Natural Ant Killer:

We have had ant problems around the house and lawn, off and on for quite a few years. I always notice some years are worse than others.

While having the insect exterminators spray for ants is the ultimate fix, we have a few reasons for trying to avoid calling them if possible. For one, we are always concerned about our organic garden getting over sprayed by insecticides.

We also have a few pets around the house that will sometimes naughtily get into plants or vegetables. The last thing I want is to worry about pesticides all over the place.

Of course, ants are everywhere outside, and we don’t necessarily want to rid ourselves of all of them since they do eat other more destructive insects, and often keep to themselves. It’s only when they are taking over we have to do something about it!

So, we researched a few natural methods of getting rid of ants, and keeping them gone! Check out these Natural Ant Killers or Deterrents here!

Cinnamon for natural ant killer

CINNAMON:

Ants do not like the strong smell and taste of cinnamon. The good thing is that it won’t harm your plants! Just sprinkle cinnamon around the base of your plants where the ants are forming their usual trails.

For this purpose, I would use the cinnamon that you can find in bulk, either at the bulk shopping grocery store like Winco, Costco, and Sam’s. Or find it here on Amazon.

There is no difference in quality of cinnamon here, so use what you can find at the lowest cost.

Peppermint plant

PEPPERMINT:

If you have the opportunity to plant Peppermint, give it a try! This companion plant smells great and naturally deters insects.

If you don’t have room or just don’t feel the need to invest in peppermint plants, you can try crushing small amounts of peppermints around the garden. Use caution around pets and don’t use any sugar free varieties since they can be toxic to dogs.

DIATOMACEOUS EARTH

DIATOMACEOUS EARTH:

This natural, powdered sedimentary rock is a very fine form of fossilized diatoms. Since it’s so coarse and absorbent it works well as a natural pesticide.

Diatomaceous Earth absorbs lipids from the exoskeleton of the ants and makes them susceptible to dehydration. Since it’s naturally found in the environment, you don’t have to worry about adding harsh chemicals to your lawn and garden.

Find Diatomaceous Earth on Amazon, and in natural food and health supply stores.

lemons and oranges

LEMONS & ORANGES:

Most of us don’t have a lemon or organe tree on the property, but if you buy fresh fruits often, be sure to save those peels!

You can run them through the food processor to rough chop them, then scatter around plants as a Natural Ant Killer. Use pieces about the size of a quarter in the garden. Citrus oil is toxic to certain kinds of ants!

white vinegar

VINEGAR:

I buy my vinegar in bulk since I use it all over the house for natural cleaners and more.

For repelling ants you can use a 1:1 mixture of vinegar and water.

Use a spray bottle and label properly so you’re not guessing at which spray to use.  🙂 This vinegar and water mix can be sprayed directly onto ants to kill them.

It’s also great for those ant trails you see inside the house…the last thing I want to use in my kitchen and around food is a bug spray! This one works just fine and you can wipe it up with a towel. So easy. Pets do not like the scent of vinegar but it shouldn’t be harmful. Be sure to wipe up immediately.

Do not use as a preventative since vinegar is harsh on most surfaces.

cayenne pepper for Natural Ant Killer

CAYENNE PEPPER OR BLACK PEPPER

I had good results with cayenne pepper around the base of my plants. You do have to keep on top of it. Don’t forget to add more as needed.

Cayenne works as a barrier, so for best results sprinkle in a line to block the ants where they usually form a line. You can make a circle around the base of the plant.

CHALK:

Chalk isn’t the first thing we think of when trying to get rid of ants, but if you want to recyle your old sidewalk chalk, this is a way to repurpose it!

Draw a thick line on the concrete where ants usually travel. Although it’s unknown why or how chalk can interrupt ant lines–possibly the scent– they typically will stop and reroute their line.

epson salt- Natural Ant Killer

SALT:

We always have a large side cannister of salt. Be very careful with sprinkling salt on any grass, vegetation, or even the ground, since it can alter the sodium content of your soil. It can kill grass and plants so use carefully.

However, salt water spray and putting down salt granules can deter ants from traveling across concrete and possibly into the house. It’s a good natural ant repellent– think barrier– if you have a lot of it on hand.

Creative Uses for Cornstarch

CORN STARCH

While most of us think of cornstarch for cooking, it can be used as a Natural Ant Killer. This idea works better for large amount of ants in a specific location.

Cover the ants in cornstarch and soak with water, OR cover with corn starch and then vacuum up immediately. If vacuuming, dispose of the vacuum contents outdoors, so you will avoid any stray ants within your home. (Healthline)

It’s important to note cornstarch won’t kill ants on contact so you have to be prepared to remove them.

coffee grounds

COFFEE GROUNDS

Coffee grounds can be good for the garden for several reasons. For one, it supplies soil with acids and extra nitrogen which certain plants love. It can also help keep those pests at bay!

Ants do not like the scent (possibly) of coffee grounds, and it’s a common garden remedy to cover an ant hill with coffee grounds. How well it works might be debatable, however. Since coffee grounds are good for the soil and it’s a great way to re-use and recycle something you probably use anyway, we say give it a try!


I hope some of these tips are useful to you, and will help prevent any unnecessary calls to treat ants. Happy gardening!
