What Types Of Ants Are Common In Texas?

Ants appearing in your home or on your property can leave you wondering about the severity of the problem and how to make it go away. If they're crawling around in your kitchen by the hundreds, you may be scratching your head, speculating about what lured them inside. When you see them creating mounds near your walls, it can have you worrying about the species - is it a carpenter ant damaging your home from the inside out, or is it a fire ant ready to sting you or your children?

Determination of the type of ant, behavior of species, and severity of the problem will help you work with a licensed exterminator to make a plan for ant control. Furthermore, different species will affect your health and property in different ways.

Fire Ants

The red imported fire ant is not an ant species native to Texas. Rather, it was originally introduced to the United States from South America. These ants are dark rust-red in color and can reach up to ⅜ inch in size.  They typically build their mounded ground nests outdoors in areas that get a fair amount of sun.  

Unfortunately, these pests have no known predators, and can thus grow in numbers exponentially once they find a place to build their colony.  If they perceive a threat to their nest, the red imported fire ant will attack and sting people, wildlife, or even machinery. If stung, they will leave behind a red welt that can last for up to a week. 

Rover Ants

The Rover ant is not an ant native to Texas. In fact, it’s a fairly new Texas ant species that found its way to the United States from Argentina and Paraguay. Very small in size, rover ants are pale yellow to blackish-brown in color and have relatively large eyes compared to the size of their heads.  

Though they are not aggressive in nature, rover ants do have a tendency to invade properties in large numbers. They are attracted to moisture, and thus build their colonies around rot or fungal decay.  

This Texas ant species is most active during the spring and summer seasons. Unlike other types of ants in Texas, they are not particularly aggressive in nature. However, they are still capable of becoming quite a nuisance. Rover ants are fast and difficult to control; They will travel great distances and invade properties quickly and in large numbers. 

Tawny Crazy Ants

First discovered around Houston in 2002, tawny crazy ants (also known as Raspberry crazy ants) arrived in Texas from South America.  Among the smaller types of ants in Texas, the Tawny Crazy Ant is only about 1/10 inch in length. These ants are reddish-brown in color and are most recognizable by the way they move.  Rather than traveling in a straight line, these small, uniformly-sized ants follow a zig-zag like pattern.  

Since they became among the many types of ants in Texas, tawny crazy ants spread quickly throughout the southern part of the United States. They often show up on properties in large numbers. Their plentiful population along with their ability to bite (they cannot sting) creates a nuisance for landowners. If they make their way indoors, they will often nest in or near electrical equipment damaging the wiring and functionality of televisions, DVD players, light fixtures, and other electronic devices.  

Carpenter Ants

Carpenter ants are among the ants native to Texas.  These large black ants grow to be ½ inch or more in length.  They prefer moist, humid environments and will infest homes while developing and expanding their colonies.  They are often mistaken for termites (and vice versa). However, unlike termites, they do not eat wood. Rather, carpenter ants tunnel through wood to create galleries, and in the process, they leave behind piles of sawdust or “frass” on the floor. This Texas ant species can cause extensive damage to your home or property if left to its own devices.  

Are Ants Dangerous?

Yes and no - it depends on the species.  Some ants are quite dangerous to humans while others are just a nuisance. Some species of ants in Texas are capable of biting or stinging people, pets and wildlife. These red welts are uncomfortable and, though rare can cause allergic reactions in people.  Other species of ants in Texas damage machinery, equipment, and electrical wiring which can be dangerous and costly to repair.  

Where Do Ants Nest?

Like other pests who make their way onto your property or into your home, ants are in search of food, water, or shelter.  Where an ant builds its ideal nest depends on the species.     

  • Fire ants create mounds in open, sunny yards, fields, and golf courses, and avoid shady wooded areas. 

  • Outside, rover ants typically nest underneath stones, leaf litter, loose bark, or in sandy areas. Inside, rover ants are attracted to areas where moisture is present including potted plants, bathrooms, kitchens, and behind wall voids. 

  • Tawny crazy ants create nests outside under landscape ties, mulch, stones, bricks, and organic debris like leaf litter. Inside, these Texas ants nest behind walls and in potted plants.

  • Carpenter ants look for damp, humid, and wooded areas to make their nests. You will find carpenter ant colonies in areas damaged by water or rot such as stumps, dead trees, wall voids, or crawl spaces.

How Can I Prevent Ant Infestations?

Preventing Texas ant species from infiltrating your home or property starts with making conditions for ants as unappealing as possible. 

Exterior Ant Prevention

  • Reduce areas of moisture around your home by ensuring that gutters are working properly. They should be free of debris and direct water away from your home. 

  • Seal any cracks or gaps on the outside of the structure.

  • Fix any leaky outdoor faucets and fixtures.

  • Remove rot and debris away from your yard including piles of organic debris, fallen trees, and downed tree limbs.

  • Ensure that outdoor trash cans have tight-fitting or locking lids; Store trash cans on platforms above the ground.

  • Trim back trees, bushes, and other landscaping so that they don’t touch the exterior of the house or building.

  • Install a barrier between the lawn and the foundation of structures.

  • Before bringing potted plants inside from the outside, inspect them for signs of ants and other insect activity.

Indoor Ant Prevention

  • Check screens and windows making sure that they are completely intact. Repair any gaps or holes.

  • Fix leaking pipes, fixtures, and appliances.

  • Replace any wood damaged by water.

  • Clean up food crumbs and spills as soon as they occur.
