven areas in your lawn. If this happens it can be more difficult for you to cut the grass.
  • Smothers the grass around them.
  • Grass plant doesn't get the proper sunlight.

You should tackle lawn ant control when the number of ant hills exceeds your tolerence level.

Quick Lawn Ant Diagnosis

One hot dry August day, a long time lawn customer was upset. In some areas her grass began to look like hay. She thought one of my lawn mowers had a gas leak and this was the cause of her lawn problem. I quickly reassured her that I would never use a lawn mower with a gas leak on her lawn.

After further examination, I noticed her neighbors on both sides had the same problem. I explained that it appeared to be the early stages of lawn ants. She relied on my expertise and allowed me to apply an insecticide to the problem areas.

As I was cutting her lawn the following week, I noticed that both of her neighbors had ant hills all over their yards. My customer came out to greet me and thank me. If I didn't make a quick diagnosis the previous week, her lawn may have looked just like her neighbor's lawns.

Lawn Ant Control - Getting Rid of Ants in Your Lawn

Ants in lawn........There are four approaches you can choose from to get rid of them.

  • Mow high and don't worry about them. What you don't see, won't stress you out.
  • Practice good lawn maintenance.
  • Apply a synthetic pesticide.
  • Apply a natural ant control.

Mow high and don't worry about them.

The first option is self-explanatory.

Practice good lawn maintenance.

Your best defense is to keep your lawn healthy and stress free. Follow your lawn care schedule. Cut the grass the right height. Feed your lawn and soil the nutrients it needs. Water your lawn as necessary.

Apply a synthetic pesticide.

Another option you can consider is using a synthetic pesticide to spot treat the ant hills. Your local lawn and garden center sells a variety of products (i.e. Bayer Advanced Triple Action Ant Killer Granules, Ortho "Ant B Gon" Dust, Ortho "Ant B Gon" Bait or a general insect control for lawn and landscape). From my own personal experience, granular products work the best. If you have a large scale problem use a chemical with Bifenthrin. Always read the label carefully when using chemicals.

Bayer now manufactures products that you can use around your own home. Their products are easy to use and very effective in solving your lawn problem.

Apply a natural ant control.

Last but not least......You can practice natural ant control. This also can be the least expensive method. There are many organic ant control options. Here are a few ideas.

  • Take 3 quarts if boiling water and pour it over the ant hill. Once the area dries, in a blender mix equal parts of orange rinds and water. Apply the homemade concoction to the ant hills.
  • Mix sugar and borax in a jar lid. Place the lid near the ant hill. The worker ants will be attracted to the sugar. They will bring it back to the ant hill. The borax on the sugar will kill the lawn ants. If this is the method you choose be extremely careful not to pour the borax directly on your lawn. If you do, it will kill your grass as well as the lawn ants.

Once you finish getting rid of ants in the lawn, you can begin planting grass seed. First, level out the ant hill with a rake. Next, add a little nutrient rich top soil to the area. Finally, plant grass seed on the affected area. Be sure the area receives the appropriate amount of water.

Once the lawn ants are gone, practice proper lawn maintenance to keep your lawn healthy and stress free.
