If you’ve ever walked through your yard only to notice a dome-shaped mound of dirt or, worse, experienced the painful sting of fire ants during routine lawn care, you’re not alone. Fire ant mounds often appear seemingly overnight, especially following rainfall, and can spread rapidly if not addressed.
With a consistently warm climate and dense, clay-rich soils in Texas, fire ants flourish in residential and commercial landscapes across DFW, Houston, Austin, and San Antonio. While various do-it-yourself treatments exist, widespread or persistent infestations typically require a more strategic and professional approach. If you suspect fire ants are already infesting your lawn, consult with certified contractors today.
In this post, we’ll walk you through how to get rid of fire ant mounds in your yard, including tips for tackling large fire ant mounds and when to call in the pros. Learn expert, family-friendly fire ant control tips to help keep your outdoor spaces safe and thriving.
Why Fire Ant Mounds Are a Serious Problem in Texas
Fire ants are aggressive insects that create underground colonies, often hosting thousands of workers. Their painful stings are no joke, each injecting venom that causes a burning sensation and painful pustules.
Here in Texas, our long, hot summers and frequent rainfall provide perfect breeding conditions for fire ants. They build mounds to escape flooding and regulate the temperature of their colonies. The result? Piles of dirt that ruin curb appeal and pose a danger to kids, pets, and anyone walking barefoot.
A single mound may not seem like much, but each queen can produce thousands of eggs daily, allowing them to spread quickly throughout your property. Fire ants can also damage turfgrass roots and harm your garden’s ecosystem without proper treatment.
How To Identify Fire Ant Mounds in Your Yard
Texas property owners and managers should understand the distinct features of fire ant mounds. Here are some of the characteristics to be aware of next time you walk around your yard:
- Mounds appear dome-shaped and loosely built.
- Mounds can measure up to 18 inches wide and 8 to 12 inches tall.
- Mounds are often located in open, sunny areas like lawns, sidewalks, and gardens.
- Mounds lack a visible opening (fire ants use underground tunnels to exit).
Important Note: If you disturb a mound, even slightly, you’ll notice a quick swarm of reddish-brown ants, often with a stinger in tow. This is a telltale sign you’re dealing with fire ants.
Small mounds may look like scattered dirt initially, while large fire ant mounds are more pronounced and can be home to multiple queens. These large colonies are especially tough to manage without expert help.
DIY Methods for Getting Rid of Fire Ant Mounds
Several do-it-yourself methods can help manage or eliminate a limited number of fire ant colonies in your yard, offering an alternative to professional pest control. However, these approaches are generally only effective for smaller infestations:
1. Mound Drench Treatments
Liquid insecticides mixed with water are poured directly on the mound. This can kill the queen if it reaches deep enough, but it's not always reliable, especially for large mounds.
2. Baits and Granules
Slow-acting poisons are spread around the mound and carried back to the colony, which can kill the queen over time. Their effectiveness, however, is often limited by competing food sources, weather, and the deep or multi-queen structure of large Texas fire ant colonies.
3. Boiling Water
Pouring boiling water over a mound can kill surface ants and collapse the structure. However, it rarely penetrates deep enough to eliminate the entire colony and can damage grass or plants.
Reminder: The success of DIY treatments depends on factors like colony size and maturity, the product used, and application consistency. For larger or persistent problems, working with a pest control professional may be the most efficient solution.
How To Get Rid of Large Fire Ant Mounds
Due to their advanced development, established and large fire ant mounds require more thorough treatment strategies beyond simple bait application or the pouring of boiling water. Here’s why:
- Colonies Often Run Deep Underground: The queen and brood can be several feet below the surface.
- Multiple Queens: Some large mounds contain several egg-laying queens.
- Limited Reach: Store-bought solutions may not penetrate deep enough or apply evenly.
