Interaction riskLow
- Low
- Moderate
- High
- Very high
- Why interaction risk is low
- Hornet stings can trigger severe allergic reactions; avoid nests and seek emergency help for systemic symptoms.
- Why it is dangerous
- Workers can sting repeatedly, and venom may cause anaphylaxis in a sensitized person.
- How to recognize a risky encounter
- Look for a very large reddish-brown and yellow wasp, but never approach a cavity to confirm a nest.
- What to do
- Do not swat, trap, or disturb the colony; call emergency services for breathing difficulty or widespread swelling.
Responsible observation
- Distance: Back away calmly if repeated hornet traffic reveals a nest entrance.
- Prevent: Keep lights, food, and sweet drinks managed when hornets are active.
