How dangerous is it to people?

Danger to people: MildLike a bee sting or less. Basically harmless to people.

๐Ÿš‘ If it bites or stings

  • Scrape out a bee sting and cool the spot.
  • If the person has trouble breathing, swelling of the face or throat, or feels faint, it is an allergic emergency: call your emergency number and use their adrenaline pen if they have one.

Always call your emergency number first (112, 000, 911). This is general first aid guidance, not medical advice. First aid basics

โ›‘๏ธ Stay safe

  • Never touch, catch or tease a wild animal, even a small one, and even if it looks asleep or dead.
  • Give it space. If you meet one, stay calm, step back slowly and let it go its own way.
  • If one bites or stings you: stay calm, keep still, call your emergency number (112, 000, 911) or get to a hospital fast. Remember what it looked like, a photo helps.

It is not out to get you. It uses its venom to catch food or to protect itself, and it would much rather hide. More about staying safe
