Big Headed Ant

Appearance:  Big headed ants are interesting because there are actually two different sizes of them.  They are categorized as major workers or minor workers.  They are usually about 1/8” to 1/4” in length, and the major workers are noticeable by their unusually large heads.  Their coloring is a mix of red, brown, and pale yellow.

Location & Behavior Patterns:  Big headed ants typically make their nests outdoors, and in the soil.  Occasionally, they will make their way indoors, usually through cracks in a slab foundation or in the soil of potted plants.  They are often spotted in long lines along the edge of a building’s foundation or on sidewalks.  They have also been known to create mud tubes, similar to a termite mud tube, and their tubes are sometimes significant in size.  They are a very popular pest throughout Florida.

 Treatment:  Big headed ants are considered a nuisance pest, and are not harmful to people or property.  Because most of their colonies are relatively small in size, they are easily treatable.  There are also things that you can do, in order to limit the amount of big headed ant nests on your property, such as; rid your property of piles of wood, brick, and other building materials, keep mulch at least a foot away from the foundation of your home, and keep cracks sealed around your structure, thus preventing entry from this, and other, pests.
