Here’s How You Can Get Rid of Fire Ants

Fire ants are a species of ants that are known for their painful sting and aggressive behavior. They are typically found in warm, humid environments, and build large colonies in soil, often in lawns and gardens. Fire ants can cause damage to crops and other plants, and their stings can be dangerous for humans and pets.

These ants are a common pest in many parts of the world and can be a nuisance to homeowners and gardeners. In this guide, we will discuss different methods of fire ant control, including non-chemical and chemical treatments, as well as preventive measures to prevent re-infestation.

Identifying Fire Ants

Before implementing any fire ant control methods, it is important to properly identify fire ants. Some of the physical features and behaviors of fire ants include:

Physical Features

  • Reddish-brown coloration
  • Ranges in size from 1/8 inch to 1/4 inch
  • Elongated, segmented body with three sections (head, thorax, and abdomen)
  • Antennae and mandibles


  • Aggressive behavior, with stings that are painful and can cause anaphylactic shock
  • Build large colonies in soil, often in lawns and gardens
  • Nests are often visible as mounds or dirt in the ground

Non-Chemical Methods

There are several non-chemical methods for fire ant control, including:

Boiling Water

  • Pouring boiling water into fire ant mounds can kill the ants and destroy the colony.
  • This method is most effective for small colonies, and multiple applications may be necessary for larger colonies.

Diatomaceous Earth

  • Diatomaceous earth is a natural powder made from fossilized algae that can be sprinkled on fire ant mounds.
  • The powder will stick to the ants and dry them out, ultimately killing them.

Natural Predators

  • Several species of birds, such as woodpeckers and quail, are known to prey on fire ants.
  • Some parasitic flies and wasps can also be effective in controlling fire ant populations.

Baking Soda Method

One popular non-chemical method for fire ant control is the use of baking soda. Baking soda is a natural and non-toxic substance that can effectively kill fire ants.


Baking soda works by disrupting the pH balance in the ant’s body, causing it to die. The effectiveness of baking soda as a fire ant control method has been supported by several studies.

Step-by-Step Guide

Here are the steps to follow for using baking soda to control fire ants:

  1. Locate the fire ant mound and clear any debris or obstructions from the area.
  2. Sprinkle baking soda over the mound, using enough to cover the entire area.
  3. Wait several hours, or overnight, for the baking soda to take effect.
  4. Rinse the area with water to remove any excess baking soda.


While baking soda is a safe and natural substance, it is important to take some precautions when using it for fire ant control:

  • Wear gloves to avoid contact with the ants and baking soda.
  • Keep baking soda away from pets and children, as it can be harmful if ingested in large amounts.

Chemical Treatments

Chemical treatments are another option for fire ant control, and can be effective in reducing populations quickly. There are two main types of chemical treatments for fire ants:


  • Baits are a type of chemical treatment that use a slow-acting poison to kill fire ants.
  • The bait is typically placed near the ant colony, and the ants will carry it back to the nest, killing the entire colony over time.


  • Insecticides are a more direct method of fire ant control, and can kill ants on contact.
  • Insecticides can be applied as a spray, granules, or dust, depending on the product.

Safety Concerns

When using chemical treatments for fire ant control, it is important to follow all safety instructions on the product label, including:

  • Wearing protective clothing, such as gloves and a mask
  • Keeping children and pets away from the treated area
  • Using the product in a well-ventilated area

Preventing Re-infestation

Preventing re-infestation is an important part of fire ant control, and can be achieved through proper yard maintenance and sealing entry points.

Yard Maintenance

  • Regular mowing and trimming of grass and vegetation can help reduce fire ant populations.
  • Removing debris and clutter from the yard can also make it less hospitable to fire ants.

Seal Entry Points

  • Sealing entry points, such as cracks in foundations and doors, can help prevent fire ants from entering the home.
  • Installing weatherstripping and screens on windows and doors can also be effective in keeping fire ants out.


  • Regularly monitoring the yard for signs of fire ants can help prevent re-infestation.
  • Early detection and treatment of fire ant colonies can help prevent them from spreading and becoming more difficult to control.


Fire ants can be a nuisance and a danger to humans and pets, but there are several methods for controlling their populations. Non-chemical methods, such as boiling water and baking soda, can be effective and safe options, while chemical treatments should be used with caution and according to label instructions. Preventing re-infestation through proper yard maintenance and sealing entry points is an important part of fire ant control. By implementing these methods, homeowners can effectively control fire ants and protect their property and loved ones from their harmful stings.
