Species Profile

Pyramid Ants, scientifically known as Tetramorium caespitum, are small to medium-sized ants belonging to the family Formicidae. They are native to Europe but have spread to various parts of North America, where they are considered invasive pests. These ants are known for their distinctive pyramid-shaped mounds of soil and debris.

How to Identify Pyramid Ants

  1. Appearance: Pyramid Ants typically measure between 2 to 3 millimeters in length and are light to dark brown in color. They have a robust body with a distinct waist (segment between the thorax and abdomen). Their antennae consist of 12 segments, ending with a club of three segments.
  2. Nesting Behavior: Look for their characteristic pyramid-shaped mounds, which can reach heights of several inches. These mounds are constructed using soil, small stones, and plant material.
  3. Trails and Foraging: Pyramid Ants establish well-defined trails between their nests and food sources. You may observe them foraging for sweet substances, protein, and other food items.

Extermination Techniques for Pyramid Ants

These baits contain slow-acting insecticides carried back to the colony, eliminating the entire population. Chemical Sprays: Apply residual insecticides around the perimeter of your property, focusing on areas where Pyramid Ant activity is high. Follow the instructions provided by the product manufacturer and take the necessary precautions.
