Big Headed Ant

Our remedy for big headed ant control

First, contact us. Because big headed ants are soil nesters, their colonies are often easy to see due to piles of displaced soil formed as they excavate tunnels in the ground. Most colonies are small and relatively easy to treat with professional products, but treating infestations involving multiple colonies requires specialized ant control expertise.

How to Identify a Big Headed Ant


Light brown to dark reddish brown; 1/16″ to 1/8″ long.


Big headed ants enter buildings occasionally, preferring to nest in protected soil such as under stones, leaf litter, mulch, patio blocks, slabs and firewood. These ants are also commonly found inside the soil of potted plants, and many big headed ant control problems may be traced to planters. As the name implies, the major workers’ heads are very large in proportion to their bodies.


This species likes to feed on a wide variety of foods including dead insects, plant materials and garbage. The workers are partial to the sweet honeydew produced by aphids, scales and mealybugs. Inside, they forage for meats, grease, liver, molasses, peanut butter, pet foods and fruit juices.

“We’ve always been pleased with Rose Pest.”

“We’ve always been pleased with Rose Pest. Our technician, Jeff, is one of the nicest and hardest working people we’ve met. A few years back, we had a bug problem that we couldn’t find the source of. Jeff took it upon himself to come back day after day to discover the source and wouldn’t stop until he did. Without asking us, he made sure that the products he used in our house were child-safe because he knew we had a baby. These are just a few reasons why we love working with Rose!”
