Beneficial Ants

Believe it or not, there is a beneficial ant that is found in many landscapes. If you see an interesting mound shaped like a small volcano, you likely have the pyramid ants. These ants form small nests in sandy soils and the mound will have a small opening in the very center.

Pyramid ants are not aggressive and do not sting. They are fast moving over the ground building the mound and searching for food. Ants will collect honeydew from other insects and the beneficial part is that ants hunt live insects including winged fire ants. By allowing the pyramid ants to remain in parts of your landscape, you may reduce the numbers of fire ants that can establish in that area.

When you see the distinctive pyramid ant mounds, remember the beneficial role they play in keeping pest species in check. Keep any baits away from these areas to protect the pyramid ants.

  1. Thank you very much for this information. Ants can be such a positive force in the landscape, but we’re tempted to tar all ants with the reputation of fire ants.

  2. Thanks for the good information. I really enjoy learning about ant species.

  3. Thank you for this, Mary and Beth.
    Had no idea; now to teach the husband and his ant killer mania.
