Big-headed ants are so named because of the appearance of their main colony workers. They are easy to distinguish because they have notably large heads in relation to the rest of their bodies. Conroe homeowners often find these ants underneath the slabs of their homes, or near to the foundation. Sometimes these ants find their way inside through foundational cracks or through other entryways indoors around doors and windows. Most species of ants can be difficult to get rid of once they’re indoors, so it’s a good idea to know what type of ants you’re dealing with to help you manage them.
Big-headed Ants (Pheidole)
Big-headed ants don’t often nest indoors, though they may come inside looking for food and possibly moisture. They are considered one of the most aggressive and invasive ant species anywhere, at least to other ant species. There are several species of them in the United States, including in Texas.
Big-headed ants, in addition to nesting underneath slabs/foundations, can also nest under patios, in yard debris, and in soil that has been broken up. Their major workers (the soldiers with the big heads) are about 1/8″ in length and reddish orange to brown in color. They are not as numerous as the minor workers, and their main job is to defend the nest. Their large jaws can crack seeds and puncture surfaces. Minor workers are about half the size of the major workers (~1/16″) live in the colony and feed the young, as well as build the colony itself.
Some species can transmit tapeworms and bacteria, making them a contamination threat to humans. Big-headed ants have never been known to cause structural damage to homes, and they are not known to sting or bite unless they are provoked. They eat just about anything, including other insects, and are, in fact, attracted to areas where other insects abound. Outdoors, enjoy honeydew produced by aphids, while in your house they will search out grease, sweets, high-protein foods, and seeds. In large enough numbers, Big-headed ants can cause some damage to well-kept lawns, fruits and vegetables, houseplants, and packaged foods. They have been known to destroy and contaminate entire pantries.
