Big-Headed Ants Identification

What are big-headed ants? 

Big-headed ants vary in color from red to brown to light yellow. These ants are unique because the workers come in two different sizes — major and minor. The minor worker's body and head are proportionate in size. The major worker's heart-shaped head is noticeably larger than the rest of the body.

Are big-headed ants dangerous?

Big-headed ants construct mud tubs, which often cause them to be confused with wood-eating termites. However, unlike termites, these ants don't feed on wood and aren't responsible for causing structural damage. 

Big-headed ants build supercolonies, a series of connected smaller colonies, which allow them to gather food and distribute it to all their colony members. This behavior and multiple nesting sites can make them difficult to control and eliminate.

Like most other ants, big-headed ants are also annoying to deal with on our properties. They forage for food and moisture and create nesting sites, leaving behind piles of debris and dirt. When in our homes, they will contaminate food and surfaces with bacteria and other pathogens they came into contact with outside.

Why do I have a big-headed ant problem?

Big-headed ants are omnivores and will feed on other insects, honeydew, proteins, grease, and sweets. They will forage for food in our Florida yards in the following places:

  • Gardens that offer a lot of insect activity.

  • Trash cans and recycling bins.

  • Pet food.

  • Outdoor eating areas.

Food odors and moisture will also attract these ants to the outside walls of buildings. As they travel over them, they move inside through cracks in the foundation and spaces around windows and doors. 

Where will I find big-headed ants?

Outside, these ants build nests in open, well-shaded areas, including next to the foundations of homes and other structures. The soil next to trees, patios, sidewalks, driveways, and pavers are examples of other areas these ants like to nest. As ants create their nesting galleries, they move the soil they excavate up to the surface of the ground and through cracks in pavement, cement, walls, floors, and baseboards. 

Big-headed ants also move into our homes while seeking moisture and food. Once inside, it is common for them to stay and build a satellite nest to expand the colony. They prefer to nest behind walls in areas where moisture is present (pipes, fixtures, tubs, sinks, air conditioners). 

Wall void in basements, kitchens, and bathrooms are common areas in a home to find these ants nesting. Spaces behind windows and doors are other favorite nesting sites.
