If you live in an area infested with fire ants, you know how frustrating it can be to deal with them in your vegetable garden.
So today, we’ll discuss different methods that people commonly use to get rid of fire ants and why they may not be effective, then I’ll share what I’ve discovered that has shown VERY promising results.
The Challenge of Fire Ants in the Vegetable Garden
Living in fire ant country in the south, I have struggled with these pests in my own garden.
Despite knowing that fire ants are attracted to organic matter and covered areas, I have chosen to use wood chips and weed fabric in my gardening methods.
While these choices have their benefits (which I believe outweigh the cons), they also create an ideal environment for fire ants to build their nests.
And so my search to find a safe, natural way to get rid of fire ants began….

Ineffective Ant-Killer Methods I’ve Tried
Traditional insecticides are not an option for me as I want to avoid toxins on vegetables that my family will eat. As such, I’ve stuck to natural remedies.
I have tried several popular methods found on social media:
- Pouring grits on the ant mound
- Using boiling water
- Lighting them on fire
- A Dawn dish detergent solution
- Scooping one ant hill into another
They have all failed to eliminate the fire ants from my garden.
The Importance of Killing the Queen Ant
One of the main reasons why these methods fail is that they only kill ants on the surface and do not reach the queen.
To effectively eliminate a fire ant colony, it is crucial to kill the queen.
Without eliminating the queen, the mound will either bounce back right where it was or move just a few feet away.

After extensive research and consulting with local experts, I have discovered a potential solution to the fire ant problem—a spinosad drench.

Spinosad is a natural bacteria found in soil that is toxic to certain insects, including fire ants. It acts as a nerve agent, paralyzing the insects over time.
While it may take a couple of weeks to see results, this method has shown promise in killing the entire colony, including the queen.
How to Apply a Spinosad Drench
To apply the spinosad drench, you will need two ounces of spinosad insecticide mixed into a gallon of water—and you’ll need two gallons total.
Create a barrier around the ant mound using half of the solution in one jug, then drench the entire mound with the remaining solution and second jug of solution.
It is important to thoroughly saturate the mound and any areas where ants are surfacing.
Unlike other methods that claim instant results, spinosad takes time to work. It may take up to two weeks for the solution to fully eliminate the fire ant colony.
During this time, it is important to resist the urge to disturb the mound or take any further action.
The Results Speak for Themselves
After two weeks, it’s time to check if the spinosad drench was successful.
Check out the video above to see the proof!
Carefully observe the ant mound and surrounding area for any signs of activity. If there are no visible ants and the mound appears lifeless, disturb the mound with a preferably long stick (and from a safe distance).
Congratulations—you have successfully eliminated the fire ant colony from your vegetable garden!
If, by chance, the mound is still active after 2 weeks, repeat the process.
(That said, I haven’t had to repeat the drench more than once per mound.)
Dealing with fire ants in your vegetable garden can be a frustrating experience, but with the right approach, it is possible to eliminate them without resorting to harmful pesticides.
The spinosad drench method offers a natural and effective solution that targets the entire colony, including the queen.
By following the steps outlined in this article and being patient, you can enjoy a fire ant-free garden and protect your fresh veggies!
