What Are Ant Mounds?

Acting as entrances to ants’ subterranean nests, ant mounds are comprised of soil and can reach as high as three feet in some species such as the Allegheny mound ants or fire ants.

Characteristics of Ant Mounds
They typically have holes in their center but may vary in shape depending on the species. Some are shapeless while others look like ancient burial mounds with radii of up to four feet.

Certain species of ants put pebbles around the entrance, while others create cone-shaped hills of sand.

Common Locations

Anthills commonly appear in:

  • Golf courses
  • Flower beds
  • Throughout lawns

Specialized species of ants build nests in or under:

  • Cracks in pavement
  • Under rocks
  • In fallen trees

They flourish in urban, suburban, and rural environments and on varying landscapes, from swamps, forests, and grasslands to deserts and mountains.

Problems Caused by Ant Mounds

Landscaping Obstacles
Homeowners experience problems when ant mounds are constructed in lawns and flower beds, as some anthills are large and look unattractive on private properties.

They also inhibit the growth of grass and some plants. Individuals may have trouble mowing lawns where ant mounds are present.

Finally, having a colony of ants so close to homes often leads to indoor infestations.


Eliminating ant mounds can take more effort than individuals expect.

Call on the Pros
As such, it’s essential to contact pest control experts, who successfully eradicate ant populations by killing queens. Queen ants reside two to three feet underground and can be difficult to eliminate without the proper training.

Professionals have the appropriate equipment and experience to reduce and eliminate ant pressures in and around your home.
