Types of Ants in Texas
Ants are among the most persistent and adaptable pests in the Texas ecosystem. Whether it's your home, lawn, or commercial property, chances are you've had a run-in with these six-legged intruders. What makes ants challenging is their ability to build large colonies quickly, adapt to changing environments, and enter through even the smallest cracks in search of food and shelter.
Across the Lone Star State, ants are not just a nuisance. They can cause painful stings, structural damage, and even short circuit your electronics. In suburban areas, ants can move between homes via fence lines or underground tunnels. In more rural settings, large colonies can stretch across multiple acres and displace native ant populations. This comprehensive guide helps Texas homeowners and property managers understand the different types of ants in Texas, how to spot them, what attracts them, and most importantly, how to keep them out.
Common Ant Species in Texas
Texas is home to more than 250 known species of ants, but only a handful are commonly encountered in residential and commercial settings. Each species behaves differently, requiring a unique approach to identification and control. Here's a breakdown of the most common ants in Texas:
Red Imported Fire Ants
Perhaps the most notorious ant species in Texas, red imported fire ants are aggressive and capable of delivering painful, venomous stings. They build large, dome-shaped mounds, often in sunny areas like lawns, sidewalks, and playgrounds. These ants are known to attack anything that disturbs their nests, including humans and pets.
Fire ants pose a serious risk to people with allergies and can damage young plants and electrical wiring. Colonies can grow rapidly and spread by both budding (splitting into new colonies) and through queen flights. Learn more about them from the Texas A&M Agrilife Extension.
Carpenter Ants
Unlike termites, carpenter ants do not eat wood, but they excavate it to build their nests, which can weaken structural beams and support. These large black ants are often found in moist, decaying wood in attics, decks, and wall voids. Their presence can be subtle until the damage becomes extensive, making early detection vital.
Carpenter ants often become active at night and are drawn to sugary substances and pet food. Seeing large black ants during nighttime hours is a strong indicator of an active nest nearby.
Odorous House Ants
Named for the rotten coconut-like smell they emit when crushed, odorous house ants are tiny but persistent. They nest in walls, under flooring, and near moisture sources like sinks or leaky pipes. These ants are drawn to sweet substances and can contaminate food if left unchecked.
They are known to form multiple interconnected colonies, which makes elimination difficult. Using sweet-based baits is often effective, but professional-grade solutions yield better long-term results.
Crazy Ants
Recognizable by their erratic, jerky movements, crazy ants are a relatively new nuisance in Texas. They do not form centralized mounds but instead scatter into multiple subcolonies, making them extremely difficult to eliminate. They love warm, moist areas and often infest electronics and HVAC systems, sometimes causing short circuits.
Originally from South America, crazy ants are displacing fire ants in some areas of the Gulf Coast due to their sheer numbers and reproductive rate. They are highly adaptive and can survive indoor and outdoor conditions year-round.
Acrobat Ants
These ants get their name from the way they raise their abdomen above their head when disturbed. Acrobat ants prefer decayed wood, foam insulation, and are often found trailing along electrical wires or plumbing. Their bite is mild, but their presence indicates moisture issues or rotting wood in the structure.
Homeowners should inspect soffits, siding, and crawlspaces for signs of moisture damage when acrobat ants are found indoors.
How to Identify an Ant Infestation
Early detection of an ant infestation can prevent major issues down the road. Be on the lookout for these telltale signs:
- Long trails of ants traveling to and from food sources
- Small piles of sawdust near wooden structures (carpenter ants)
- Ant mounds with no visible hole on top (fire ants)
- Unusual ant activity near electrical outlets or wiring (crazy ants)
- Swarmers or winged ants emerging indoors
Other clues include rustling or faint clicking sounds in walls, pets reacting to insects near feeding areas, or large clusters of ants appearing after rainfall. Keeping a pest journal can help track frequency and severity.
What Attracts Ants to Your Property?
Understanding what brings ants to your property is key to prevention. Some of the most common attractants include:
- Food crumbs, spills, and unsealed pantry items
- Pet food left out in bowls or storage bins
- Leaky faucets, drains, or areas of standing water
- Moist, shaded landscaping or mulch beds
- Gaps in windows, doors, and foundation lines
In addition to food and water, ants are drawn to heat. Electronics and appliances can emit warmth that attracts certain species, especially crazy ants. Seasonal changes and droughts may also drive outdoor ants indoors in search of better conditions.
Preventing and Controlling Ants
Prevention Tips
- Seal all entry points, including cracks, windows, and doors
- Clean floors and countertops regularly to remove food debris
- Store food in airtight containers
- Empty trash bins frequently and use sealed lids
- Maintain your yard by trimming vegetation and clearing debris
- Fix water leaks and improve indoor ventilation
- Avoid overwatering lawns and gardens
These steps create a hostile environment for ants and reduce the chances of a scout ant marking a food trail back to its colony.
Avoid DIY Mistakes
Over-the-counter sprays and traps might kill a few ants, but they rarely eliminate the colony. In fact, some DIY treatments cause ants to scatter and form new colonies, making the problem worse.
Misidentifying the ant species can also result in selecting the wrong bait type, rendering the treatment ineffective. Always match the bait (protein, sweet, greasy) to the ant’s foraging behavior.

- You find large ant trails inside or outside your home
- Ants return even after cleaning or using store-bought traps
- You notice structural damage or hollow-sounding wood
- Children, elderly, or pets are at risk from stings
