Interaction riskLow
- Low
- Moderate
- High
- Very high
- Why interaction risk is low
- Large workers can cut skin with powerful jaws when a trail or nest is disturbed.
- Why it is dangerous
- Major workers have strong cutting mandibles and may bite repeatedly when their trail or colony is threatened.
- How to recognize a risky encounter
- Look for organized columns of differently sized rust-brown ants carrying freshly cut vegetation toward a large nest.
- What to do
- Do not touch workers, trails, or mounds; step around columns and keep children clear of nest entrances.
Responsible observation
- Distance: Stand beside active trails rather than across them.
- Watch: Follow workers carrying cut pieces without touching the column.
- Protect: Never dig into mounds or block nest entrances.
