Leafcutter Ants: Identification, Habitat, Behavior, and Control

A symphony of nature right in your backyard, leafcutter ants are fascinating creatures. Their coordinated effort to cut leaves, form lines, and transport these fragments back to their nests is truly an incredible sight. However, the very behavior that makes them fascinating can also make them a nuisance, especially when they set their sights on your lush garden or valuable crops. If you’ve noticed telltale signs of leafcutter ant activity around your property, it’s time to consider professional pest services.

Leafcutter Ants


Leafcutter ants are a group of species that are particularly recognizable for their behavior of cutting leaves and other vegetation, which they transport uniquely and distinctively back to their colonies. They belong to two genera – Atta and Acromyrmex. They are primarily found in South and Central America, with some species in parts of the United States.

Here are some features to identify Leafcutter ants:

  1. Size: They range from 0.7 mm wide (head size) to  5 mm wide, depending on their caste.
  2. Color: Leafcutter ants are generally dark red.
  3. Behavior: They are known for cutting out leaf fragments and carrying them over their heads in a line back to their nest.
  4. Nests: Their nests are large, complex underground systems extending up to 23 feet deep. Large mounds of excavated soil often mark the surface of the nest.
  5. Caste system: Like many ant species, leafcutters have a caste system with distinct roles, including workers, soldiers, and the queen.

Latin Names

The Latin names for leafcutter ants fall under two genera:

  1. Genus Atta: This includes Atta cephalotes, Atta texana, and several others. These ants are often larger, and their colonies contain millions of individuals.
  2. Genus Acromyrmex: This includes Acromyrmex octospinosus, Acromyrmex echinatior, and others. These are often smaller ants, and their colonies are typically smaller than those of the Atta.


Extermination Techniques

Leafcutter ants can be a nuisance due to their leaf-cutting behavior, which can harm crops and ornamental plants. If you have a problem with leafcutter ants, here are some common extermination techniques:

  1. Insecticide baits: Specific baits developed for leafcutter ants are effective. The ants carry the bait back to their colony, where it is distributed among the population, leading to the extermination of the entire colony.
  2. Chemical insecticides: Applying insecticides directly to ant trails and around nest openings can also be effective. However, this method usually only kills the ants you see and may not reach the whole colony.
  3. Biological control: Certain fungi and insects are natural predators of leafcutter ants and can be used as a biological control method. This technique, however, requires a good understanding of the local ecosystem and may not be practical for everyone.

Please note: Any extermination technique should be carried out responsibly.
